在此狭长受限空间结构的燃烧炉中，T₀降至723 K时，负荷44％、58％条件下，α和λ对NOx减排效果不明显；而在负荷74％下，将α和λ控制在1.2和20％，可使炉膛平均温度维持在1380 K，NOx排放浓度最低，最低降至41 ppm。

In the combustion furnace with narrow and confined space structure, α and λ have no obvious effect on NOx emission reduction when T₀ drops to 723 K and the load is 44% and 58%. However, under the load of 74%, the average temperature of the furnace can be maintained at 1380 K and the NOx emission concentration can be reduced to 41 PPM when α and λ are controlled at 1.2 and 20%.
