一、转子的热应力汽轮机在启动、停机和负荷变化时,部件金属内部将产生较大的温度梯度和由此而产生的热应力。这种过渡工况下的热应力是影响机组调峰适应负荷变化和机组寿命损耗的重要因素。
First, the thermal stress of the rotor Steam turbine at startup, shutdown and load changes, the internal parts of the metal will have a greater temperature gradient and the resulting thermal stress. The thermal stress under such transitional conditions is an important factor that affects the unit’s peak load to adapt to load changes and the unit’s life loss.
