汽轮机通流状态经济性评估技术的现场应用

对影响汽轮机通流效率的各项因素的作用机理进行了定性分析,并对汽轮机通流状态经济性评估的基本概念进行了阐述。进行汽轮机通流部分经济性状态评估后,可以利用相关的分析工具软件对影响汽轮机通流部分经济性的因素进行有效分析及计算,为电厂大修中汽轮机的检修提供检修的重点。以某一超临界660MW汽轮机为例,给出了汽轮机通流状态经济性评估的大修通流状态实测数据及评估结果,在此基础上确定了汽轮机大修的重点检修工作。

The Application of Steam Turbine Steam Path Audit Technology

Analysis was made on the factors influencing the turbine steam path efficiency,and the concept of the turbine steam path audit was introduced.Using the turbine steam path technology,quantitative analysis and calculation for the factors influencing the steam turbine efficiency can be made using relevant tool software,which can help the decision making of the key maintenance area during the turbine overhaul.An example was given for one super-critical steam turbine,including the measurement data got during the turbine overhaul and the audit results,and the key maintenance tasks set out based on the steam path audit.
