  40. Specific fuel consumption standard for thermal energy supplied by heating (industrial heating) boiler houses (the maximum permissible technically justified measure of fuel consumption per unit of thermal energy supplied by the source(s) in heating network) is determined as a whole for the organization - legal entity.

  Thermal energy supplied to the heating network is defined as the thermal energy produced by the boiler units, minus the thermal energy used for the boiler house’s own needs, and transferred to the heating network.

  The standard specific fuel consumption for the supplied thermal energy from the boiler house (group standard) is calculated on the basis of individual standards of boiler units, taking into account their productivity, operating time, the weighted average standard for the production of thermal energy by all boiler units of the boiler house and the amount of thermal energy consumption for the boiler house’s own needs.

  The type of fuel specified in the technical data sheet of the boiler is accepted as the design fuel.

  Standards are determined in kilograms of standard fuel per gigacalorie (kg equivalent fuel/Gcal).

  41. The standard specific fuel consumption (SFC) for an organization is determined based on the results of calculations for boiler houses owned by the organization or in possession on other legal grounds.

  NUR can be determined separately for separate divisions(branches) of the organization.

  42. When calculating the NUR, it is not allowed to take into account fuel and energy costs caused by deviations from the rules technical operation and modes of operation of equipment of thermal energy sources, for construction and major renovation buildings and structures, installation, commissioning and commissioning of new boiler room equipment, conservation of equipment not put into operation or decommissioned, experimental and research work.

  43. NUR calculations are carried out for each month of the billing period and in general for the entire billing period based on the calculation results for each month.

  Operation of individual boilers and boiler houses different types fuel in different periods of the year is taken into account when calculating individual standards for specific fuel consumption in the corresponding months.

  NUR can be installed separately for different types of fuel (gas, fuel oil, coal, etc.) in cases where the organization operates boiler houses (groups of boiler houses) using different types of fuel as the main one.

  In this case, the calculation of the NUR for boiler houses, combined into a group by type of fuel, is carried out as for the organization as a whole.

  44. Approved standards may be revised if reasons arise that significantly affect fuel consumption:

  change in the type, class, brand or quality of fuel burned;

  identification by tests of new characteristics of boiler units;

  installation of new and reconstruction of existing equipment, transfer of steam boilers to hot water mode.

  I. General provisions

  released electrical energy from tires and thermal energy from collectors of thermal power plants running on fossil fuels;

  released thermal energy from boiler house collectors.

  3. In this Instruction, the standard specific fuel consumption (hereinafter referred to as NUR) is understood as the maximum permissible technically justified measure of fuel consumption per unit of electrical energy supplied from the tires, per unit of thermal energy supplied to the heating network. Standards are determined in grams of standard fuel per 1 kilowatt hour (g equivalent fuel/*), kilograms of standard fuel per gigacalorie (kg equivalent fuel/Gcal).

  4. The primary objects of NUR calculations at thermal power plants with steam turbine units are groups and subgroups of equipment. An equipment group is a set of condensing turbine units or turbine units with adjustable steam extraction and back pressure (for power units also with the same power), as well as all boilers (both pulverized coal and gas and oil) that ensure the operation of these turbo units. The subgroup of power units includes a set of only pulverized coal or only gas-oil boilers and condensing or heating turbine units working together with them with the corresponding fresh steam pressure and the same power. A subgroup of cross-coupled equipment is a set of condensing or heating turbine units with the same parameters of fresh steam and boilers that ensure the operation of these turbine units and burn only solid or gas-oil fuel.

  If pulverized coal and gas-oil boilers operate on a common fresh steam collector, then the subgroup of equipment with cross connections is conventionally considered pulverized coal.

  For thermal power plants equipped with combined cycle gas units (hereinafter referred to as CCGTs) or gas turbine units (hereinafter referred to as GTUs), as well as diesel generators (hereinafter referred to as DGs), NUR calculations are performed for each piece of equipment.

  The standard specific fuel consumption for the supplied thermal energy from the heating (industrial heating) boiler house (group standard) is calculated on the basis of individual boiler standards taking into account their productivity, operating time, the weighted average standard for the production of thermal energy by all boilers of the boiler room and the amount of thermal energy consumption for their own boiler room needs. Individual standard specific fuel consumption is the standard consumption of the calculated type of fuel for the boiler to produce 1 Gcal of thermal energy under optimal operating conditions.

  Thermal energy supplied to the heating network is defined as the thermal energy produced by the boiler units minus the thermal energy used for the boiler house’s own needs and transferred to the heating network.

