唐湖电厂1^#炉主汽温偏差大原因分析及处理

Reason Analysis and Treatment of 1^# Boiler Main Gas Temperature Large Deviation in Tanghu Thermal Power Plant

唐湖电厂2台135 MW机组是世界上海拔最高,单机容量最大的机组。文章介绍了唐湖电厂1#炉在调试期间发现主汽温偏差大问题,并进行原因查找、分析及处理全过程。它的顺利投产,为高海拔燃煤机组提供了大量的试验数据。

The 2 × 135 MW unit of Tanghu Themal Power Plant is the largest capaicity and highest elevation in the world. The paper in troduces the main gas temperature large deviation problem in the 1^# boiler of Tanghu Themal Power Plant, and makes investigation, anaylsys and treatment for the reason. After putting into operation, it provicdes nu- merous testing data for the high elevation and coal combustion units.
