It mainly burns coal for power generation and heating, which involves both bituminous coal and anthracite, as well as low-end coal such as lignite and coal gangue, which can basically be eaten without being picky in technology. The largest consumption of coal is also in the power sector.
Coal is mainly used for pig iron smelting, and the available coal types are coking coal, injection coal and thermal coal. Coking coal and injection coal are mainly used as reducing agents for iron ore, and as the skeleton in the blast furnace, coking coal has an irreplaceable role. In addition, they provide the required energy throughout the smelting process, and the ratio can be adjusted according to the actual process.
The use of thermal coal, mainly used for firing bricks, ceramics, glass, lime and other building materials. High-end ceramic products and glass products are replaced by natural gas or other fuels.
As a raw material coal, it is the main way of clean utilization of coal. The main products of traditional coal chemical industry are synthetic ammonia, urea, methanol, melamine, methylamine, DMF and so on.
After coal goes through various transformations, it can be natural gas, methanol, olefin, BDO (1, 4-butanediol), polyethylene, it can be a piece of plastic, a piece of clothing... All this, thanks to the rapid development of coal chemical industry.
China is rich in coal, poor oil, less gas, the use of coal more than this, I believe that in the future clean use of technology, coal will continue to play the role of energy "stabilizer" and "ballast stone".
