摘　　要：介绍了电站项目带有内置疏水冷却器的低压加热器,重点讨论了此种类型低压加热器内部流场分析。通过对低压加热器进行三维建模,应用Fluent软件进行数值模拟,对低压加热器内部蒸汽流场的静压分布规律、速度分布规律和温度场分布进行分析。This paper introduces the low pressure heater with built - in drain cooler, and focuses on the internal flow field analysis of this type of low - pressure heater. Through the three-dimensional modeling of the low-pressure heater, the numerical simulation was carried out by Fluent software, and the static pressure distribution, velocity distribution and temperature field distribution of the internal steam flow field of the low-pressure heater were analyzed.

关 键 词：内置疏水冷却器 低压加热器 流场分析
