and construction applications. Blast furnace gas (BFG) is a byproduct of this steelmaking process. Flare Capture Boiler Creates Reliable, Useful Energy BFG has a very low heating value— about 100 Btu/cubic foot, or one-tenth the heating value of natural gas. BFG from the No. 7 Blast Furnace had been used as the primary fuel for three boilers

Blast Furnace gas generation and usage – IspatGuru

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. The rest is mostly carbon monoxide, which has a fairly low heating value already and some (2-4%) …

Blast Furnace, Coke Gas and Converter Gas for Power Production

Apr 23, 2015 · The energy content of this gas may equal to an energy export of around 1.2 M cal/ton (5GJ/ton) of hot metal, or approximately 30 % of the gross energy consumption in the blast furnace. This energy content can be utilized by recovering, cleaning, and storing the BF gas and using it as a fuel gas in the steel plant or in the boilers for the

This process consists of a coke-packed shaft furnace with 12 m in height and 2.5 m in inner diameter at tuyere level, and three plasma generators for air heating, which treats 45,000 ton of stainless steel dust per year. The dust is injected with hot blast from tuyeres and melted and reduced.

Steel Mill Commissions $63 Million Energy Recovery, Reuse

steel - steel - Basic oxygen steelmaking: More than half the world's steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel. The basic oxygen furnace (BOF) is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow oxygen through nozzles at

COMBUSTION IN MANUFACTURING INDUSTRY

A wide range of fuels are supported, including solid fuels such as coal, petroleum coke and biomass like wood chip and wood pellet, gaseous fuels such as natural gas, blast furnace gas (BFG) and other by-product gases, and liquid fuels such as heavy crude oil and solvent de-asphalting (SDA) pitch.

Capturing Waste Gas: Saves Energy, Lower Costs

Blast Furnace Gas. Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around 0.9kWh/Nm 3, which on its own is typically not high enough for combustion in a gas engine. There is the possibility to blend this gas with other off gases and you should contact your local Clarke Energy office to discuss in more depth.

Recovery Act: ArcelorMittal USA Blast Furnace Gas Flare

Typical fuels used for the cowpers are natural gas, coke oven gas and blast furnace gas. But also liquid fuels can be used which require different types of burner. In some countries (e.g. Sweden) a blend of coke oven and blast furnace gas is used as fuel /5/. In order to facilitate the combustion of blast furnace gas, dust removal is necessary
