通过对液化石油气和焦炉煤气两种不同燃料在狭长受限空间内燃烧过程的分析，结果表明焦炉煤气燃烧时，可以观察到扰动的火焰轮廓，炉内呈刺眼的亮黄色，其燃烧高温区主要集中在前中部位置，即距炉膛底部200 mm~600 mm位置，炉膛温度从下至上，先升高后降低。与液化石油气燃烧相比，焦炉煤气燃烧时炉膛温度分布更加均匀。

Based on two different fuel liquefied petroleum gas and coke oven gas combustion process in the limited narrow space analysis, results showed that the coke oven gas combustion, the flame of a disturbance can be observed, in furnace is dazzling bright yellow, before its burning high temperature mainly concentrated in the central position, namely from 200 mm to 600 mm at the bottom of the chamber of a stove or furnace, furnace temperature from the bottom, It goes up and then it goes down. Compared with LPG combustion, the temperature distribution in coke oven gas combustion furnace is more uniform.
