I recently purchased a combustion analyzer for use working in the HVAC field; however, I had only a basic idea of how to use the meter: this book was very helpful in understanding the principles of combustion analysis and helping me put the meter to use in the field as a tool for troubleshooting and tuning gas fired appliances/5(10). This paper studied the combustion of blast furnace gas in a porous media burner. A numerical model method was established to analyze the combustion characteristics of blast furnace gas and solved by using the finite volume method. The temperature distribution, the position of the ignition, the flame structure, the recirculation zone and the concentration of the fuel were analyzed in the : Jinqiao He, Zhengchun Chen, Xin Jiang, Chun Leng. Lean Gas Burner ArcelorMittal Bremen GmbH, Steel Plant (Germany) Thermal utilization of lean gas instead of burning it off Burning off lean gases with a low heating value was a typical picture of steel plants in the past. They generate large volumes of gases with a low heating value, like blast furnace gas, as a by-product of steel smelting. The gas produced by this reaction moves up the furnace shaft which has been charged with ores, fluxes and coke. After a number of chemical reactions as described below and a travel of around 25 m to 30 m the BF gas comes out of the furnace as a heated, dust laden and lean calorific value (CV) combustible gas.
About 25 % of the blast furnace gas obtained is used for the cowpers /4/. Country specific conditions have to be taken into account, e.g. one of the two Swedish iron and steel plants uses 46 % of the blast furnace gas produced and 18 % of the coke oven gas produced for combustion in cowpers /5/. Blast furnace gas has a lower. Blast Furnace and Process Description: Iron blast furnace is a vertical shaft, which is used to melt the iron ore and to produce hot metal by heat exchange and chemical burden charge consisting of iron oxide, flux and coke and it provides through the throat from the top of the furnace. 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 kWh/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. Coke oven gas can be injected at blast furnace tuyeres and is a better solution than burning it in a power plant. Direct reduction units can be developed to produced DRI for use in steel shops or.
Basically, the blast furnace is a countercurrent heat and oxygen exchanger in which rising combustion gas loses most of its heat on the. Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone. 5 The Combustion Process Combustion is a chemical reaction of rapid oxidation started by the correct mixture of fuel, oxygen and an ignition source. The chemical reaction for natural gas is: CH4 + 3O2 = Heat + 2H2O + CO2 + O2 Where: CH4 = 1 cubic foot of Methane Gas (Natural gas) 3O2 = 3 cubic feet of Oxygen Heat = BTU's of energy produced from the chemical reactionFile Size: KB. Blast furnace gas (BFG) is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic has a very low heating value, about 93 BTU/cubic foot ( MJ/m 3), because it consists of about 60 percent nitrogen and % carbon dioxide, which are not rest is mostly carbon monoxide, which has a fairly low heating value already and some . Chapter V. Hot-Blast Stoves In the third decade of the nineteenth century James Beaumont Neilson, who from plain beginnings had made for himself a distinguished position as a gas engineer and authority on matters of combustion, was consulted by a furnaceman as to the reason for the very unsatisfactory work of his furnace, particularly in summer.
