COKE FLAME CUPOLA FURNACE

The utility model discloses a coke flame cupola furnace which is a device for smelting cast iron by burnt coal. The coke burning chamber of the cupola furnace is separated from the body of the cupola furnace. The coke flame cupola furnace adopts the overfire iron melt of flames which lightly have reducibility to melt iron blocks, which reduces the ratio of the burnt areas of elements. Cokes are not in the cupola furnace, so carbon monoxide in furnace gas and carbon dioxide which is created after air enters from a secondary air nozzle is burnt can not generate reduction reaction with the cokes. Thus, the entire combustion is completed in the coke burning chamber and the body of the cupola furnace. Thereby, the utility model raise the heat efficiency of the entire process for melting iron.
