在此狭长受限空间结构的燃烧炉中，单独改变α对焦炉煤气的燃尽率影响不明显，焦炉煤气燃烧比较充分。在T₀=923 K且燃烧负荷为84％时，α从1.0增大至1.2时，可使炉膛平均温度维持在1580 K，NOx降低了44.4％，NOx排放浓度降低至250 ppm。

In the combustion furnace with narrow and confined space structure, the effect of changing α alone on the burnout rate of coke oven gas is not obvious, and the combustion of coke oven gas is quite sufficient. When T0=923 K and combustion load is 84% and α increases from 1.0 to 1.2, the average temperature of the furnace can be maintained at 1580 K, NOx is reduced by 44.4% and NOx emission concentration is reduced to 250 PPM.
