电厂湿蒸汽管道疏水型式的探讨

Researching Drain Device of Wet-steam Piping in Power Plant

发电厂的湿蒸汽管道均设置连续疏水装置,疏水型式选择的优劣直接影响机组的安全性和热经济性,针对发电厂湿蒸汽参数的特点,提出连续疏水采用带有调节阀的疏水型式,通过与常规疏水型式的经济性分析比较,推荐湿蒸汽管道连续疏水采用带有调节阀的疏水型式。

In the power plants, drain device is set in all the wet-steam piping. The optimum design of drain device is advantage for security and economical of the unit. For wet-steam parameter, Drain device with control valve is presented for continuous drain. According to economic analysis with general drain device, Drain device with control valve is recommended.
