摘要
联合循环电厂余热锅炉中产生的水击现象能损伤或毁坏阀门和管道,甚至是管道的支撑。通常,余热锅炉的设计或部件是水击产生的罪魁祸首或催化剂。文中对此现象作了技术上的解释,并给出能够阻止其发生的一些实际方法。
In combined-cycle plants, water hammer events in their heat-recovery steam generator(HRSG) can damage or destroy valves, piping, and even piping supports. Often, an HRSG's design or component is the culprit or catalyst. Here's a technical explanation of the phenomenon and some practical steps to prevent it.
