Abstract:The No.1 300MW boiler in Zhanjiang Power Plant has had the problems of local overheating of high temperature reheater and large steam temperature deviation at the exit of reheaters for a long time.According to the cold test of flow field at the high temperature reheaters' entrance and exit and the hot test of temperature field at it's entrance,the cause of reheater's overheating and steam temperature deviation is analyzed and an explanation associating with the structure of reheater's tubes is made.
Keywords:reheater   overheating   boiler   flue-gas temperature deviation
