摘要

针对300 MW机组的循环流化床(CFB)锅炉冷态起动、汽轮机中速暖机过程中遇到的如主再热汽温无法提升

主汽压力异常升高

过热度下降

汽轮机暖机效果无法保证等问题

分别从锅炉起动初期运行调整和汽轮机运行控制两方面进行分析

并提出了相应的解决方法。实施后

取得了良好的汽轮机暖机效果。

Abstract

Directing against problems encountered in the process of cold-state start-up of boiler and medium speed warm-up of the steam turbine for the first 300 MW CFB unit manufactured in China

such as the temperature of main reheated steam is unable to be risen

the main steam pressure being abnormally enhanced

superheat degree being lowered

and the effectiveness of steam turbine warm-up being unable to be ensured etc.

analysis has been carried out from two aspects

i.e.operation adjustment in initial period of boiler start-up

and operation control of the steam turbine

respectively

and corresponding solving methods being put forward.After implementation

good effectiveness of warm-up for steam turbine has been obtained.
