管壳式换热器安全阀最大泄放量的计算

Calculation of Maximum Relieving Capacity of Safety Valve on Tube & Shell Heat Exchanger

采用安全泄放装置是防止容器超压发生爆炸最有效的方法。运用流体在管道内作绝热流动的理论 ,结合气体膨胀因数 ,推导出一种更为严密的计算管壳式换热器安全阀泄放量的方法 。

Safety relief device is the most effective way to prevent vessel explosion due to excessive pressure. Using the theory of adiabatic flow of fluid in the pipe and the gas expansion factor, a more rigorous way for calculation of relieving capacity of tube & shell heat exchanger is derived. The calculation results have high accuracy.
