Estimation of NOx Emission From Light Gas Turbine Combustor

In order to solve the problem of NOx emission estimation,the NOx emission law of light gas turbine combustor was studied by numerical simulation method.The numerical analysis results were compared and analyzed with the empirical formula calculation data in the literature,and the accuracy of the numerical method was verified.The NOx emission estimation formula was fitted based on inlet pressure,air mass flow rate and main combustion zone temperature.The results show that the NOx emission values obtained by numerical simulation are in good agreement with those calculated by empirical formulas in the literature.The NOx emission estimation formula is obtained based on numerical calculation results.The formula can effectively reflect the effect of the above three parameters on NOx emission.The results of the NOx estimation model established by the verified high precision numerical simulation method are scientific and reliable,and the test cost can be reduced.
