Coal Use For Electricity GenerationCoal Use by IndustryConverting Coal Into Gas and Liquids
Many industries use coal and coal byproducts. The concrete and stone industries burn large amounts of coal to produce heat. The steel industry uses coal indirectly as coal coketo smelt iron ore into iron to make steel. The high temperatures created by burning coal coke give steel the strength and flexibility needed for bridges, buildings, and autom...
