Vibration occurs during the cold start of the thermal deaerator
Thread Content
A thermal deaerator uses steam entering from the bottom to heat water and remove oxygen; what is the reason for vibration and noise during cold startup? 1: When high-temperature steam comes into contact with low-temperature water, heat exchange occurs; the steam condenses, its volume decreases rapidly, and the surrounding water fills this reduced volume. The collision that results generates sound and vibration. 2: When high-temperature steam meets low-temperature water, it causes local water to vaporize, forming steam bubbles. When these steam bubbles come into contact with other amounts of low-temperature water, they burst, producing sound. Which of these two explanations is correct? ? Please explain it to me, thank you~
The second explanation is correct. When high-temperature steam comes into contact with low-temperature water, the local water rapidly vaporizes to form steam bubbles. As these steam bubbles move and collide with each other, they burst when they come into contact with cold water, generating sound and vibrations. This is a typical steam hammer phenomenon. .
I’ve never encountered such a situation before. Take your time; there’s no problem at all. Thank you for sharing this information, and thanks for your selfless dedication. Is there any good way to handle the issue of heat-induced salt instability in regenerated amine solutions? https://bbs.hcbbs.com/thread-5668900-1-1.html (Source: Haichuan Chemical Industry Forum)
