摘要：For the cogeneration steam turbine, due to the thermoelectric load changes frequently, which will cause the back pressure instability, and cause sharp fluctuations in temperature and pressure inside the turbine, these fluctuations will affect the normal work of the turbine rotor, even some mechanical fault. In order to find out the cogeneration steam turbine running at full load, the influence of the thermoelectric load changes to the turbine rotor, analyzed under different thermoelectric load conditions, the trend of the back pressure, and analysis of the temperature and pressure's change in the steam turbine brought about by the back pressure's change as well as the impact of these changes in temperature and pressure brought to the turbine rotor. The conclusion that due to the thermoelectric load's change will cause the turbine rotor thermal bending and axial thrust imbalance.