  5. For steam turbine and gas turbine thermal power plants with an installed electrical capacity of 10 MW or more and boiler houses with a heating capacity of 50 Gcal/h and above, NUR calculations are carried out on the basis of the normative and technical documentation (hereinafter - NTD) in force at the time of calculations for fuel use.

  7. If the actual values ​​of the indicators exceed the indicators of the energy characteristics of the equipment (in terms of the efficiency of boiler and turbine units, vacuum, feed water temperature, electricity and heat costs for own needs, etc.) in the year preceding the calculated one, the NUR values ​​calculated based on the normative and technical documentation for fuel use, are adjusted downwards by the amount of fuel savings compared to the energy characteristics obtained in the previous year.

  8. The selection of the composition of operating equipment and the distribution of electrical and thermal loads between individual units of power plants and boiler houses are based on the principles of ensuring reliable energy supply to consumers and minimizing fuel costs for energy supply.

  9. NUR calculations are carried out for each month of the settlement period of regulation and in general for the entire settlement period. NURs as a whole for the billing period are determined based on the results of their calculations for each month.

  III. Methodology for calculating specific fuel consumption standards for thermal power plants and boiler houses

  Calculation of NUR based on regulatory and technical documentation for fuel use

  20. If a thermal power plant or boiler house has a valid normative documentation for fuel use, NUR for the electrical and thermal energy supplied by the power plant, NUR for the thermal energy supplied by the boiler house are calculated in the sequence regulated by the layout for calculating nominal indicators and specific fuel consumption standards.

  Calculations are performed for each turbine unit and each type of boiler units included in the equipment group.

  For the group as a whole, indicators are determined by summing or weighing the results of calculations of the indicators of turbine and boiler units included in its composition. In general, for the power plant (boiler house), indicators are determined based on the results of their calculations for individual groups.

  21. The expected values ​​of indicators for the power plant (boiler house) characterizing the volume of energy production, modes and operating conditions, external factors, reserves of thermal efficiency and the degree of their use are taken as initial data.

  The main of these indicators include (for each month of the forecast period):

  supply of heat to consumers in pairs for technological needs;

  heat release in hot water to the heating network;

  structure of burned fuel and its characteristics;

  outside air temperature;

  condenser cooling water temperature;

  composition of operating equipment.

  In relation to a specific power plant (boiler house), the full composition of the initial data is listed in the layout included in the technical documentation for fuel use.

  Electricity generation by power plants is accepted in accordance with forecast energy balances agreed with the Regional Dispatch Office and the executive authority of the constituent entity of the Russian Federation in the field of state regulation of tariffs.

  22. When calculating the predicted heat loads of production and heating turbine extractions (back pressure) in mandatory the principle of their priority use is observed in comparison with peak water heating boilers (hereinafter - PVK), reduction-cooling units (hereinafter - ROU).

  Total heat supply from production extractions (back pressure) of turbines (*), Gcal, in general view determined by the formula:

  where * is heat supply to external consumers, Gcal;

  *, *, * — heat consumption for own, household needs, peak boilers, Gcal;

  * — heat consumption from ROU connected to a steam source more than high pressure, Gcal.

  Heat consumption for own needs is calculated according to the corresponding dependencies included in the energy characteristics of the equipment.

  Heat supply for economic needs is accepted according to the actual data of the period preceding the calculated one.

  Heat consumption for peak boilers is calculated using heat balance equations.

  Heat release from turbine heating outputs (backpressure) generally includes:

  heat supply to external consumers (*), for own (*) and household needs (*) from heaters connected to these extractions;

  heat consumption for heating an additive that replenishes the non-return of condensate from consumers of steam extractions of higher potential (*).

  The expected value of the total heat supply from turbine heating outputs, Gcal, can be calculated using the formula:

  where * are heat losses associated with its supply to external consumers in hot water;

  * — expected heat supply from PVC, Gcal.

  Heat supply from peak hot water boilers (peak boilers) is calculated based on the forecast of the duration of the outdoor air temperatures (*), at which they need to be turned on to ensure compliance with the temperature schedule of the heating network:

  where * is the flow of network water through peak hot water boilers or peak boilers, t/h;

  *, * — enthalpies of network water in front of PVC (peak boilers) and behind them, kcal/kg.

  When distributing electrical and thermal loads between individual units of a power plant, it is advisable to strive to minimize the heat consumption of the turbine unit for electricity generation.

  For this, special computer programs are used. In the absence of such programs, the following recommendations should be followed.

  In the case of the power plant operating in the calculation period according to the thermal schedule, the turbines with the highest total specific electricity production for the heating cycle compared to other turbines of the subgroup are loaded first.

