提高发电机组磨煤机可靠性及降低排矸量的措施探讨--以中国国电集团公司太原第一热电厂为例

摘要

以中国国电集团公司太原第一热电厂五期工程300 MW汽轮发电机组为例，分析了影响机组磨煤机、排矸机等设备可靠性的因素，探讨了降低机组排矸量的主要措施，以期提高机组运行的可靠性和经济性。%Taking 300 MW turbogenerator unit of Taiyuan First Thermal Power Plant’s fifth phase project of China Guodian Corporation as an example, this paper analyzes the factors influencing the reliability of the unit’s coal mill,gangue discharge machine and other equipment, and probes into the main measures for reducing the gangue discharge amount of the unit in order to improve the reliability and economy of unit’s operation.
