摘　　要：讨论了汽轮机低压排汽缸排汽压力的高、低变化和真空恶化后的工况对汽轮机通流部分的影响,为北方地区的汽轮机低真空供热提供了参考,以便当汽轮机处于异常工况时确定其最合理的运行方式。The influences of LP exhaust pressure variation and vacuum deterioration on the flow path of steam turbine are discussed. It offers references for the cogeneration operation at low vacuum of steam turbine in northern area so that the most rational operation mode can be defined when the steam turbine operates on abnormal conditions.

关 键 词：低压排汽缸 排汽压力 低真空供热
