Latent Heat Recovery Generator System

Abstract

A heat recovery generator system ( 1 ) includes a boiler ( 11 ) converting water into high-pressure steam that passes through a steam pipe ( 12 ), a turbine ( 13 ), a first pipe ( 10 ), a condenser ( 15 ), and a second pipe ( 102 ) in sequence. The steam condenses into water after passing through the condenser ( 15 ). The condensed water passes through a water pump ( 16 ), a water supply pipe ( 17 ), and a heater ( 18 ) to the boiler ( 11 ). A latent heat recovery device ( 2 ) includes a compressor ( 21 ) that outputs a coolant moving along a coolant pipe ( 22 ) passing in sequence through a first heat exchanger device ( 23 ) and a second heat exchanger device ( 25 ) and then returning to the compressor ( 21 ). A third pipe ( 103 ) branches from the first pipe ( 101 ) and is connected to a fourth pipe ( 104 ) via the second heat exchanger device ( 25 ). The coolant absorbs heat from the steam via the second heat exchanger device ( 25 ). Heat recovery water absorbs the heat released from the coolant through the first heat exchanger device ( 23 ).
