What to do if there are frequent fluctuations in the pressure of the hot water used for heating? What caused it?
Thread Content
The hot water pressure in the vapor phase is greatly affected by the catalytic stabilization system, including fluctuations in the feed rate to the stabilizer tower, fluctuations in the top pressure of the tower, and fluctuations in the temperature of the steam before it enters the heat exchanger at the bottom of the tower. Could the expert explain the specific reasons? ! !
Is there water in the stable gasoline, or is there a leak in the reboiler?
Generally, pressure fluctuations suggest a high likelihood of heat exchanger leakage. It is recommended to conduct regular tests and inspections of the heat exchanger.
No, I tried it yesterday by switching the stabilizer tank feed control valve to manual mode, and things stabilized a lot. That’s probably part of the reason.
The reboiler at the bottom of the tower is fine; it’s possible that there is a leak in some other heat exchangers.
