Meanwhile, the volume flow rate of flue gas for the former was greater than the latter. The experimental results obtained from a co-firing of BFG and COG fueled-boiler in a steel company showed that whether at a higher or lower boiler load, with gradually decreasing the amount of COG supply, flame instability (lift-off and blow-out) did not occur and the rate of CO emission was very low.Get Price
gas is used as fuel to the boiler. For Blast Furnace, CO gas is the major by-product. In such cases dual fuel fired boiler is more effective from economic and environment point of view. 2. WORKING PRINCIPLE OF OIL & BF GAS FIRED WATERGet Price
Boiler Circulation Analysis: A 250 [TPH] high pressure coal/Blast Furnace Gas fired boiler at a steel works was plagued with continuous furnace wall tube failures. Design Boiler was engaged to investigate the project. A circulation analysis of the boiler was undertaken using our in house boiler design software.Get Price
1/7/2011 · In the steel industry, the recovered waste blast furnace gas (BFG) was mixed with natural gas as an alternative fuel to curb the consumption of the natural gas . It was found that if 50% of the waste BFG that contained 28% carbon monoxide, and 72% nitrogenGet Price
The Peabody Blast Furnace Gas (B.F.G.) burner from Hamworthy Combustion Engineering has been designed for use in boilers, furnaces and fired heaters that utilise low calorific value gas as the main fuel. The burner is a volute plenum chamber, which the gas Get Price

Blast Furnace or Coke Oven Gas Fired Boilers. We offer single-drum and bi-drum type blast furnace gas (BFG)* boilers for the steel industry. Both packaged and site-erected options are available. The burners for these boilers are manufactured indigenously. A notable benefit of Thermax's proven design is its high reliability in spite of the Get Price
Blast furnace gas is produced during the iron oxide reduction in blast furnace iron making in which iron ore, coke and limestone are heated and melted in a blast furnace and is an indigenous process gas of the steelworks industry (Pugh et al., 2013 ). Blast furnace gas has a high carbon monoxide (CO) content and a low heating value, typical Get Price

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.Get Price
Four oil- and gas-fired steam boilers provide steam for electric power generation, and to drive steam turbine driven fans for Blast Furnace process air. Two of these boilers (Babcock and Wilcox Type FH) were first put into operation in 1965, and still reliably produce 100 tons/hour of steam at a pressure of 44 bar and a temperature of 410 C.Get Price

1/1/2010 · The blast furnace process is primarily used in the carbothermic reduction of oxides, such as iron, zinc, and lead. Most of the iron ore bodies commercially explored consist of iron oxides. Consequently, rich iron ore and/or iron oxide pellets formed from concentrate can be added directly to a blast furnace (see Iron Production ).Get Price
The boilers are sometimes required to fire blast furnace gas [BFG] (a low Calorific Value [CV] waste stream from the process), along with other fuels such as pulverised coal and coke oven gas. The combustion of these fuel sources can impose conflicting design objectives on the boiler designer which can be difficult to achieve.Get Price
