摘要：

通过多孔介质燃烧器的燃烧试验研究低氮燃烧器的稳燃范围，探究在不同功率（50~100 kW）和当量比（0.6~1.0）下燃烧器的氮氧化物（NOx）和一氧化碳（CO）的生成特性，探讨多孔介质直径对燃烧器燃烧产物的影响.结果表明，燃烧器稳燃上限和稳燃下限均随当量比的增大而增大，并且稳燃上限的增幅大于稳燃下限；天然气在多孔介质内燃烧时生成的氮氧化物主要为NO，其排放质量浓度随燃烧器功率和燃烧当量比的增大而增大.在试验工况范围内，氮氧化物排放质量浓度低于30 mg/m3，工业级多孔介质燃烧器具有低氮排放特性；CO排放质量浓度随当量比的增大先降低后升高，在当量比小于0.9时，CO排放质量浓度低于56 mg/m3；为了同时实现较低的NOx和CO排放，燃烧器运行的当量比范围应控制在0.7~0.8.研究的2种多孔介质直径对燃烧器的NOx和CO排放质量浓度没有明显影响.
Abstract:

A combustion test of porous media burner was conducted to investigate the stability limits of low nitrogen burner. Characteristics of nitrogen oxide (NOx) and carbon monoxide (CO) emissions of the burner at varied burner powers from 50 kWto 100 kW and varied equivalence ratios from 0.6 to 1.0 were presented. The influence of porous media diameter on the combustion production was also studied. Results showed that the stable operating range extended and shifted to larger values while the equivalence ratio increased, and the upper limit increased greater than the inferior limit. NO was the main component of oxynitride when natural gas combusted in the porous media burner. The NOx emission increased with the burner power and the equivalence ration. The maximum NOx emission of the burner was below 30 mg/m3 for all operating conditions. The industrial porous burner has low NOx emission characteristics. CO concentration increased after a decrease with the rise of equivalence ratio, and it was below 56 mg/m3 when the equivalence ratio was smaller than 0.9. To achieve low NOx and CO emissions at the same time, the equivalence ratio should be controlled between 0.7 and 0.8. There is no significant changes in NOx and CO emissions for the two porous media diameters.
