30万瓩汽轮机回热系统中的混合式加热器的设计与运行经验表明,与广泛应用的无压配水方式相比,有压配水方式具有一系列优点。达到同一效果——将水加热到蒸汽的饱和温度,加热部分的容积可以缩小.它还可以布置在蒸汽管道范围内。此外,由于蒸汽与水同向运动,在加热器中不可能产生极限工况(水动力稳定性被严重破坏的工况—译者注),在多级 The design and operation experience of the hybrid heater in the 300,000-瓩 steam turbine heat recovery system shows that compared with the widely used non-pressured water distribution system, the pressured water distribution system has a series of advantages. To achieve the same effect - the water heated to the steam saturation temperature, the heating part of the volume can be reduced.It can also be arranged in the steam pipe range. In addition, due to the steam and water moving in the same direction, it is impossible to produce the limit condition in the heater (the condition of hydrodynamic stability is severely damaged)
