Numerical Simulation Research of New Type Gas Burner
The numerical simulation method was used to investigate the combustion characteristics of a new type gas burner with adjustable self-sucked flue gas recirculation(FGR),and the influences of the size of premix chamber and ejector throat on combustion characteristics were analyzed.The results show that the premix chamber size had an important influence on flue gas recirculation(FGR).While the premix chamber too big or too small,it was unfavorable for FGR.Larger throat diameter of ejector contributed to more amount of recirculation flue gas.And with increasing the amount of recirculation flue gas,the peak flame temperature position moved forward and the flame length got shortened.
