3) coal for building materials: about l0% of the power coal, the largest amount of coal used in cement, followed by glass, brick, tile and so on4 general industrial boiler coal: in addition to the thermal power plant and large heating boiler, the general enterprise and the heating of the industrial boiler model, large quantity and scattered, with coal accounts for about 30%.
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)
The use of coal is very extensive, according to the purpose of its use for two main purposes: (1) power coal, (2) coking coal
