A combined cycle steam turbine including a system for providing process extraction steam includes a control system for counteracting the thrust effect of the steam extraction flow at the exhaust of the high pressure section of the steam turbine. The control system includes a valve and piping arrangement for diverting HP exhaust packing leak-off steam from a lower pressure stage to a higher pressure stage of an intermediate pressure section of the steam turbine.
