42 MW Blast furnace gas boiler in Thailand - WHGLA

Blast furnace gas - Wikipedia. Blast 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 (3.5 MJ/m 3), because it consists of about 60 percent nitrogen and 18-20% carbon dioxide, which are not flammable.

Electroslag amp; Electric Arc Furnace Processes

2020-3-20 · The furnace was powered by a 1,000-kva transformer, with six voltage taps ranging from 100 to 215 volts. Subsequent tests were conducted in a nominal 0.9-metric-ton (1-ton) capacity tiltable, three-phase ac electric-arc furnace, lined with magnesite brick. The larger furnace was used so that a deeper bath could be achieved.

How does the blast furnace work? - SchoolScience.co.uk

2014-6-13 · How does the blast furnace work? The energy costs of the operation are kept to a minimum by collecting and cleaning the hot gas that leaves the furnace. This gas contains a lot of carbon monoxide. It can be re-used as a fuel for other steelmaking processes or to heat up the air blast to the furnace.
