据《Теп лоэнергетика》2009年4月号报道,在汽轮机排汽管内,由工质复杂的流动特性引起的能量损失导致末级后压力升高、配置焓降减小、动力装置经济性降低(即循环热效率减小)。此外,排气管显著影响末级的工作条件,该条件明显影响末级工作的效率和可靠性。因此,排 According to the “Теп лоэнергетика” report of April 2009, the energy loss caused by the complex flow characteristics of the working fluid in the steam turbine exhaust pipe results in an increase in the post-stage pressure, a reduction in enthalpy drop and a reduction in the power plant economy Cycle thermal efficiency is reduced). In addition, the exhaust pipe significantly affects the final working conditions, which significantly affect the efficiency and reliability of the final work. Therefore, row
