本文对LFX型蒸汽流量计示值受蒸汽干度的影响作了定性分析和试验,初步证明仪表示值基本上是湿蒸汽中干饱和蒸汽的质量流量。文中还介绍了为满足能源计量的要求,应如何计算饱和蒸汽传递的热能的方法。
This paper qualitatively analyzes and tests the indication of LFX-type steam flowmeter by the influence of steam dryness, and initially proves that the indicator value is basically the mass flow of dry saturated steam in wet steam. The article also describes how to calculate the heat transfer from saturated steam to meet the energy metering requirements.
