1. Blast furnace gasBlast furnace gas (BFG) is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron. It has a very low heating value, about 93 BTU/cubic foot, because it consists of about 60 percent nitrogen, 18-20% carbon dioxide and some oxygen, which are not flammable. The rest is mostly carbon monoxide, which has a fairly low heating value already.