  When a power plant operates according to an electrical schedule, the distribution of thermal and electrical loads is interconnected.

  If there are several subgroups of equipment at the power plant, it is advisable during the period of maximum electrical load transfer heat loads to a subgroup with lower initial parameters of fresh steam in order to maximally limit its condensing electricity generation. Moreover, a greater effect can be achieved when transferring the heating load.

  When turbines operate with electrical loads close to the nominal ones, in order to achieve maximum cogeneration power generation, the selections of units of the same type are loaded evenly.

  The summer period of operation of units with low loads predetermines the uneven nature of the distribution of thermal load between turbines until it is transferred to one of them.

  When PT and R type turbines operate in parallel, first of all, as calculations show, the outputs of PT type turbines are loaded until highest values total specific cogeneration electricity generation.

  When distributing thermal loads, the following are taken into account:

  restrictions by manufacturers on the minimum load of turbine extractions;

  features of the heating installation scheme in terms of heat supply to external consumers and for internal needs;

  reliability of heat supply to consumers.

  After distributing thermal loads according to mode diagrams and standard characteristics, the minimum electrical power of each turbine and the minimum electricity generation by the power plant (*), thousand * are determined:

  where *, * is the power developed by turbines of type P (or turbines of type PT, T when working with deteriorated vacuum) and the minimum power of turbines of type PT and T at given extraction loads (backpressure), thousand kW.

  The value * includes the heating power and the power developed by the ventilation passage of steam into the condenser with the diaphragm of the low-pressure cylinder (hereinafter referred to as LPC) completely closed. Factors that increase beyond the minimum required level (leakage of the control diaphragm of the low-pressure cylinder, increase in the temperature of the exhaust pipe above permissible level etc.) are confirmed by relevant documents. The calculation of the minimum load of the thermal power plant is carried out in accordance with the recommendations given in Appendix 14 to this Instruction.

  Additional condensing electricity generation to be distributed between turbines (*), thousand *, is determined by the formula:

  where E is the planned electricity generation, thousand *

  For CHP plants, when justifying additional condensing electricity generation, the following factors can be considered:

  presence of non-switched-off heat supply consumers;

  ensuring a technical minimum boiler load;

  increasing the temperature of cooling water at the outlet of turbine condensers to prevent freezing of cooling towers in winter.

  Distribution * between turbines is made on the basis of pre-calculated characteristics of relative increases in heat consumption for electricity generation through the condensation cycle (*) for all possible combinations of units. The units with the smallest * values ​​are loaded first.

  The distribution of heat supply to external consumers in steam of the same pressure or with network water between the subgroups of the power plant is carried out in proportion to the thermal loads of the turbine extractions (*, *) included in the subgroup.

  Heat supply from peak hot water boilers is distributed among subgroups of power plant equipment in proportion to heat supply with network water.

  The values ​​of hourly flow rates of fresh steam (*) and steam to condensers (*) for individual turbines necessary for calculations can be calculated with sufficient accuracy for forecasting purposes using the formulas, t/h:

  where * is the initial nominal specific gross heat consumption of the turbine, kcal/*;

  K - coefficient of ratio of heat consumption and fresh steam to the turbine can be taken equal to 0.6-0.7 or calculated using the formula:

  where *, *, * are the enthalpies of fresh steam, feed water, the increase in enthalpy in the reheating path, kcal/kg;

  * — share of reheat steam from fresh steam consumption;

  * — electromechanical efficiency, %. Taken equal to 97%;

  * — heat loss through the turbine insulation, Gcal/h. For turbines with a capacity of 25.50 and 100 MW, 0.49 can be taken; 0.61 and 1.18 Gcal/h.

  When calculating the NUR, the parameters of fresh steam and steam after reheating correspond to the values ​​​​accepted as nominal in the regulatory characteristics of turbines.

  23. For thermal power plants using the method of distributing fuel costs in a combined cycle between electrical and thermal energy in proportion to the heat costs for generating electrical energy and supplying thermal energy, provided they are produced separately, an increase in heat consumption for electricity production with the conditional absence of heat supply to external consumers from the selections and turbine back pressure (*), Gcal, is determined by the formulas:

  for turbines type PT, T: *, (9)

  for turbines type P, PR: *, (10)

  where *, * are the specific gross heat consumption of the turbine in the absence of heat supply from the extractions (pressure regulators in both extractions (on) and with a predicted electrical load, kcal/*;

  * - specific heat consumption for a turbine with a condenser, which has the same parameters of fresh steam as for turbines of type P, PR at a predicted electrical load in the absence of heat release from the extractions (pressure regulators in the extractions are turned on), kcal/*;

  * — predicted electricity generation by the turbine, thousand *;

  * - ratio for the subgroup of heat supply to external consumers using exhaust steam to the total load of extractions.

