Abstract :
High temperature air combustion provides the significant advantages of high thermal efficiency, reduced pollution, and low fuel consumption. The mathematical model for HTAC is built and the effect of oxygen concentration of entrancing chamber on combustion and NOx emission is investigated by using numerical simulation. In this paper, keeping the inleting oxygen concentration unchanged or unchanged have been made a comparative study. The results show that with the decrease of the entrancing chamber of oxygen concentration can effectively reduce the furnace temperature and make the furnace temperature more even uniform, and reduce the NO concentration.
