大型循环流化床锅炉支承结构与膨胀系统的探讨

在综述国内外大型循环流化床锅炉支承结构及膨胀系统的基础上,对循环流化床锅炉膨胀系统的设置和膨胀节的安装使用方式进行了探讨。重点阐述了几种典型循环流化床锅炉的支承结构和膨胀节设置的一般规律,并介绍了一种能将多维膨胀简化为一维膨胀的膨胀节设计新思路。

Consideration on Supporting Structure and Expansion System in Large-Scale CFB Boilers

On the basis of summarizing supporting structure and expansion system of domestic and external large-scale CFB boiler, the setup of expansion system and the scheme of application of expansion joints are discussed. The general orderliness of supporting structure and expansion system in some typical large-scale CFB boilers is particularly expounded, and a new idea of expansion joints design to simplify multidimensional expansion into one-dimensional expansion is introduced.
