WASTE HEAT RECOVERY SYSTEM FOR A MARINE VESSEL

摘要

The present invention relates to a waste heat recovery system for a ship. The waste heat recovery system for a ship comprises: a ship propulsion engine; an exhaust gas recovery vessel which is connected to the engine; a hot well which has a heating pipe allowing hot water to flow and penetrating the recovery vessel, both ends of the heating pipe being connected outside the recovery vessel; a waste heat recovery generation unit which includes a reaction turbine which has an evaporation pipe allowing an operation fluid for power generation to flow and penetrating the recovery vessel, is connected to one end of both ends of the evaporation pipe coming out of the recovery vessel, receives the operation fluid from the evaporation pipe, and is rotated by propulsion force of the operation fluid emitted radially from the center axis, a condenser which receives the operation fluid discharged from the turbine, and one or more compression pumps receiving the operation fluid from the condenser and compressing the received operation fluid to send the compressed operation fluid to the other end of both ends of the evaporation pipe. Preferably, the heat of the condenser is reused by a separate heat pump for hot water and heating, the waste heat recovery system can be used as a heat pump in which a cooling cycle of a cooler in a ship using the cooler preheats an operation fluid of a power generation unit, and thus it is possible to optimally recover the waste heat.
