    • A steam cycle power plant (10) is provided that may include a steam source generating steam (40), a steam turbine (24) receiving the generated steam and discharging an exhaust steam, a condenser (44) receiving the exhaust steam and an atomizer (60) for injecting water into the exhaust steam downstream of the steam turbine (24) and upstream of a cooling surface of the condenser (44) effective to reduce a backpressure on the steam turbine (24) and improve a heat rate of the steam turbine (24). The atomizer (60) may include a plurality of symmetrical spaced fluid connections (70) and a plurality of atomizing nozzles (62) affixed proximate at least one exhaust end of the steam turbine (24). The power plant (10) may be a combined cycle power plant including a heat recovery steam generator (40) and a gas turbine engine (12).
    • 提供一种蒸汽循环发电厂(10),其可以包括产生蒸汽的蒸汽源(40),接收所产生的蒸汽并排出排气的蒸汽轮机(24),接收排气的冷凝器(44)和雾化器 (60),用于将水注入蒸汽涡轮机(24)下游的排气蒸汽和冷凝器(44)的冷却表面的上游,以有效地减少蒸汽轮机(24)上的背压,并提高蒸汽的热速率 涡轮机(24)。 喷雾器(60)可以包括多个对称间隔开的流体连接件(70)和靠近蒸汽轮机(24)的至少一个排气端附近的多个雾化喷嘴(62)。 发电厂(10)可以是包括热回收蒸汽发生器(40)和燃气涡轮发动机(12)的联合循环发电厂。
