low excess air 中文意思是什麼
low excess air
解釋
低過量空氣-
In this paper a perfect and flexible experimental system of low nox combustion is established firstly. the influences of the temperature of combustion, the air excess coefficient, a certain amount of vapor added in advance, the temperature of preheated air, adding microwave into gas before combustion, gas recycling combustion and the mode of combustion ( diffused and premixed ) on nox emission are analyzed respectively. the combustion of liquid petroleum gas is simulated with phoenics 3. 5
首先建立了完善靈活的低no _ x燃燒實驗系統，在實驗系統上完成了燃燒溫度、過量空氣系數、預先加入一定量的水蒸汽、空氣預熱溫度、對燃氣預先進行微波處理、煙氣再循環燃燒以及燃燒方式（擴散式與預混式）對no _ x生成的影響分析；採用phoenics3 . 5軟體進行了液化石油氣燃燒的數值模擬。 -
This paper also analyzes the ash wear mechanism, and then does the effects of low temperature economizer wear five factors : the first is the smoke corridor caused by wear mechanism, the second is the impact on the wall material, and the third is that of flying ash concentration, the fourth of the excess air ratio, and the fifth is the change in the composition of the gas to wear the impact
分析了飛灰磨損的機理，然後分析了影響低溫省煤器磨損的5種因素，一是煙氣走廊引起磨損的機理；二是管壁材料的影響；三是飛灰濃度的影響；四是過量空氣系數的影響；五是煙氣成分的變化對磨損的影響。 -
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
並且通過試驗的方法，著重探討了通過調整過量空氣系數來使鍋爐燃燒達到優化的低氧燃燒技術。 -
It is firstly found that the nox concentration increases rapidly when is less than 0. 75, which complements the staged combustion and the rich - lean combustion that are well considered currently as low nox combustion. it does not mean that the combustion must be the low nox combustion when < 1. there is a limited least value of air excess coefficient
對目前普遍認為的分級燃燒和濃淡燃燒可以降低no _ x排放的提法給予補充，即對一次過量空氣系數有一個最小值限定，不是小於1的任何值都可以，低於最小限定值將是不利的，而且一次過量空氣系數有一個最佳值。
