Air-cooled water hammer in the sulfur tertiary cooler
Thread Content
Dear teachers, the third-stage cooler of our sulfur plant is designed to produce steam at 0.1 MPa; this steam is cooled by air cooling to become condensate, which then returns to the third-stage condenser for circulation. However, water hammer occurs in the air-cooled tube bundle. Has anyone encountered a similar problem? How was it solved? Thank you!
Has the return flow not entered the bottom of the sulfur cooler?

Yes, it’s very possible that the return is being blocked
This issue also exists in our device. The air cooler cannot be adjusted in real time due to the lack of variable frequency, resulting in the return water temperature fluctuating. At present, some preheating steam is supplied to the bottom of the three coolers; the return water is directed through drain pipes and connected to the condensate water network. Water hammer is avoided for now, but energy consumption has increased
If the condensate does not return to the liquid phase, installing a pressure-controlled valve at the outlet of the air cooler, but close to the condenser, can also solve the problem; it is worth checking whether this is the cause.