  For turbines with steam condensation, when heat is released from the condenser due to a “deteriorated” vacuum, the value of * can be taken equal to the amount of heat released from the condenser.

  The ultimate goal of performing calculations for a turbine installation is to obtain predicted values ​​for subgroups of equipment:

  absolute and specific gross heat consumption for electricity generation (*, Gcal and *, kcal/*);

  absolute and specific consumption of heat (*, Gcal and *, %) and electricity (*, thousand * and *, %) for own needs;

  net specific heat consumption *, kcal/*.

  24. The number of boiler units of each type (*) operating in the group during the forecast period is selected based on the total heat demand for turbines, the load of boiler units at the level of 80-90% of the nominal heating capacity, as well as the equipment repair schedule. Agreed limitations on the nominal steam output of boiler units are also taken into account.

  The total gross heat production of a boiler installation of a subgroup of equipment, Gcal, is calculated using the formula:

  where * is the specific value of heat flow losses, % is assumed to be equal to 1.5% of the nominal productivity of m-th type boiler units operating in the forecast period;

  * — number of operating boiler units of the mth type selected during the forecast;

  * — nominal heat output of the m-th type boiler unit, Gcal/h.

  The distribution * between the types of boiler units of a group of equipment is made in proportion to the rated heat output (if there are no other considerations at the power plant).

  The final results of the calculations are the following groups of equipment for boiler installations:

  absolute and specific consumption of heat (*, Gcal and *, %) and electricity (*, thousand * and *, %) for own needs.

  The values ​​of thermal efficiency reserve coefficients (*) are calculated based on the reporting data of the previous year for the month corresponding to the forecast:

  where *, * are the actual and nominal specific fuel consumption for supplied energy in the i-th month of the previous year;

  * — coefficient that takes into account the elimination of fuel burnouts due to deviations of equipment performance from the standard level.

  The value * is calculated as the ratio of fuel burnouts that are not planned to be eliminated in the next 2 years to the amount of fuel burnouts for the year preceding the forecast one. The value * is justified on the basis of a map of excessive fuel consumption and an action plan to eliminate them.

  The degree of use of thermal efficiency reserves (*) when calculating specific fuel consumption standards for the regulated period is taken equal to zero.

  Correction of the NUR values ​​calculated on the basis of the normative and technical documentation for fuel use (*), the indicators of which are worse than the actual values ​​of the indicators in the year preceding the calculation year, is carried out according to the formula:

  where * is the correction factor:

  *, * - respectively, actual and nominal values ​​of specific fuel consumption for supplied electricity and heat according to reporting data for each month of the year preceding the calculated one.

  Calculation of NUR based on reporting data of the base period

  25. Calculation of the NUR based on the indicators of the base period is carried out in the absence of current regulatory and technical documentation on fuel use at the TPP.

  One of the two years preceding the calculated one, differing in the volumes of electricity generation and heat supply from the calculated one by no more than 10%, can be taken as the base period. If both previous years meet this condition, then the Last year, preceding the calculated one.

  Depending on the method used at thermal power plants for distributing fuel costs by power boiler units between electrical and thermal energy, the calculation of the NUR is carried out in accordance with the formulas given below. The subscript “b” in the designation of indicators included in the formulas means that they belong to the base period.

  Method for distributing fuel costs of power boiler units between electrical and thermal energy using separate production indicators

  26. Power plants that use the method of distributing fuel costs by power boiler units between electrical and thermal energy using separate production indicators, calculate the NUR for supplied electricity, g/*, using the formulas:

  where *, * is the actual specific fuel consumption for electricity and for separate production, g/(*);

  * — amendments to specific fuel consumption for changes in the values ​​of external factors in the forecast period compared to the base;

  * — coefficient of increase in fuel consumption of power boilers during separate production:

  *, * - heat supply to external consumers in total and from peak hot water boilers, Gcal;

  * — relative value losses, % associated with heat supply from power boilers;

  *, * — actual heat consumption for electricity production and for separate production, Gcal:

  * — increase in heat consumption for electricity production during separate production, Gcal;

  *, *, * - increase in heat consumption for electricity production in the conditional absence of heat supply to external consumers, respectively, from production and district heating extractions (as well as from equivalent unregulated extractions) and from turbine unit condensers, Gcal;

  Values ​​* and * for the forecast period are determined by the formulas:

  where *, *, * - heat supply to external consumers and for own needs, respectively, from production and district heating extractions (and equivalent unregulated extractions) and from turbine unit condensers, Gcal;

  * — average operating time of a single turbine unit over the forecast period, h;

  * — conditional idling heat consumption of the turbine unit of the i-th rated power value, Gcal/h. Determined by energy characteristics according to the graph of * at * and *;

  * — the number of turbine units of the i-th rated power value in operation;

  * — average relative increase in heat consumption for the production of electricity in the condensation cycle for turbine units with these parameters (with pressure regulators in regulated extractions turned on), Gcal/(*);

  E — electricity generation, thousand *.

