Experimental Modelling Research on Gas Velocity Distribution in Flue Ducts of Corner Tangentially Fired Boilers

Che De-fy; Hui Shi-en;Xu Tong-mo;Guo Hongsheng; Chen Tie; Wei Xiao-ling; Zhang Xuan(Xi'an Jiaotong University)  
Abstract The gas velocity distribution in the regions of superheaters and reheaters of large power boilers is obtained with a hot-wire anemometer in a modelling test rig. According to test and analysis results, non-uniformity factors of the gas velocity distribution are given. Effects of steam load, operating nozzle combination and ratio of flow momentum on velocity distribution are discussed.
