过热蒸汽管道热媒运行状态参数分析

Analysis of State Parameter in Pipeline with Superheated Steam

本文建立了过热蒸汽管道水力、热力计算的模型,并编写了计算程序,针对一根1200m长架空敷设的过热蒸汽管道,分别讨论了当管道内蒸汽流量、始端温度、始端压力、管径变化时,管道内温度、压力等参数沿程变化规律,以指导实际工程设计及运行。

This paper established the model of hydraulic and thermodynamic calculation in pipeline with superheated steam. It also wrote the computer program. Based on an overhead pipeline with the length of 1200 m, it analyzed and discussed the change rule of temperature and pressure in pipeline, when the steam flow, the temperature or the pressure of the pipeline head, the pipe diameter changed separately, with the purpose of giving some help to the designing and operating of practical engineering.
