low excess air

基本解釋

According to the results, the air excess factor in boiler furnace causes low heat efficiency.
其結(jié)果表明：爐膛內(nèi)空氣過剩系數(shù)偏小導致鍋爐熱效率偏低；
The optimum operation of pulse combustor means successful ignition and stable combustion with high intensity, low excess air and low CO emission.
脈沖燃燒器的最佳運行工況應能順利點火并在低過剩空氣系數(shù)下高強度穩(wěn)定燃燒。
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.
冷凝式鍋爐的熱效率提高潛力主要取決于燃料種類、鍋爐本體的排煙溫度、工藝流體的溫度、所需的低品位熱能的數(shù)量、過量空氣系數(shù)等。
