摘要

研究汽轮机中流动湿蒸汽湿度和水滴直径的测量

指出了光学探针法和热力学法的局限性。采用激光散射法原理设计的测量装置测量蒸汽湿度和水滴直径

并且给出了一次水滴和二次水滴的具体测量方法。该方法为实时监测汽轮机流动蒸汽的湿度和水滴直径提供了必要条件。

Abstract

The study on measuring steam humidity and diameter of water droplet flowing through the steam turbine has been presented

pointing out the limitations in application of two existed methods based on optical probe and thermodynamics respectively.A measuring facility has been designed by using the principle of laser scattering method

and the concrete measuring method for primary and secondary water droplet being given.The said method provides with necessary conditions for real-time monitoring steam humidity and diameter of water droplet in steam flowing through the steam turbine.
