【Abstract】 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.更多还原