  27. Predicted values ​​of specific fuel consumption standards for heat released “from collectors” (kg/Gcal) are calculated using the formulas:

  where *, * - specific fuel consumption for power boilers: actual and for separate production (does not take into account electricity costs for the heating plant), kg/Gcal;

  *, *, — absolute (t) and specific (kg/Gcal) consumption of equivalent fuel for peak hot water boilers;

  * — electricity consumption for a heating plant, thousand *;

  * — total consumption of equivalent fuel for heat supply, t;

  *, *- amendments to specific fuel consumption of power boilers and peak water boilers for changes in the values ​​of external factors in the forecast period compared to the base one, kg/Gcal;

  * — heat supply with hot water, Gcal.

  28. Using the formulas below, amendments to specific fuel consumption for the supply of electricity (*) and heat (*, *) are calculated when changing:

II. Methodology for calculating standards for creating fuel reserves for boiler houses

17. Standards for creating fuel reserves can be formed:

for the organization as a whole, if it is possible to use fuel reserves regardless of the territorial location of thermal energy sources and fuel storage warehouses;

for individual separate divisions (branches) by type of fuel;

for separate divisions (branches), geographically distant from other divisions of the organization.

18. The standards for creating fuel reserves for organizations and (or) their separate divisions (branches) in areas where the supply of fuel is seasonal are subject to separate calculations.

Standard for creating fuel reserves for specified organizations determined for the period until the next seasonal supply of fuel.

19. The estimated size of the NNZT is determined by the average daily planned fuel consumption of the coldest month of the heating period and the number of days, determined taking into account the type of fuel and the method of its delivery:

(thousand tons), (2.1)

where is the average value of heat supply to the heating network (boiler house output) in the coldest month, Gcal/day;

Estimated standard specific fuel consumption for supplied thermal energy for the coldest month, t.e./Gcal;

K is the coefficient of conversion of natural fuel into conventional fuel;

T - duration of the period of formation of the volume of irreducible fuel reserve, days.

20. The number of days for which the NZT is calculated is determined depending on the type of fuel and the method of its delivery in accordance with Table 1.

Table 1

Type of fuel	Fuel delivery method	Fuel reserve volume, days.
1	2	3
hard	railway transport	14
	motor transport	7
liquid	railway transport	10
	motor transport	5

21. To calculate the size of the NEZT, the planned average daily fuel consumption of the three coldest months of the heating period and the number of days are taken:

for solid fuel - 45 days;

for liquid fuel - 30 days.

The calculation is made according to formula 2.2.

(thousand tons), (2.2)

where is the average value of thermal energy supplied to the heating network (production by boiler houses) during the three coldest months, Gcal/day;

Calculated standard weighted average specific fuel consumption for supplied thermal energy for the three coldest months, t.e./Gcal;

T - number of days, days.

22. For organizations operating heating (industrial heating) boiler houses using gas fuel with reserve fuel, the NEZT additionally includes the amount of reserve fuel necessary to replace () gas fuel during periods of reduction in its supply by gas supply organizations.

The value is determined based on data on restrictions on gas supply by gas supply organizations during cold spells, established for the current year.

Taking into account deviations in actual data on restrictions from those reported by gas supply organizations for the current and two previous years, the value can be increased according to their average value, but not more than by 25%.

(thousand tons), (2.3)

where is the number of days during which the gas supply is reduced;

Proportion of daily fuel consumption to be replaced;

Deviation coefficient of actual gas supply reduction indicators;

The ratio of the calorific value of reserve fuel and gas.

23. NEZT for organizations for which fuel is imported seasonally (before the start of the heating season) is determined by the total planned fuel consumption for the entire heating period for its total duration.

The calculation is made according to formula 2.4.

(thousand tons), (2.4)

where is the average daily value of heat energy supplied to the heating network during the heating period, Gcal/day;

Weighted average standard specific fuel consumption for the heating period, t.e./Gcal;

T - duration of the heating period, days.

