摘要

加热器出水温度是判断加热器运行状况的重要监视参数。以马鞍山电厂11号汽轮机组2号低压加热器(低加)为例

分析了其出水温度异常的原因为4号低加换热器铜管大量泄漏

排挤3号低加抽汽

进而排挤2号低加六段抽汽而致。介绍了消除低压出水温度异常所采取的对策与处理结果。

Abstract

The outlet-water temperature from heaters is an important supervisory parameter for judging the operation situation of heaters.Taking the low-pressure heater no.2 of steam turbine unit no.11 in Ma'anshan Power Plant as an example

the causes leading to abnormal outlet-water temperature have been analysed

it is believed that the large amount of leakage from copper tubes in heat exchanger of the low-pressure heater no.4 pushes aside the extraction steam of low-pressure heater no.3

and then pushes aside the extraction steam in sixth section of the low-pressure heater no.2

thereby the outlet-water temperature from the low-pressure heater being decreased.The adopted measures to eliminate the fault and the obtained results have been presented.
