Dynamic Analysis on Commutation of Regenerative High Temperature Air Combustion With Reverse Direction

LIU Zhao-miao, YU Hai-yuan, JIN Yan-mei, YE Hong-ling (College of Mechanical Engineering and Applied Electronics Technology, Beijing University of Technology, Beijing 100022, China)  
The authors simulated the dynamic properties of the regenerative high temperature air combustion system with reverse direction. It can be found from the results that, with the increasing of time, the flame's highest temperature in the furnace decreases, the average temperature increases, and the temperature in furnace became more even. With the decreasing of oxygen concentration, the concentration of NOx reduces. With the increasing of preheat air temperature, the highest and average temperatures, and the amount of nitrogen oxide also increase, inversely, the influence become smaller. It is also seen from the contrast analysis on temperature field for the concentration of nitrogen oxide and carbon dioxide at the fuel velocity of 0.25 m/s and 0.5 m/s that the dynamic properties of low oxygen combustion system at the fuel velocity of 0.25 m/s are preferred.
