锅炉

In this thesis, a design-oriented model of the solid recycle system in CFB boiler is proposed to calculate main design parameters of the standpipe.

最后，本文提出了适用于循环流化床锅炉固体颗粒再循环系统中返料立管的设计模型和主要参数的确定。

ABSTRACT Circulating Fluidized Bed is widely used in fossil fuel combustion because of its high efficiency and low pollution. In CFB boiler , the burning and slagging in the standpipe affect seriously the operation of boiler.

循环流化床燃烧技术因其高效清洁的特点得到了大力发展，但循环流化床锅炉立管内物料燃烧结渣是目前急需解决的问题之一。

A critical review of experimental and theoretical results of standpipe and non-mechanical valves are given in detail. The measurement method on solids circulating flowrate as well as the flow property of gas-solid mixture through orifice are surveyed.

本文对迄今为止国内外对返料立管和非机械阀的研究现状和研究结果进行了详细的综述，归纳总结了实验与锅炉实际运行过程中固体颗粒循环量的测量方法以及气固混合物通过孔口的流动特性。

The model takes account of CFB boiler components such as the dense and dilute region, gassolid separator, standpipe and recycle device in detail. Several main parameters and features of CFB boiler are calculated.

同时以小室概念为基础，结合相应的数值计算方法对锅炉不同运行工况下的循环回路一些主要参数的动态过程进行了大量的模拟计算。
