| Abstract: | The cause leading to repeated occurrence of platetumover concerning reduction gearbox of the air preheater surpassing the clutch coupling for boilers No.1~No.4 in Mawan Power Plant has been analysed, and remedial measures, such as modifying startprogramme of the air preheater, and changing the startup mode, being put forward. After implementation of the said measures, the operation of said air preheaters become fully normal, the accident of reduction gear striking the plate to turnover never occurred again, at the same time, providing precedent example and experience for technical retrofit of similar type air preheaters in power plants. |
