SYSTEM AND METHOD FOR INCREASING POWER OUTPUT FROM AN ORGANIC VAPOR TURBINE

Abstract:

A binary power plant system, comprising: a vaporizer for vaporizing an organic motive fluid circulating in a closed Organic Rankine Cycle (ORC) by a heat source fluid in heat exchange relation therewith and producing wet organic motive fluid vapor having a quality of at least approximately 80 percent; and a single organic vapor, turbine of said ORC: having an inlet for receiving the wet organic motive fluid vapor, wherein organic motive fluid vapor is expanded in said single organic vapor turbine without causing turbine blades of the turbine to be subjected to erosion.
