汽轮机回热加热器端差异常分析及解决措施

Analysis and Solving Measures of the End Difference of Steam Turbine Heat Recovery Heater

汽轮机回热系统的正常运行是汽轮机组正常运行的保障,采取有效措施解决回热系统故障对保证汽轮机组的安全性能有着重要的意义。调查了300 MW汽轮机回热加热系统的运行现状,通过分析加热器端出现差异常问题的原因,给出了有针对性的解决措施。

The steam turbine to the normal operation of the heat recovery system is the guarantee of the normal operation of steam turbine unit, to take effective measures to solve the heat recovery system fault to ensure the safety performance of the steam turbine unit has an important significance. In this paper, the operating status of the heat recovery system of the 300 MW steam turbine is investigated, and the reasons for the difference of the heater are analyzed, and the solutions are given.
