对改用循环水供热汽轮机的安全性分析

Safety analysis of turbine supplied heat with circulation water

汽轮机组的热电联产改造可提高其热效率和经济性,但改造后机组的运行工况也随之发生了变化．通过对一台双抽汽供热汽轮机组改造后实际运行的检测,从热膨胀、受力情况和运行稳定性方面进行了分析论证,并指出了存在的问题和改造过程中的注意事项．

Innovation of heating and power cogeneration can improve thermal efficiency and economy performance of turbine,after innovation, operation situation of turbine changes. Measures the operation situation of innovated turbine, analyses the thermal expansion, stress and stability, points out the problems and notice on the course of innovation.
