Here an example is: heating the feedwater of condensing turbine by exhaust steam of a back pressure turbine (through tubular steam cooler) to raise the set's heat economy.
介绍一例：利用管式蒸汽冷却器将背压机排汽加热凝汽机给水，从而提高机组热经济性。
The pressure limit valve is still used to cover the steam nozzle for ensuring the surplus steam to exhaust freely.
汽嘴之上仍用压阀扣上，以保证多余的蒸汽能自由排放。
With regard to the impact on machine unit economic performance of exhaust steam pressure variation a new quantitative method, I.
针对排汽压力变化对机组经济性的影响，提出一种新的定量方法——排汽压力等效热降计算法。
Higher gas inlet temperature, lower steam pressure or pinch point temperature difference lead to lower exhaust gas temperature, larger evaporation and higher efficiency;
提高进口烟气温度、降低蒸汽压力或减小节点温差，均可显著降低设计出口烟气温度，从而增大蒸发量，提高热效率；
Moreover, the self maintaining switch is relatively far from the pressure limiting exhaust valve, thereby avoiding the operator from being scalded by the steam.
而且自持开关离开限压排气阀较远，操作者能避免蒸汽烫伤的危险。
Following the gradual enlargement of steam generation pressure, the flow velocity of exhausting steam is accelerated; then, the valve core is pushed upwards to block an air exhaust passage.
随着产生蒸汽的压力逐渐增大，排出蒸汽的流速加快，将阀芯上推堵住排气通道。
