Dear Sirs!!

Most steam turbine pressure control for combined cycle power plant is applied to sliding pressure control mode with condensing steam turbine.i.e steam turbine main control valve is wide open and the inlet pressure is determined by ST inlet steam flow rate.
So, is it possible to apply the sliding pressure control mode for non condensing steam turbine application of CC plant with desalination plant,i.e for back pressure steam turbine application?
For providing ST exhaust steam with constant pressure to desalination plant, The ST inlet pressure should be always operated with constant or fixed pressure mode for any part load case of gas turbine.

Please let me know above my question and related material if any
