大管径管道含水瓦斯混气准确计量的研究与应用

Research and Application of Accurate Measurement of Water-bearing Gas Mixture in Large Diameter Pipe

瓦斯发电厂的瓦斯输送管道一般为大管径管道,输送的瓦斯气含空气及大量水分。为此,由气体超声流量计、激光CH_(4)浓度传感器、瓦斯折纯积算仪等构建了一套瓦斯计量系统,适用于大管径管道、含水瓦斯混气的准确计量,解决了供需双方在贸易结算上遇到的难题。

Gas transmission pipelines in gas power plants are generally large diameter pipes. The gas conveyed contains air and a large amount of moisture. For this reason, a brand new gas measurement system was constructed by gas ultrasonic flowmeter, laser methane concentration sensor, gas refractometer, etc.which is suitable for accurate measurement of large diameter pipelines and water-containing gas mixture,and solves the problem of both supply and demand side encountered in trade settlement.
