摘　　要：循环流化床锅炉出口结构对炉内气固两相流动特性有很大影响，称为循环流化床锅炉出口端头效应。本文通过试验分析了循环流化床锅炉出口端头效应的机理，并提出了强化出口端头效应的方法。Exit geometric configurations greatly influence the hydrodynamic characteristics in circulating fluidized bed boilers. This phenomenon is called the exit end effect of a circulating fluidized bed boiler. This paper is devoted to analyzing the mechanism of the exit end effect and providing a method to enhance the exit end effect.

关 键 词：循环流化床锅炉 出口端头效应 内循环 两相流
