Types and characteristics of coal: 6. Gas coal composition and use

Mondo Finance Updated on 2024-01-29

Gas coal is a special coal resource, which is characterized by high volatile matter and thick colloidal layer. However, this coal has poor thermal stability, so care needs to be taken to control the temperature and time during use to avoid its unstable combustion or excessive harmful gases. Understand the types and characteristics of coalAlthough gas coal can coke alone, the quality of coke produced is not ideal. Due to its thick colloidal layer, the coke produced is slender and brittle, with large shrinkage and many longitudinal cracks. This makes gas coal coke less resistant to crushing and wearing, and therefore unsuitable for demanding metallurgical or chemical production. However, these shortcomings of gas coal do not mean that it is not valuable. In fact, gas coal plays an important role in coal blending and coking. By combining with other coal varieties, gas coal can improve the efficiency of coking and the quality of products. In addition, gas coal can be used for oil refining, gas production, nitrogen fertilizer production, or as a power fuel.

Industrial analysis and testing instruments for coal.

In oil refining, the volatiles in gas coal can promote the generation and purification of oil products. In the production of coal gas, gas coal can react with water vapor to produce gases such as hydrogen and carbon monoxide, which are used in chemical and metallurgical fields. In the production of nitrogen fertilizer, gas coal can be used as one of the raw materials to produce ammonia and other fertilizers through specific chemical reactions. As a power fuel, gas coal can be burned to produce heat that propel equipment such as steam turbines or internal combustion engines.

In short, although gas coal is not effective in coking alone, it has a wide range of application prospects in coal blending and coking, oil refining, gas production, nitrogen fertilizer production or as power fuel. When using gaseous coal, it is necessary to take corresponding measures according to its characteristics to ensure its combustion stability and reduce the generation of harmful gases.
