Waste heat recovery device for a marine vessel

摘要

A waste heat recovery device for a marine vessel is disclosed. According to the embodiments of the present invention, the waste heat recovery device for a marine vessel includes: a heat exchanger, which recovers heat from the exhaust fumes discharged from the engine, to heat a first refrigerant under uniform pressure; a turbine which is driven by adiabatically expanding the first refrigerant heated under uniform pressure; a condenser which condenses the adiabatically expanded first refrigerant; and a heat exchanging pump which compresses the condensed first refrigerant so as to re-circulate the compressed first refrigerant to the heat exchanger.

主权项

1. A waste heat recovery device for a marine vessel, the waste heat recovery device comprising:
a heat exchanger configured to recover heat from an exhaust fume discharged from an engine and heating a first refrigerant under uniform pressure; a turbine configured to be driven by adiabatically expanding the first refrigerant heated under uniform pressure; a condenser configured to condense the first refrigerant adiabatically expanded; a heat exchanging pump configured to compress the first refrigerant condensed, to be re-circulated in the heat exchanger; and a turbo charger configured to be operated by the exhaust fume, wherein the heat exchanger comprises a heat exchange portion arranged between the turbo charger and the turbine and configured to perform heat exchange between an exhaust fume discharged from the turbo charger and the first refrigerant supplied to the turbine, wherein the heat exchange portion comprises:
a first heat exchange unit configured to perform heat exchange between the exhaust fume discharged from the turbo charger and heat of the heat transfer fluid; anda second heat exchange unit configured to perform heat exchange between exhaust fume discharged from the first heat exchanger and the first refrigerant supplied to the turbine.
