一种蒸汽湿度测量装置及其性能分析
摘要
提出了一种采用热力法测量汽轮机排汽湿度的简易装置
详细分析了其测量原理与测量精度。该装置不受汽流中水滴直径的限制
不需要对湿度进行标定
简易便携且其测量相对误差在2%左右
能够满足实际需求。
Abstract
A kind of simple and convenient exhaust steam moisture measuring meter adopting thermal method has been put forward
it is unlimited by the diameter of water drops in steam flow
and the steam moisture isn't necessary to be calibrated
being simple and easy to carry.The working principle and precision in measurement have been analysed in detail
it shows that the relative error in measurement is about 2%
satisfying the requirements in practical application.