NZT for organizations for which fuel is imported seasonally is not calculated.

24. It is recommended to draw up the main initial data and results of calculations of standards for creating fuel reserves in accordance with Appendix No. 1 to this Procedure.

25. For organizations for which the production and transmission of thermal energy is not the main activity, the structure of the CGT includes:

NNZT, calculated based on the total heat load connected to the source;

NEZT, determined by the connected heat load of external consumers of thermal energy.

26. It is recommended that calculations of standards for the creation of heating (industrial heating) boiler houses be drawn up in accordance with Appendix No. 2 to this Procedure.

Approved

By order of the Ministry of Energy of Russia

dated 12/30/2008 N 323

PROCEDURE FOR DETERMINING STANDARDS FOR SPECIFIC FUEL CONSUMPTION IN THE PRODUCTION OF ELECTRICAL AND THERMAL ENERGY

I. General provisions

1. Specific fuel consumption is subject to normalization for:

released electrical energy from tires and thermal energy from collectors of thermal power plants operating on fossil fuels;

released thermal energy from boiler house collectors.

2. Specific fuel consumption standards are determined for each thermal power plant (hereinafter - TPP) and boiler house (with the exception of heating and industrial heating boiler houses in the housing and communal services sector).

The standard specific fuel consumption for supplied thermal energy by heating and industrial heating boiler houses in the housing and communal services sector is determined as a whole for the organization.

3. In this order, the standard specific fuel consumption (hereinafter referred to as NUR) is understood as the maximum permissible technically justified measure of fuel consumption per unit of electrical energy supplied from the tires, per unit of thermal energy supplied to the heating network. The standards are determined in grams of standard fuel per 1 kilowatt-hour (g equivalent fuel/kWh), kilograms of standard fuel per gigacalorie (kg equivalent fuel/Gcal), differentiated by month.

This procedure is applied when establishing the NUR for the next settlement period of regulation (financial year), as well as when establishing the NUR for each settlement period of regulation within the framework of long term regulation when setting long-term tariffs in the heat supply sector.

4. The primary objects of NUR calculations at thermal power plants with steam turbine units are groups and subgroups of equipment. An equipment group is a set of condensing turbine units or turbine units with adjustable steam extraction and back pressure (for power units also with the same power), as well as all boilers (both pulverized coal and gas and oil) that ensure the operation of these turbo units. The subgroup of power units includes a set of only pulverized coal or only gas-oil boilers and condensing or heating turbine units working together with them with the corresponding fresh steam pressure and the same power. A subgroup of cross-coupled equipment is a set of condensing or heating turbine units with the same parameters of fresh steam and boilers that ensure the operation of these turbine units and burn only solid or gas-oil fuel.

If pulverized coal and gas-oil boilers operate on a common fresh steam collector, then the subgroup of equipment with cross connections is conventionally considered pulverized coal.

For thermal power plants equipped with combined cycle gas units (hereinafter - CCGT) or gas turbine units (hereinafter - GTU), as well as diesel generators (hereinafter - DG), NUR calculations are performed for each piece of equipment.

The standard specific fuel consumption for the supplied thermal energy from the heating (industrial heating) boiler house (group standard) is calculated on the basis of individual boiler standards taking into account their productivity, operating time, the weighted average standard for the production of thermal energy by all boilers of the boiler room and the amount of thermal energy consumption for their own boiler room needs. Individual standard specific fuel consumption - standard consumption of the calculated type of fuel per boiler for the production of 1 Gcal of thermal energy under optimal operating conditions.

Thermal energy supplied to the heating network is defined as the thermal energy produced by the boiler units, minus the thermal energy used for the boiler house’s own needs, and transferred to the heating network.

5. For steam turbine and gas turbine thermal power plants with an installed electrical capacity of 10 MW or more and boiler houses with a heating capacity of 50 Gcal/h and above, NUR calculations are carried out on the basis of the normative and technical documentation (hereinafter - NTD) in force at the time of calculations for fuel use.

The composition of the normative and technical documentation for fuel use and the requirements for its development are given in Section II of this procedure.

For thermal power plants with a capacity of less than 10 MW and boiler houses with a heating capacity below 50 Gcal/h, as well as in the case of a temporary absence of normative documentation on fuel use or the expiration of its validity period at thermal power plants and boiler houses of higher capacity, it is allowed to use in calculations:

base period indicators;

data from manufacturers, typical energy characteristics of boiler and turbine units;

expert assessments based on reporting or other data.

For DG, passport, reference data and operational indicators are used in NUR calculations.

