What formula is used to convert various energy consumption to standard coal?

Standard coal, with its unified calorific value of 7,000 kcal/kg, is used to measure the calorific value of different energy types and contents. To convert non-standard energy into standard coal, it is necessary to calculate the ratio of its actual calorific value to the calorific value of standard coal, that is, the energy conversion coefficient of standard coal. The formula for calculating this coefficient is: standard coal energy conversion coefficient = real calorific value of a certain energy (kcal/kg)/7000 (kcal/kg).

References for conversion coefficients have been given for different types of energy. For example, the conversion coefficient of raw coal is 0.7143 kg of standard coal/kg, and that of crude oil is 1.4286 kg of standard coal/kg. kg. Before switching to standard coal, it is first necessary to determine the average low calorific value of the coal.energy, then convert based on this value and the standard of 7,000 kcal/kg.

For heat conversion, it must be calculated based on the temperature, pressure and enthalpy of the steam or hot water generated by the boiler. If there is no detailed data, you can refer to the estimate. given method. The heat unit “kilocalorie” must then be converted to “standard tons of coal”, calculated on the basis of 7,000 kcal per tonne converted to 1 kilogram of standard coal. There are two methods of calculating the calorific value of electricity. The theoretical calorific value is 0.1229 kilograms of standard coal per kilowatt hour of electricity. In actual use, it can be converted according to the coal consumption of thermal power generation. The average value from the National Bureau of Statistics is 0.404 kilograms of standard coal per kilowatt hour of'electricity.

In general, through these coefficients and formulas, we can effectively convert various energy consumptions into unified standard coal units for easy management and comparison. In actual operation, calculations should be made based on the actual situation of specific energy sources and standard coal conversion requirements.

There are generally two methods for calculating the calorific value of electricity:

One is to calculate the calorific value according to the theoretical calorific value and the theoretical calorific value. is calculated based on the thermal work equivalent per kilowatt hour of electricity. 860 kcal corresponds to 0.1229 kilograms of standard coal.

One is calculated based on coal consumption for thermal energy production, which varies every year. To facilitate comparison, the National Bureau of Statistics usesse 0.404 kilograms of standard coal per kilowatt hour as standard coal conversion. coefficient for electricity in the future.

54,000 kilowatt hours: 54,000*0.404/1,000 = 21.82 tons of standard coal

The value of the coal/coke ratio is: per kilogram of coke converted to standard coal : 0.9714 kg of standard coal/kg, 8,800 tons is equivalent to 8,548.32 tons of standard coal

The low calorific value of standard coal is 7,000 kcal or 29.271 megajoules, then the two above items add up to 8,571 tons and the energy consumption of standard coal is 5,999.1 ten thousand kcal or 258,800 megajoules.

This is a Shenma product. It uses so much coke and so little electricity and water. Do you use an electric bellows to burn charcoal?

Energy consumption per unit of product: electricity consumption is 0.404 degrees, which is equivalent to 0.2474 coal standard.

The water consumption is 0.084 cubic meters, which is equivalent to 11.904 standard coal.

The coke consumption is 0.9714 t, which is the equivalent of a standard coal: 1.0294
