excess combustion air

基本解释

These steps prevent formation of any new (thermal) NOx and completes the combustion with excess air.
以上几个步骤迫使不能在该过程中形成氮氧化物，并借助多余空气完成燃烧。
A new concept of achieving high temperature air by circulating fluidized bed combustion at high excess air ratio was proposed.
提出了借助循环流化床在高过剩空气系数下燃烧的技术提供高温空气的新构思。
Influencing factors on heat efficiency of tubular heaters are analyzed, which mainly include excess air factor, imperfect combustion and exhaust temperature.
分析了影响管式加热炉热效率的因素，主要包括过剩空气系数、不完全燃烧、排烟温度等。
