摘要:

针对汽轮机启动时机器损耗和燃料损耗都很大且容易出事故这一问题,研究了转子的热应力计算,导出了转子热应力计算公式;根据连续损伤理论,讨论了转子的疲劳损伤计算,并从总损耗最小出发,探讨了汽轮机的优化启动问题.研究结果表明,汽轮机启动时的热应力并非越低越好,而是存在一最佳值,在此值附近启动效益最好.

Abstract:

Aiming at the problem that the machine loss and fuel loss are large and prone to accidents when the steam turbine is started, the calculation of the thermal stress of the rotor is studied, and the calculation formula of the rotor thermal stress is derived. According to the continuous damage theory, the fatigue damage calculation of the rotor is discussed, and the optimization and starting problem of the steam turbine is discussed from the minimum total loss. The results show that the thermal stress at the start-up of the turbine is not as low as possible, but there is an optimal value, and the starting benefit is best around this value.