6. When calculating the NUR, additional fuel and energy costs caused by:

omissions in operational and repair maintenance of equipment;

carrying out construction, installation, experimental and research work;

commissioning and commissioning of new equipment;

preservation of units.

7. In the event that the actual values ​​of the indicators exceed the indicators of the energy characteristics of the equipment (in terms of the efficiency of boiler and turbine units, vacuum, feed water temperature, electricity and heat costs for own needs, etc.) in the year preceding the calculated one, the NUR values ​​calculated based on the normative and technical documentation for fuel use, are adjusted downwards by the amount of fuel savings compared to the energy characteristics obtained in the previous year.

8. The selection of the composition of operating equipment and the distribution of electrical and thermal loads between individual units of power plants and boiler houses are based on the principles of ensuring reliable energy supply to consumers and minimizing fuel costs for energy supply.

9. NUR calculations are carried out for each month of the settlement period of regulation (long-term regulation period) and in general for the entire settlement period of regulation (each settlement period within the long-term regulation period). The NUR as a whole for the settlement period of regulation is determined based on the results of calculations for each month.

10. The distribution of fuel costs by power boilers between electrical and thermal energy generated in the combined cycle at thermal power plants in NUR calculations is carried out in accordance with the methods adopted in the preparation of state statistical reporting.

11. The documents substantiating the values ​​of the standards considered by the Russian Ministry of Energy for electric power plants and boiler houses include:

a summary table of the results of calculations of specific fuel consumption standards for supplied electricity and heat, prepared in accordance with Appendix 1 to this procedure;

II. Composition of regulatory and technical documentation on fuel use of steam turbine, gas turbine thermal power plants and boiler houses and requirements for its development

12. Regulatory and technical documentation on fuel use is developed for steam turbine and gas turbine thermal power plants with an installed electrical capacity of 10 MW or more and boiler houses with a heating capacity of 50 Gcal/h and above.

13. The regulatory and technical documentation for the fuel use of a thermal power plant includes:

energy characteristics of boiler units of each equipment group;

energy characteristics of turbine units of each equipment group;

dependence of technological heat losses associated with heat supply for each group of equipment;

dependence of the absolute or specific costs of electricity and heat for the auxiliary needs of each group of equipment and the power plant as a whole;

explanatory note on the development of energy characteristics of equipment and dependencies of electricity and heat costs for own needs;

graphs of initial nominal specific fuel consumption for supplied electricity and heat;

models for calculating the nominal parameters of equipment and specific fuel consumption standards;

reporting data on nominal and actual specific fuel consumption for the last 3 years preceding the development of normative and technical documentation for fuel use.

graphs of initial nominal specific fuel consumption for supplied heat;

layout for calculating nominal indicators and specific fuel consumption standards;

a plan of organizational and technical measures for the implementation of thermal efficiency reserves and the rational use of fuel and energy resources, developed on the basis of mandatory energy surveys;

Regulatory and technical documentation on fuel use of organizations operating heating (industrial heating) boiler houses includes:

energy characteristics of boilers;

characteristics of the fuel used;

operating maps developed based on the results of operational testing;

calculations and indicators of heat consumption for the boiler house’s own needs for the accounting year;

a plan of organizational and technical measures for the rational use and saving of fuel and energy resources and the reduction of specific fuel consumption standards;

reporting data on nominal and actual specific fuel consumption for the last 3 years preceding the development of normative and technical documentation for fuel use.

14. The energy characteristics of the unit (hereinafter - ECH) is a complex of dependencies of the nominal and initially nominal values ​​of parameters and performance indicators in absolute, specific or relative terms on the load or other standard-forming indicators at fixed values ​​of external factors.

The EC is developed for a specific thermal circuit of a technically sound unit, taking into account its design features, operating conditions and modes, and service life.

EC reflects the maximum possible efficiency of use of energy resources by the unit, provided there are no omissions in its operation, maintenance and repair.

The EC includes a system of corrections that makes it possible to assess changes in the volume of energy consumption by the unit when external factors change and the deviation of the actual values ​​of parameters and indicators from the parameters and indicators of the EC.

External factors include objective factors that influence the efficiency of equipment operation, the values ​​of which do not depend on the activities of production personnel and contract repair organizations.

The following are used as initial data when developing EC equipment:

results of representative balance tests;

data from commissioning or express tests;

Balance tests are performed on equipment that has undergone a major overhaul and has higher operational values ​​of thermal efficiency indicators compared to other equipment of the same type at a thermal power plant or boiler house.

In the absence of test results and technical characteristics, the best performance indicators or data from equipment manufacturers can be used as initial data for the development of temporary electrical characteristics with a validity period of no more than 1 year.

