8.2. Calculations for each source of thermal energy of standard stocks of emergency fuels Information on stocks of emergency fuel is presented in Chapter 1, Part 8, clause 8.2 of the Justifying Materials for the Heat Supply Scheme.

Calculation of the standard reserves of emergency fuels is carried out on the basis of the order of the Ministry of Energy of the Russian Federation dated 04.09.2008 No. No. 66 "On the organization in the Ministry of Energy of the Russian Federation of work on the approval of standards for the creation of fuel reserves at thermal power plants and boiler houses." According to it, the standard for the creation of fuel reserves at thermal power plants and boiler houses is the total standard stock of the main and reserve fuels (hereinafter - ONZT) and is determined by the sum of the volumes of the irreducible standard fuel stock (hereinafter - NNP) and the standard operational fuel stock (hereinafter - NEZT) .

Calculation method:

1. Estimated amount of NNCT 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:

where: Q max - average value of heat energy supply to the heat network (boiler house output) in the coldest month, Gcal/day;

H SR.T - the calculated standard of specific fuel consumption for the supplied thermal energy for the coldest month, tce/Gcal;

To- coefficient of conversion of natural fuel into conditional;

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

2. The number of days for which the NNCT is calculated is determined by the actual time required for the delivery of fuel from the supplier or base warehouses, and the time required for loading and unloading operations (table).

3. For boiler houses operating on local fuels, NNCT is not established.

4. To calculate the amount of 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.

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

H SR.T - the calculated standard of the weighted average specific fuel consumption for the supplied thermal energy for the three coldest months, kg of fuel equivalent/Gcal;

T- the number of days.

5. For organizations operating gas-fired heating (industrial and heating) boiler houses with reserve fuel, the NEZT includes the amount of reserve fuel required to replace ( AT ZAM) gas fuel during periods of reduction of its supply by gas supply organizations.

Meaning AT ZAM is determined on the basis of data on the limitation of gas supply by gas supply organizations during the cold weather period established for the current year.

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

where: T ZAM - the number of days during which the gas supply is reduced;

d ZAM - the share of daily fuel consumption to be replaced;

To ZAM - coefficient of deviation of the actual indicators of gas supply reduction;

To EKV - the ratio of the calorific value of the reserve fuel and gas.

6. NERT 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 the formula:

where: Q СР - the average daily value of the supply of thermal energy to the heating network during the heating period, Gcal / day;

H SR - weighted average standard of specific fuel consumption for the heating period, tce/Gcal;

T- duration of the heating period, days.

Fuel reserves

Humanity now uses as much fuel per year as has been stored on the planet for millions of years.

The level of fuel consumption can be judged on the level of well-being of the country. On average, one person on Earth consumes about 5 kg reference fuel (cf) per day, in industrialized countries - about 30 kg c.u. per day. The total fuel consumption in the world is about 12 billion tons of standard fuel (tce) per year.

According to the latest data from the World Energy Council (WEC), the fossil fuel reserves in the world amount to 1220 billion tons of fuel equivalent, and the total recoverable fuel reserves are 4–5 times more, i.e. sufficient for world demand for many decades (up to 500 years).

Consumption and explored fuel reserves in the world are given in Table. 1.1.

Table 1.1 - Consumption and fuel reserves

An expert, optimistic assessment of the possible amount of fuel in the bowels of the Earth according to the data is given in Table. 1.2.

Table 1.2 - Estimation of the amount of fuel in the bowels of the Earth and the stock at current consumption

The most important problem for every country is its energy supply.

In table. 1.3 presents data on the provision of Ukraine with its own energy resources according to the data.

Table 1.2 - Provision of Ukraine with its own energy resources

Ukraine belongs to the countries with a deficit of its own natural hydrocarbon resources. Ukraine produces about 94 million tons of fuel equivalent of its own fuel. per year, and the need for a normal state of the economy is about 300 million tons of fuel equivalent. in year. The need for imports is about 206 million tce, including natural gas - 138 million tce. (120 billion m 3), oil - 68 million tons of fuel equivalent. (50 million tons).

In Ukraine, the structure of consumption of primary energy resources looked like this in recent years:

Natural gas - 43%;

Oil - 18%; (gas + oil - 61%);

Coal - 23%;

Nuclear energy - 16%.

Coal deposits in Ukraine:

Donetsk coal basin of the Luhansk region (coal of all grades).

Lviv-Volynsky coal basin (coal grade G).

Natural gas fields: Dashavskoye, Shebelinskoye, gas field in Gogolevo.

Due to the shelf of the Black and Azov Seas, it is planned to increase oil and gas production.

Taking into account the advanced world experience, important and promising for Ukraine is:

Increasing coal production to replace oil and natural gas;

Use of energy-saving industries and technologies;

Safety of existing nuclear units and obtaining own nuclear fuel, analysis of the possibility of building new NPP units;

Search and production of new types of fuel from vegetable raw materials, technical alcohols, etc.

NEZT is necessary for the reliable and stable operation of the boiler house and ensures the planned generation of thermal energy in the event of restrictions on fuel supplies.

NEZT is determined in accordance with paragraph 23 of the “Procedure for determining the standards for fuel reserves at sources of thermal energy (with the exception of thermal energy sources operating in the mode of combined generation of electric and thermal energy) of the Order of the Ministry of Energy of the Russian Federation No. 377 dated August 10, 2012 for the total planned consumption fuel for the entire heating period according to its total duration.

The calculation is made according to the formula:

where: Qav – average daily value of heat energy supply to the heat network during the heating period, Gcal/day;

Н av – weighted average standard of specific consumption of standard fuel for supplied thermal energy, for the heating period, kg of reference fuel/Gcal;

T is the duration of the heating period, days;

K - caloric equivalent, adopted in accordance with the "Methodology for determining the need for fuel, electric energy and water in the production and transmission of thermal energy and heat carrier in public heating systems", approved by the State Construction Committee of Russia on August 12, 2003, K coal \u003d 0.7143;

The results of NERT calculation are summarized in Table 3

40. For organizations operating gas-fired heating (industrial and heating) boiler houses with reserve fuel, the NEZT includes the amount of reserve fuel necessary to replace (V_zam) gas fuel during periods of reduction in its supply by gas supply organizations.

The value of V_zam is determined according to the data on the limitation of gas supply by gas supply organizations during the period of cold weather, established for the current year.

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