Changes in steam consumption for compressor turbines
Thread Content
As the title indicates, the parameters for the medium-pressure steam used to drive the compressor turbine in a normal design are 3.8 MPa and 450 degrees； What is the impact on the turbine if it is driven by superheated steam at 3.8 MPa and around 370 degrees? What pattern does the change in steam consumption follow?

To prevent water hammer from damaging the hydraulic turbine impeller, i.e., the saturation temperature above 3.8 Mpa! At low temperatures, the energy level is relatively low, so more material is required. The material properties also need to be taken into account. Raising the steam temperature will increase the energy consumption as well. If all other parameters remain unchanged and only the temperature changes, more material will be needed at lower temperatures!
This can be checked with the device manufacturer for an estimate. It is possible to calculate how much the steam volume can be reduced, as well as whether it has an impact on the long-term operation of the equipment
