It is widely use nature gas as combustion agent of multi-functional oxygen – burning (MFB) in foreign, due to its high Calorific value and good effect of heat compensation.The oxygen-COG(coke oven gas) multi-functional oxygen – burning is good use since it was self-designed by Panzhihua steel works and Metallurgical lance Institute in 2000. During the years of introduced RH-MFB technology, it was found that inner mixed burner would cause very loud noise and temper. In order to improve burner performance, preheating burner with no-noise and no-temper was independently designed, and in good effect use of. Ke
