Back pressure steam turbines STG II. These are double-shaft turbines with a high-pressure and low-pressure STG I module, which are connected in series and suitable for double-pressure steam boilers, as they allow steam to be supplied to the turbine at two pressure levels. They are equipped with one turbine stage on each shaft.

22/5/2019 · Back-pressure turbines expand the live steam supplied by the boiler to the pressure at which the steam is required for the process. The exhaust pressure is controlled by a regulating valve to suit the needs of the process steam pressure. Back-pressure turbines are commonly found at refineries, district heating units, pulp and paper plants, and

The steam turbine in the GTCC can be extraction-condensing steam turbine (ECST) (Figure 20a) or back pressure steam turbine (BPST) (Figure 20b). In the ECST, steam is expanded from inlet pressure (say at 100 bar) and high temperature (up to 538 ο C) to the condenser pressure (about 10 kPa) below atmospheric pressure.
