Direct heat exchange between steam and water
Thread Content
How is direct heat exchange between steam and water carried out in such a way as to avoid water hammer? How should it be calculated?
The steam pipe is inserted horizontally at the bottom of the water tank, and many small holes are made in the part of the steam pipe that is inside the tank. However, there will still be some water hammer.
When steam is condensed into a liquid, its volume shrinks drastically, and it seems difficult to avoid water hammer. However, this water hammer effect can be reduced to a minimum by following the method suggested on the second floor: the nozzles should be made smaller and more numerous, which will result in smaller fluctuations. For reference.

There are professional submersible soda mixers; we use those with hot water tanks, and water hammer can basically be ignored
