Experimental and numerical exploration of a new application of coal

Coal slag is a byproduct discharged from burning coal in thermal power plants, industrial and civil boilers, and other equipment. Coal accounts for about 50 wt% of the power production in China and 37 wt% in the world (Tang et al., 2015; Zhang et al., 2021). Therefore, a massive residue is produced during coal consumption annually.

Coal vs Slag: Do These Mean The Same? How To Use Them

One of the most common mistakes people make is using the terms "coal" and "slag" interchangeably. While both are byproducts of the combustion of coal, they are not the same thing.
