HI I am working on a project where PRV is currently taking 210 PSI steam and converting it to 10 PSI steam. This creates an energy loss
The customer is proposing taking existing 70 PSI steam from the exhaust end of an electricity-generating steam turbine to convert to 10 PSI steam instead with a new PRV.
What I’m unclear on: The 70-to-10 PSI steam PRV is expected to save 1400 MWh due to more steam being drawn through the turbine generator, increasing its output to the plant.
However, gas savings mentioned anywhere in the project documents even though it’s planned that the 210 PSI steam isn’t going to be used to make 10 PSI steam anymore. Are there actually no gas savings associated with this measure ?
