摘要：
The effect of inlet gas temperature on the flow and temperature fields and the emission of the main pollutants (CO and NOx) in the combustion chamber was analyzed by numerical simulation of a 100 kW micro gas turbine with constant excess air ratio, constant gas turbine power and different inlet gas temperatures. The combustion reaction principle used in the study is a simplified version of the Gri-Mech 3.0 mechanism, which includes 17 components and a total of 24 elementary reactions. The simulation results show that as the inlet gas temperature gradually increases, the maximum temperature in the main combustion zone of the combustion chamber gradually increases, the temperature distribution of the gas exiting the combustion chamber becomes more uniform, and the gas quality gradually improves; the CO emission concentration gradually decreases, but the NOx emission gradually increases. ©2022 Chin.Soc.for Elec.Eng.
