汽轮机低压缸排汽通道优化改造

摘要

Steam turbine low-pressure cylinder exhaust channel optimization reform, is to install the curve-shaped diversion device on the steam turbine low-pressure cylinder, so that the flow field of the steam turbine low-pressure cylinder into the condenser cooling tube is reasonable, the heat load of the condenser heat exchanger is even, the heat transfer efficiency is increased, the exhaust pressure is lowered to increase the unit vacuum, The purpose of increasing unit economy.%汽轮机低压缸排汽通道优化改造,是在汽轮机低压缸排汽通道上加装曲线形状的导流装置,使汽轮机低压缸排汽进入凝汽器冷却管束的流场趋于合理,凝汽器换热管的热负荷均匀,提高了传热效率,降低排汽压力以提高机组真空,提高机组经济性的目的.
