Bituminous coal is divided into three categories; based on which two parameters is this classification done? What are the decomposition points respectively? Classification is done using Vdaf and Hdaf; 2% and 3% for Hdaf are the two boundary values, while 3.5% and 6.5% for Vdaf correspond to the two boundary values

Bituminous coal is also divided into 3 subcategories based on its volatile matter content and application: Bituminous coal No. 1, with a volatile matter content of 3.5% or less, is suitable for use as carbon materials and other high-carbon materials； Bituminous coal No. 2, with a volatile matter yield of more than 3.5%–6.5%, is the main raw material for producing synthetic gas ； Bituminous coal No. 3 with a volatile matter yield of over 6.5% can be used as fuel for blast furnace nozzles
Answer: Classification is based on Vdaf and Hdaf; 2% and 3% for Hdaf are the two boundary values, while 3.5% and 6.5% for Vdaf correspond to the two boundary values
