About water hammer problem in heat exchanger

2009-02-28View Original

Thread Content

In the petrochemical process, if the heat exchanger temperature is too high, water hammer will easily occur, which will cause great damage to the heat exchanger. But what I don't understand is what temperature can cause water hammer in the heat exchanger? I am a craft student and know nothing about equipment, so I forgot all the advice from you guys. Thanks!

Water hammer in the heat exchanger is caused by the steam hitting the cold medium in the heat exchanger. The cold medium instantly absorbs the heat of the steam. Some of the surrounding steam condenses into water, and the subsequent steam will hit it at high speed, forming a shock wave in the heat exchanger and making noise. It usually occurs during the initial start-up stage after driving or repairing. In addition, excessively high condensate water level in the heat exchanger may also cause water hammer. Generally, this can be solved by increasing the condensate water discharge. You can also pause the steam and discharge the condensate water before adding steam.

The answer above makes sense, let’s learn together* Got it

Upstairs, you are too obvious!

To avoid water hammer, you only need to introduce steam (the steam valve cannot be opened wide at this time) and drain the condensate, which is what we call heating equipment. When the temperature of the equipment comes up, or the condensate does not drain out, just open the steam valve wide again.

In other words, the water hammer phenomenon of the heat exchanger generally only occurs when it is first put into use or just started? After the heat exchanger operates smoothly, water hammer generally does not occur?

Water hammer also occurs during operation, which is usually solved by increasing drainage and adjusting steam flow.

Would connecting a condensate tank directly under the heat exchanger completely solve the water hammer problem?
