摘　　要：由于燃煤细度以及运行参数选择的不合理,部分循环流化床锅炉冷渣器经常发生渣自流,严重影响了机组的安全稳定运行。通过对影响渣自流的相关因素进行模拟试验,提出了相应的治理措施,在多台锅炉进行相应的技术改造后取得了显著效果。Due to inappropriate coal fineness and unreasonable operational parameters,bottom ash artesian flow is frequently encountered in the cooler of circulating fluidized bed（CFB）boilers,which seriously affects the safety and steady operation of the unit.By conducting simulation tests on relevant factors that contribute to the bottom ash artesian flow,corresponding countermeasures are proposed and taken,after which significant effects are obtained for several boilers.

关 键 词：循环流化床锅炉 渣自流 应对措施
