Abstract:

The burning process of gas in the vertical flue of coke oven belongs to the diffusion combustion, the diffusion combustion is beneficial to the vertical uniform heating of coke oven and to reduce energy consumption. The height of flame produced from diffusion combustion was calculated in the paper, the influence of blast furnace gas heating and coke oven gas heating and the influence of waste gas circulation on flame height were compared. At the same time the factor of influencing flame height was also analyzed and the problem of coke oven vertical heating was solved.
