Chang, Y P

A thermal power plant having multi-staged steam turbines and heat exchangers therebetween, each heat exchanger extracting heat from the supply to an upstream stage for adding heat to the supply of the next successive downstream stage; a portion of the supply to the last downstream stage being diverted through a heater for adding heat to the feedwater flow to a boiler. Additional heat exchangers may be provided between stages for utilizing the feedwater to cool the working steam. One form of heat exchanger is provided with a plurality of axially spaced annular chambers having vortex flow producing means adjacent the inner peripheries thereof; whereas another form of heat exchanger is provided with a helically finned interior chamber in fluid communication with upstream guide vanes for inducing vortex flow.
