循环流化床(CFB)锅炉膨胀节的布置及结构分析

The Arrangement and Structure of Expansion Joints in CFB Boiler

针对多种型式、结构和等级的循环流化床(CFB)锅炉产品,旋风分离器进口烟道、回料腿非金属膨胀节在锅炉投运运行后经常发生拉裂、漏灰现象,同时其安装,检修空间非常小,对旋风分离器进口烟道、回料腿非金属膨胀节容易拉裂、漏灰的原因进行了分析,同时也对布置空间进行分析研究,提出了相应的解决措施。

As for the CFB products with various types, structure, and capacity. The non- metal expansion joints which located at the cyclone inlet flue and the seal leg occurred some problems, such as the coat ripping and ash leaking. At the same time, the space was too narrow to assembly and repairing the expansion. This topic talked about the reason for these failures, studied the arrangement space and put forward several considerable measures to solve the problem.
