Steam condensate pressure
Thread Content
I would like to ask everyone: for low-pressure steam at 0.4 MPaG, does the condensate flow through the check valve not depend entirely on the back pressure? So there’s not much pressure, or can the maximum pressure reach 0.4 MPaG? I’m not sure if I understand correctly
In the absence of other relay pumps, it depends on the back pressure in the pipeline, which is generally low, but it also depends on the specific circumstances!
We have a condensate recovery pump behind us; the flash tank of this recovery pump operates at slightly positive pressure, so the pressure drop after the steam trap is very low. The pressure behind the steam trap must be lower than that of the steam; otherwise, the steam trap will not function!
