摘　　要：针对某燃煤电厂660MW机组,借助CFD软件对喷射活性炭后烟道内的气固流场进行数值模拟,探究了单喷嘴不同布置方案对活性炭颗粒的覆盖率、停留时间以及颗粒分布均匀性的影响。结果表明,采用布置情景8时,ACI效果最佳,颗粒覆盖率达到了51.53%,停留时间超过7s,且颗粒分布均匀性较高。Taking a 660 MW unit boiler as the research object,the CFD software is used to simulate the gas-solid flow field after injecting activated carbon into the duct.The effects of different single injector layout schemes on activated carbon particulates coverage ratio,residence time and the uniformity of particle distribution were investigated.The results indicate that the activated carbon particulates coverage ratio in the duct reaches 51.53%,and the residence time is longer than 7 s,when the scene 8 is adopted.Moreover,the uniformity of the particle distribution is better.
