How to calculate the equivalent amount of standard coal
Thread Content
As the title suggests, how is the equivalent amount of standard coal for different substances calculated?
The calorific value of different substances is converted to the calorific value of standard coal.
When converting electricity to standard coal, 1 unit of electricity is equal to 1 KWh. 1 W = 1 J/s. The thermal value of 1 unit of electricity, that is, the energy produced by electricity over 1 hour, is: 1000 W × 3600 s = 3,600,000 J. In China, it is specified that the thermal value of 1 kg of standard coal is 7000 kcal, with 1 cal equal to 4.18 J. Therefore, the energy produced by 1 gram of standard coal is: 7000 cal × 4.18 = 29,260 J. The mass of standard coal equivalent to 1 unit of electricity is: 3,600,000 J / 29,260 J/g = 123.03 g
