Abstract
In this article, a novel combustor for stable, high efficiency, and low pollution combustion of mixture of purge gas and crude gas is proposed; experiments and numerical simulation were undertaken. Hot wire anemometer was employed to investigate the velocity profiles and some detailed flowing characteristics were studied by using a numerical simulation method. The results of the experiments and simulation agreed well, and an obvious recirculation region was found downstream from the secondary air distributors. The recirculation rate could be adjusted conveniently. Configuration parameters of secondary air distributors were optimized and better flow fields were achieved.
