• Blast_furnace_gas abstract "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, 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. It is commonly used as a fuel within the steel works, but it can be used in boilers and power plants equipped to burn it. It may be combined with natural gas or coke oven gas before combustion or a flame support with richer gas or oil is provided to sustain combustion. Particulate matter is removed so that it can be burned more cleanly. Blast furnace gas is sometimes flared without generating heat or electricity.Blast Furnace Gas is generated at higher pressure and at about 100 °C (212 °F)-150 °C (302 °F) in a modern Blast Furnace. This pressure is utilized to operate a generator (Top-gas-pressure Recovery Turbine - i.e. TRT in short), which can generate electrical energy up to 35 kwh/t of pig iron without burning any fuel. Dry type TRTs can generate more power than wet type TRT.Auto ignition point of blast furnace gas is approximate 630 °C (1,166 °F)-650 °C (1,202 °F) and it has LEL (Lower Explosive Limit) of 27% & UEL (Upper Explosive Limit) of 75% in an air-gas mixture at normal temperature and pressure.Higher concentration of carbon monoxide makes the gas hazardous.".
