Please explain the use of coal in various aspects!
The use of coal is very extensive, according to the purpose of its use for two main purposes: (1) power coal, (2) coking coal.
(2) coking coalAlthough our country is rich in coal resources, coking coal resources are relatively small, coking coal reserves account for only 27.65% of China's total coal reserves.Coking coal includes coal (13.75%), (3.53%) coal, coking coal, lean coal (5.81%) (4.01%), the other is divided into grades of coal (0.55%); non coking coal includes anthracite (10.93%), coal (5.55%), alkaline coal (1.74%) do not pay, coal (13.8%), coal (12.52%), brown (12.76%), natural coke (0.19%), not the grades of coal (13.80%) and grade of coal is not clear (1.06%).
5) living with coal: the number of living coal is also large, accounting for about 20% of fuel coal.6 metallurgical power coal: Metallurgical power coal is mainly used for sintering and blast furnace coal injection, the amount of less than 1% of the coal used for power.
2) steam locomotive coal: accounts for about 2% of the power coal, the average coal consumption of the boiler is 100kg/ (10000 tons / km).3) coal for building materials: accounting for more than l0% of the power coal, the largest amount of coal used in cement, followed by glass, brick, tile, etc..4 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, coal accounts for about 30% of the coal.
The main use of power coal in china:1) coal for power generation: more than 1/3 of coal in China is used to generate electricity, and the average power consumption is 370g/ (kW / h). The power plant uses the calorific value of coal to convert heat energy into electrical energy.
