Class Р.1: single-casing back-pressure turbines with a straight steam flow in thecasing. Capacity range is from 25 MW to 80 MW, live pressure is from 4.5 to 12.8 MPa (45-130 kgf/cm2). The turbine exhaust can be organized both for industrial header and for heat extraction generations. The front and rear bearings are made in the remote separate bodies resting on the proper foundation frames. The turbine features the possibility to organize single-stage controlled heat extraction with a capacity of up to 150 Gcal/h (backpressure), as well as controlled and uncontrolled industrial steam bleeding for auxiliaries with a capacity of up to 200 t/h.
