Lockbox flushing water heat exchanger
Thread Content
Gentlemen, has a lockhopper wash water heat exchanger been installed before the graywater from the lockhopper wash water tank enters the tank in your plant’s gasification unit? Exactly what temperature the graywater needs to reach in order for a heat exchanger to be used to recover heat. Please, fellow sailors, feel free to share your thoughts.
We’ve added it. Inlet temperature 79, outlet temperature 45.
Reply to 1# hzh005: We do not use a lockhopper for flushing the water heat exchanger here; the low-pressure ash water pump feeds directly into the lockhopper flushing water tank. The outlet temperature of the gray water pump is 45°C.
Our solution should be to lower the temperature of the graywater, I guess it’s to prevent cavitation in the sludge tank pump
We added it here, and it’s said that the effect isn’t very noticeable; it can also get clogged when the water quality is poor. .
