“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.”
