Testing of the boiler water is important to determine that: ![]() State with reasons why the testing and treatment of boiler water is essential ? Water hammer is avoided by slowly admitting the steam into the cold line, and draining/venting the cold line to minimise the vacuum forming, and assist in draining the condensate. State how the risk of water hammer may be avoided ? This impact force can be high enough to rupture the pipeline. This vacuum causes the water plug to be drawn into the closed end of the pipe with increasing velocity producing high impact forces on the pipework. ![]() The steam condenses producing both water, and a vacuum (when the water seals the pipeline from the steam supply). ![]() ![]() Water hammer occurs when steam is admitted into a cold pipeline. Questions and Answers for Marine Engineers – Part 1 Explain the term water hammer indicating possible effects on the system ?
