Understanding the Differences: Cooking Coal vs. Non-Coking Coal
a. Lower carbon content: Non-coking coal generally has a lower carbon content compared to cooking coal, typically ranging from 40% to 70%. b. Higher ash content: Non-coking coal has a higher ash content, which means it produces more ash residue when burned. This makes it less suitable for the production of coke.
