| Abstract: | There exists serious steam leakage in the gland steam system for turbo generator 200MW unit of Zhengzhou Xinli Power Generation Co. Ltd. This leakage results in the lubrication oil with water, and high hydrogen humidity. Furthermore, those factors, such as the complicated system, a plenty of manual adjustment, and complex regulation during handling accidents, can cause potential problems for the unit safety operation. This paper analyzes the problems existing in the gland steam system, and puts forward the improving solution for the overhaul of the units. After the system reconstruction, the corresponding control and regulation mode of the system will be changed. The leakage problem, therefore, will be solved successfully, and a good foundation will be laid for the safe operation of the unit. The successful experience of reconstruction will offer the reference for the counterpart units. |
