Thanks for the reply,
I don't know that all the posssible causes of water hammer have been investigated, but this has been a long standing practice(before my time). I do know that at one time we gradually lowered the tank pad pressure to see how low we could go, and the higher temperature...
Thanks for the replies. As for the flasing problem, this occurred in some of the higher temperature return lines to the tank whenever the tank pressure was lowered. When pressure is maintained in the tank vapor space at 30 psig or above, the flashing does not occur. The return temperatures run...
We have a condensate collection tank that receives clean condensate from a number of processes throughout the plant, prior to being pumped through polishing filters and on to the deaerator. The condensate returns are pumped from each department at various temperatures depending on process...
