A NEW METHOD FOR REDUCING THE FLOW VELOCITY DEVIATION OF TANGENTIALLY FIRED UTITITY BOILER HORIZONTAL GAS PASS

Li Yongguang Zhu zhenjin Liu Song Guo Xigeng Zhang Delong Department of power Engineering, Shanghai Institute of Electric Power, Shanghai, 200090 China  
In this paper, a new method, biasing SH panels, was developed to improve the situation of flow velocity deviation of tangentially fired boiler horizontal gas pass. Under the condition of experiment in the paper, the best way is to compose biasing SH panels, and it makes the velocity deviation coefficient reduce 85%. On the every condition of biasing SH panels at different angles 30°,45°,60°,the velocity deviation coefficient on horizontal gas pass reduces about 30% separately. Test expressed that the method developed in this paper is effective, and it provided a new means to raise the safe and economy level and prevent the accident of overheating bursting pipe taking place.
