The poster suggests that you search the forum first before posting, as there are many resources on coal analysis in the forum’s analysis and information-sharing section. “Go take a look at the profile index post for the “plain” moderator. 1. http://bbs.hcbbs.com/thread-400293-1-1.html 2. http://bbs.hcbbs.com/thread-415130-1-1.html
A comprehensive analysis of coal includes industrial analysis, elemental analysis, calorific value determination, various coking tests, gasification index determination, as well as analysis of ash composition and ash melting point. In the central laboratory of the mining authority, these parameters are generally required to be measured ； For coal analysis, it is necessary to determine the calorific value, industrial analysis, and sulfur content; it is also advisable to measure the ash melting point and slagging tendency. If the coal ash is to be utilized, an analysis of its composition is as well required ； For the analysis of coking raw materials, in addition to determining the basic properties of coal such as ash content, volatile matter, and sulfur content, it is also necessary to assess its coking properties, including the resin index, Roche index, free expansion order, and dry distillation test.
Generally, it is required to determine ash content, calorific value, volatile matter, etc
The analysis parameters vary depending on the type of coal; for thermal coal, they mainly include moisture, ash content, sulfur, calorific value (heat output), and ash fusion point； Coking coal ash content, sulfur, volatile matter, moisture, caking property, etc
Our thermal coal mainly consists of total moisture, ash content, calorific value (heat output), volatile matter, sulfur, etc
