循环流化床锅炉回流阀研究

Research on Nonmechanical Valves of Circulating Fluidized Bed Boiler

在对循环流化床锅炉关键部件之一的回流阀的试验研究基础上，论述了回流阀的工作原理和设计计算方法。对影响回流阀正常运行的主要因素如立管中密床高度、鼓风点离阀水平段中心的位置以及阀的水平段最小安全长度等进行了试验和测定，可作为流化床锅炉设计和运行的参考。

Based on the research of nonmechanical valve that is major componets of a circulating fluidized bed boiler, the author expatiates on design methods and operating orinciple of L-valves,makes scientific researches on the operating parameters of L-valves.
