Standardization coefficient for coking plants
Thread Content
Energy is generally divided into primary energy and secondary energy. Those that have not been processed or converted are called primary energy, such as coal and oil； Energy that has been processed or transformed is called secondary energy, such as gas and electricity. To facilitate comparison in terms of the amount of energy saved, it is converted into an equivalent value based on the amount of primary energy saved, with \"tons of standard coal\" being the common unit of measurement. So, what are the coefficients for converting the inputs, outputs, and energy-consuming substances in coking plants into standard coal?

Serial number, Material, Equivalent standard coal amount Serial number, Material, Equivalent standard coal amount 1. Concentrated coking coal (dry): 1.014 t/t; 7. Electricity: 0.404 kg/kW·h 2. Coke: 0.971 t/t; 8. Steam: 0.12 t/t 3. Coke oven gas: 0.611 kg/m3; 9. Compressed air: 0.036 kg/m3 4. Tar: 1.29 t/t; 10. Nitrogen: 0.047 kg/m3 5. Crude benzene: 1.43 t/t; 11. Blast furnace gas: 0.109 kg/m3 6. Water used in production: 0.11 kg/m3; 12. Others, e.g.: The calorific value of 1 ton of standard coal is 29.3076 GJ. The calorific value of 1 ton of coke is 29.3076 GJ × 0.971 = 28.4577 GJ. The calorific value of 1 m3 of coke oven gas is 29.3076 GJ × 0.611 = 17.9069 GJ

Could you give a specific calculation method?
The calorific value of 1 kg of standard coal is 29.306 MJ, while that of 1 ton of standard coal is 29.306 GJ – aren’t these the same thing? 1 ton = 1000 kg ； 1 GJ = 1000 MJ; the national standard uses \"tons of standard coal\" as the unit of measurement.
