The main use of power coal in china:1 power generation coal: more than 1/3 of China's coal used to generate electricity, the current generation of the average coal consumption of standard coal 370g/ (kW * h) or so. The power plant using the calorific value of coal, the heat energy into electricity2) steam locomotive coal: accounts for about 2% of the power coal, the average coal consumption of the boiler is 100kg/ (10000 tons / km)
