As the demand for horsepower on the CGC increases, it will be necessary to switch from a fully condensing mode of operation for the turbine to an extraction/condensing mode. This is achieved by gradually closing the internal extraction valves of the turbine while simultaneously opening the turbine’s inlet throttle valves. These two sets of valves can be used to regulate both the turbine speed and the pressure in the extraction steam header.

When the CGC (which is presumably a compressor) needs more horsepower, it is necessary to switch the turbine’s full condensation mode to a steam extraction/condensation mode. The switching operation involves slowly closing the steam extraction valve inside the turbine while opening the speed control valve inside the turbine. These two sets of valves can be adjusted back and forth to regulate the turbine speed, thereby also adjusting the pressure in the extraction steam main.
