Can a extraction steam turbine achieve its rated power when operating in full condensation mode?

Our plant’s syngas compressors use extraction steam turbines, with a rated inlet flow of 77 t/h and a maximum extraction capacity of 40 t/h. Since the unit began operation, exhaust pumping has not been used as it operates in full condensation mode; the vacuum rewatering system is functioning properly. During normal production, the air intake flow rate is around 47 tons, and the compressor is operating within normal parameters. However, the pressure after the third stage of the turbine remains significantly higher than the design value by 1.6 MPa. Is there any problem with this type of turbine operating in a fully condensed state? Will it have an impact on the equipment?
