空气预热温度 meaning in English

air-preheating temperature

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
首先建立了完善灵活的低no _ x燃烧实验系统，在实验系统上完成了燃烧温度、过量空气系数、预先加入一定量的水蒸汽、空气预热温度、对燃气预先进行微波处理、烟气再循环燃烧以及燃烧方式(扩散式与预混式)对no _ x生成的影响分析；采用phoenics3 . 5软件进行了液化石油气燃烧的数值模拟。
