大型锅炉汽包水位测量特性研究与配置优化

Study on the cha racteristic of drum water-level measurement in large-scale boilers and deploy ment optimization suggestion

针对目前火电厂大型锅炉汽包水位测量存在的问题,通过对各种测量方式的特性研究,提出了差压式水位计较为精确的工程测量计算方法和就地连通管水位计、电接点水位计使用多刻度标尺的优化建议。

According to problems existed in drum water-level measurement in large scal e boilers of thermal power plant, this paper analyzes the characteristic of diff erent measurements, puts forward a more accurate engineering measurement calcula tion, and suggests that multi-scale ruler be used for local connected pipes typ e water-level instruments and electrode type water-level instruments.
