主 题：Biogas Combustion instabilities Pollutant emissions Gas turbine combustor Dilution
摘 要：In this study,combustion instabilities and flue gas emission changes under different dilutions of N_(2)(nitrogen)and Ar(argon)of a promising biogas mixture(70%CH4-30%CO_(2))in the fight against greenhouse gas emissions were *** the experiments,additions were made from 0%to 50%at intervals of 10%for both *** order to detect the instability of the flame,external acoustic enforcements at different frequencies was applied through the speakers placed in the combustion chamber *** dynamic pressure fluctuation values were *** results showed that low dilution ratios were effective in reducing flame instability for both inert ***,as the dilution ratio increased,the fuel/air mixture became leaner and blowoff *** the case of comparing two different gases,it has been observed that the effect of argon gas on reducing dynamic pressure fluctuation is *** outlet temperature and brightness values of the flame decreased in both Ar and N_(2)*** and NOx emissions increased with increasing diluent volume for all dilution *** the emissions of the two diluent gases are compared,the CO emission,which was 3134 ppm in the undiluted condition,increased up to 4949 ppm in 50%Ar dilution,while it increased to 4521 ppm in 50%N_(2)dilution.
