火电厂高压给水加热器运行故障的分析和改造

Analysis and transformation on high pressure feedwater heater and drain pipe leakage in thermal power plant

高压给水加热器及疏水管道泄漏是火电厂常见的问题,会危及汽轮机的安全运行,导致锅炉给水温度降低,经济性下降。通过分析火电厂高压给水加热器疏水管道、弯头、钢管及水汽法兰泄漏的原因,提出检修、改造和防范措施,以保障机组运行的安全性和火电厂整体的经济性。

It is a common problem that the leakage of high pressure feedwater heater and drain pipe leaks in thermal power plant, which would endanger the safe operation of the turbine, resulting in the temperature decrease of boiler feed water and the economy decline. The leakage reason for high-pressure feedwater heaters drain pipe, angle head, pipe and flange for water and vapour steam was analyzed. measures were thermal power put forward to plant. The examination and repairment, transformation and defending achieve the safety of generator operation and economic benefits of
