摘要
在大型湿冷火电机组中,凝汽器的压力变化越来越受到关注,降低凝汽器的压力,就可降低汽轮机的热耗。大型电站的汽轮机低压缸与凝汽器的喉部相连,结构较为复杂。凝汽器管束的布管方式,对凝汽器内流场的分布有很大的影响。研究蒸汽在低压缸和凝汽器壳侧的流动和阻力,对于提高汽轮机整机的运行效率有很大价值。
In large wet cooling thermal power units, the change of condenser pressure is getting more and more attention. Reducing condenser pressure can reduce the heat consumption of steam turbines. The steam turbine low pressure cylinder of a large power station is connected with the throat of the condenser, and the structure is rather complicated. The way of tube arrangement of condenser tube bundle has great influence on the distribution of flow field in condenser. It is of great value to study the flow state and resistance of steam on the low pressure cylinder and condenser shell side.
