Abstract:
A steam cycle electric power generation system comprising:a heat source;a working fluid;a working fluid conduit having a plurality of fluid conduit sections;at least one set of first and second working fluid valves positioned on said working fluid conduit and selectively operable for opening and closing said working fluid conduit to flow of said working fluid;said working fluid conduit sections including a heat transfer section positioned between said set of first and second working fluid valves, said heat source adapted to input heat to said working fluid in said heat transfer section;an outlet section positioned downstream from said heat transfer section;an inlet section positioned upstream from said heat transfer section;said first valve operable to be opened before heat is added to allow said working fluid to flow from said inlet section into said heat transfer section;said set of first and second working fluid valves operable to be closed to isolate and thereby control the volume of a portion of said working fluid in said heat transfer section whereupon said heat source is inputting heat to said isolated portion of working fluid to raise the temperature and pressure of said isolated portion of working fluid in said heat transfer section; andsaid second valve operable to be opened after heat has been input to said isolated portion of working fluid by said heat source to allow said isolated portion of working fluid to flow from said heat transfer section into said outlet section.
