1.0MPA steam pressure drop
Thread Content
I would like to ask why, when the steam pressure drops to 1.0 MPa, it is necessary to increase the speed of the exhaust fan wheel and use drain lines to cool the steam lines
The steam pressure drops, making it prone to carrying water.
The pressure has dropped and the temperature has fallen; condensate needs to be drained
It is mainly to prevent water from entering, as well as to avoid the impact that water can have on the equipment once it gets in!
When the steam pressure is low, the steam temperature drops, increasing the likelihood of liquid contamination in the steam; therefore, condensate must be removed
This is the theory, but in practice there is no need to start draining condensate just because the steam pressure drops a little
If it’s much higher than the temperature of saturated steam, there’s no need to turn it on
