摘　　要：截至2024年,大唐滨州发电有限公司2号机组已连续运行7年,机组运行指标热耗值大,高、中压缸缸效降低,且汽轮机内部原镶嵌式阻汽片冲刷磨损较为严重,已影响机组运行经济性。结合2024年2号机组A修机会,进行揭缸完成缸内通流部分镶嵌式阻汽片优化改造,获得比较满意的效果。Unit 2 of Datang Binzhou Power Generation Co.,Ltd.has been in continuous operation for 7 years up to 2024.The unit's operating indicators have a high heat consumption value,a reduced cylinder efficiency of high and intermediate pressure cylinders,and the original inlaid steam traps inside the steam turbine have been seriously eroded and worn,which has affected the operating economy of the unit.Taking into account the opportunity of A-repair of Unit 2 in 2024,the cylinder was removed to complete the optimization and transformation of the inlaid steam traps in the flow passage part of the cylinder,and satisfactory results were achieved.
