The features such as converter generates a large amount of high-temperature gases in oxygen blast smelting process, and converter gas has high temperature, flow is large, dustiness is many, toxic and explosive, when method gas recovery is not fired in employing, in furnace gas, the main oxides CO content of carbon on average accounts for 70%.When blowing simultaneously, due to the play row of the evaporation of iron under high temperature action, air-flow stir, a variety of causes such as the explosion of CO bubble and splash produces a large amount of stove dirt, its total amount is about the 1%-2% of metal charge, be about 10%--20Kg/t steel, stove dirt is mainly the dust such as FeO, Fe2O3, CaO, SiO2, and dustiness is about 80-150g/Nm3.Its particle diameter major part when furnace gas does not fire is 10
more than m, after furnace gas burning, then major part is 1
below m, trapping difficulty is large relatively.
Flue gas revolves mixed, collision, condensation, cohesion etc. through water smoke and sticks on flue pipe wall in traditional flue, on flue pipe wall, easily produce fouling, and the resistance adding flue is damaged, and reduces cooling and efficiency of dust collection.
