ABSTRACT:
An electrical generating system in which exhaust steam from the turbine is recycled through the turbine to reduce feedwater requirements and condenser complexity. The turbine is an axial flow dual shaft compressor/turbine unit in which a coaxial shaft couples the turbine section to the compressor section. A portion of the energy extracted from the steam is used to power the generator and the remainer is used to power the compressor. The turbine exhaust steam is directed through compressor section and the compressed steam is then mixed with turbine inlet steam by a steam jet ejector. The compressor may be powered from either one or both shafts from the turbine.
