why does coal burn - Lisbdnet.com
Why Does Coal Burn? "Unlike timber, coal when it gets hot has massive thermal mass which is very hard to extinguish. …. Coal, and particularly brown coal, is very reactive to oxygen, and will generate CO2 and that creates heat. As the coal gets hotter it will eventually get to flame temperature and that coal will burn."Feb 14, 2014.Đọc thêm

Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.Đọc thêm
