燃气分析测量高温燃气温度的方法

Methods for Gas Temperature Measurement by Gas Analysis

叙述了两种根据燃气成分推算高温燃气温度的计算方法——效率/余气系数法和焓值守恒法。效率/余气系数法根据燃气分析得到的余气系数和燃烧效率计算燃气温度,按燃烧效率和余气系数计算方法的不同又划分为补燃法和全成分法;焓值守恒法根据燃气成分和焓值计算燃气温度。分析和比较了两种计算方法,这些方法已应用到燃烧室出口高温燃气温度测量中。

Two computational methods, Efficiency/Air Excess Coefficient Method (EAEC) and Enthalpy Conservation Method (ECE), for gas temperature measurement based on gas components analysis were presented. The EAEC method uses air excess coefficient and combustion efficiency for gas temperature calculation. EAEC method can further be divided into reheat method and full components method. For the ECE method, the gas temperature is calculated based on gas components and their enthalpy. These methods have already been used for the gas temperature measurement at the exit of the high temperature rise combustor.
