The Significance Of Wide Application Of Blast Furnace Gas Burner

The Significance Of Wide Application Of Blast Furnace Gas Burner
With the enhancement of the environmental protection awareness of the whole people and the requirements of the national industrial policy of energy conservation and emission reduction, saving coke oven gas with high calorific value and high economic value and making full use of blast furnace gas with low calorific value have become an urgent issue for burner manufacturers. The blast furnace gas burner for tubular furnace uses the blast furnace gas as the heat source of the tubular heating furnace in the coking plant, which expands the application scope of the blast furnace gas and reduces the energy consumption. It can be widely used in the coking plant of iron and steel enterprises, and has good promotion value.

Blast furnace gas is the waste gas from the blast furnace of iron making, and is a by-product in the iron making process. In blast furnace, 3800~4000m3 dry blast furnace gas is usually produced for every coke cocoa consumed. The blast furnace gas directly drawn from the blast furnace contains a large amount of dust (up to 60~80g/m3), which can only be used after being regenerated. The dust content of various equipment is limited to: steam boiler below 500g/m3; Gas turbine below 1g/m3; Open hearth furnace, hot blast furnace and heating furnace 20~50g/m3; The coke oven is less than 10g/m3. Blast furnace is a huge consumer of fuel in iron and steel complex, and about 60% of the heat of its fuel is transferred to blast furnace gas. Therefore, full and effective utilization of blast furnace gas is of great significance for energy conservation in metallurgical industry.
Blast furnace gas is a kind of gas that has low combustion temperature rise and is difficult to burn. Preheating is required to make it reach a higher combustion temperature; It is also an effective technical measure to mix it with other gases with better combustion performance, such as coke oven gas.