15. When developing EC, with appropriate justification, it is allowed to take into account the accuracy of the source material used in the development of energy characteristics, aging (wear) of equipment, and the presence of irreparable defects in design, manufacturing and installation. The operational tolerance, due to its objectivity, is taken into account without additional justification, since it reflects a deterioration in the efficiency of equipment during the period between repairs.

The accuracy of the source material reflects the errors of thermal tests and typical energy characteristics.

Aging (wear) of equipment characterizes the natural physical wear of equipment that is technologically unrecoverable by repairs during its long-term operation, leading to a deterioration in technical condition, a decrease in efficiency and operational reliability.

16. Amendments for changes in parameters and indicators provided as part of the energy characteristics of equipment provide:

determination of nominal values ​​of parameters or indicators with actual or predicted values ​​of external factors;

assessment of the thermal efficiency reserve of equipment due to deviation of the actual value of a parameter or indicator from its nominal value.

17. Graphs of initial nominal specific fuel consumption are calculated and plotted:

for each group (subgroup) of power plant equipment for winter and summer periods with characteristic combinations of operating equipment, average heat output values ​​in the real range of changes in electrical loads;

for steam and hot water boilers of a boiler room for characteristic combinations of operating boilers in the real range of changes in thermal loads.

The graphs indicate:

parameters, conditions and values ​​of external factors under which the graphs were constructed;

amendments to specific fuel consumption for changes in external factors and conditions;

combinations of operating units;

fuel losses during equipment startups from various thermal states;

values ​​of thermal efficiency reserve coefficients for the supply of heat and electricity and the degree of their use.

18. The layout for calculating nominal indicators and specific fuel consumption standards is a table reflecting the calculation procedure, defining the sources of primary information and containing calculation formulas.

Layouts are developed by groups (subgroups) of equipment, taking into account the composition of the equipment and the features of its thermal circuits, operating modes, and types of fuel burned.

Layouts reflect:

initial nominal values ​​of indicators determined by energy characteristics (without amendments) at actual average loads. The performance of turbine units is determined for each of their operating modes (condensing, with one or two controlled steam extractions, with one- or two-stage heating of network water);

actual values ​​of external factors, indicators characterizing energy production volumes, equipment operating modes, startups;

the values ​​of amendments to indicators for the difference between the actual values ​​of external factors and those adopted when constructing energy characteristics;

nominal values ​​of the main and intermediate indicators of units for actual operating modes and values ​​of external factors;

values ​​of amendments to specific fuel consumption for stabilization of regimes, development of newly introduced equipment;

specific fuel consumption standards.

19. The validity period of the normative and technical documentation for fuel use cannot exceed 5 years. Upon expiration of the validity period of the NTD, it is revised; the validity period of the NTD is not extended. The regulatory document is revised quarterly before the end of its validity period.

An extraordinary revision of the technical documentation is carried out when:

converting boilers to burn fuel of a different type or brand;

transferring turbine units with steam condensation to operation with back pressure or deteriorated vacuum;

reconstruction of turbine units with the organization of controlled extraction or with an increase in the release of steam from the controlled extraction;

introduction of new equipment.

20. Calculation of the minimum load of thermal power plants
21. It is recommended to calculate the minimum load of a thermal power plant in the following sequence:
22. 1. Calculation of heat supply to consumers in steam and hot water is carried out (conversion of weight costs and temperatures into heat).
23. 2. Heat supply (including economic needs) is preliminarily distributed among heat supply sources (turbine extractions, PVC, ROU) based on the condition that ROU and PVC are not put into operation until the possibilities for heat supply from turbine extractions have been completely exhausted.
24. 3. The minimum composition of the equipment is preliminarily determined, the heat consumption for its own needs (in steam and hot water) is calculated, and the technological losses during heat supply by power and peak water boilers are determined.
25. 4. The total heat demand (external consumers, economic and own needs, technological losses) is finally distributed between heat supply sources.
26. (pre) 5. The thermal load of the extractions is distributed between the turbine units. Their number should be minimal, the steam flow into their condensers should be equal to the minimum according to the manufacturer. Based on the energy characteristics, the standard power of each turbine unit (N) is determined for the mentioned conditions (n). m i 6. The relative increase in heat consumption for electricity production through the condensation cycle at a given thermal load is determined for each turbine unit - Deltaq. book i 7. Corrections (DeltaN) to the initial power of each m ij turbine unit are calculated for the deviation of the predicted values ​​from those accepted when constructing the energy characteristics (mode diagrams): (/pre)
