Blast-Furnace Gas | Article about Blast-Furnace Gas by …
Blast-furnace gas is utilized as a fuel in metallurgical works. The heat of coustion of blast-furnace gas is approximately 3.6–4.6 megajoules per cu m (850–1,100 kcal per cu m). When the blast is enriched with oxygen, the nitrogen content of the gas is lowered and the amount of other gases (including carbon monoxide and hydrogen), as well as the heat of coustion, increases correspondingly.
