Coal for semi-coke production
Thread Content
Bituminous coal (QM), coking coal (]M), 1/3 coking coal (1/3]M), weakly caking coal (RN), long-flame coal (Cy), non-caking coal (EN). As we all know, semi-coke is essentially bituminous coal. I would like to ask the experienced professionals in this field: which of the above coal types can be used to produce semi-coke? And why? Why can’t coal types that cannot be used for burning lump charcoal be used? Thank you for the knowledge! ~~
Long-flame coal works fine; our company uses long-flame coal. But I don’t know exactly why either.
It is mainly weakly caking or non-caking long-flame coal, which belongs to low-grade bituminous coal and cannot be used for coking. Coking coal has better quality, and no one uses coking coal to produce semi-coke
Bituminous coal (QM), coking coal – 1/3 of coking coal cannot be used in the production of semi-coke. There are two reasons: one is waste. Second, it has adhesiveness, which hinders material discharge.
Long-flame coal, weakly caking coal, and non-caking coal can be used in the production of semi-coke!
What is the specific relationship between tar quality and semi-coke quality and coal quality?
Are vertical furnaces still used for producing lignite coke in China at present? I would like to ask how gas and tar generated during production are handled? Is there an introduction to the subsequent production processes?
