Abstract:

This paper introduces the process of heating with coke oven gas and purge gas.The influence of purge gas is analyzed,and the result shows that mixed with purge gas,vertical heating of coke oven is improved,temperature fluctuation in the coking chamber is reduced,labor intensity is reduced,pressure of main pipe in the cellar is increased,the longitudinal temperature meets the specified temperature,and there is no affect to the suction force of flue,formation of graphite or pushing.Therefore,this process brings remarkable economic benefit.
