Extended data:

The main elements that make up coal organic matter are carbon, hydrogen, oxygen, nitrogen and sulfur, and there are also very few elements such as phosphorus, fluorine, chlorine and arsenic.

Carbon, hydrogen and oxygen are the main organic matter in coal, accounting for more than 95%; The deeper the coalification, the higher the carbon content and the lower the hydrogen and oxygen content. Carbon and hydrogen are the elements that generate heat when coal is burned, and oxygen is the combustion-supporting element. When coal is burned, nitrogen does not generate heat, but is converted into nitrogen oxides and ammonia at high temperature and precipitated in a free state.

Sulfur, phosphorus, fluorine, chlorine and arsenic are harmful components in coal, of which sulfur is the most important. When coal is burned, most of the sulfur is oxidized into sulfur dioxide (SO2), which is discharged with flue gas, polluting the atmosphere, endangering the growth of animals and plants and human health, and corroding metal equipment; When high sulfur coal is used in metallurgical coking, it will also affect the quality of coke and steel. Therefore, the content of "sulfur" is one of the important indexes to evaluate coal quality.

There are few inorganic substances in coal, mainly water and minerals, and their existence reduces the quality and utilization value of coal. Minerals are the main impurities in coal, such as sulfide, sulfate and carbonate, most of which are harmful components.
