low excess air

The optimum operation of pulse combustor means successful ignition and stable combustion with high intensity, low excess air and low co emission.

脉冲燃烧器的最佳运行工况应能顺利点火并在低过剩空气系数下高强度稳定燃烧。

The potential for efficiency improvement depends mainly on the fuel type fired, the exit flue-gas temperature, the process fluid temperature, the low-level heat required, and the excess air etc.

冷凝式锅炉的热效率提高潜力主要取决于燃料种类、锅炉本体的排烟温度、工艺流体的温度、所需的低品位热能的数量、过量空气系数等。

And by means of testing, the thesis puts emphasis upon the study of the low-oxygen combustion technique, which can optimize boiler's combustion by adjust the excess air factor.

并且通过试验的方法，着重探讨了通过调整过量空气系数来使锅炉燃烧达到优化的低氧燃烧技术。
