What is the use of coal?

Coal is widely used. About one third of the coal in China is used for power generation, and the average coal consumption for power generation is about 370 grams of standard coal per kWh. Power plants use the calorific value of coal to convert thermal energy into electric energy. Domestic coal consumption is also large, accounting for about 23% of fuel coal. Coal is also an important raw material for metallurgy and chemical industry, which is mainly used for combustion, coking, gasification, low-temperature dry distillation, hydro-liquefaction, etc.

Coal is a non-renewable resource. Coal is a solid combustible mineral gradually formed by ancient plants buried underground through complex biochemical and physical-chemical changes. It is a solid combustible organic rock, which is mainly transformed from plant remains by biochemical and geological processes after burial. Commonly known as coal. China is the first country in the world to use coal.

Coal is a modern industry, whether heavy or light; It plays an important role in energy industry, metallurgical industry, chemical industry, machinery industry, textile industry, food industry and transportation industry. All kinds of industrial sectors consume a certain amount of coal to a certain extent, so some people call coal the "real grain" of industry.

China is one of the countries with the richest coal resources in the world, which not only has large reserves and wide distribution, but also has a complete range and excellent coal quality, providing extremely favorable conditions for China's industrial modernization. However, coal will release carbon monoxide, carbon dioxide, sulfur dioxide, smoke and dust during combustion, which will cause air pollution and do some harm to human body.
