WASTE HEAT RECOVERY SYSTEM USING ENGINE COOLANT OF VESSEL

摘要

PURPOSE: A waste heat recovery system is provided to reduce the capacities of a heater and a boiler by using the hot waste coolant discharged from an engine jacket of a ship as heating sources. CONSTITUTION: A waste heat recovery system comprises a generator engine(6), a heat exchanger for a generator, a plurality of heat exchangers(8), a heat recovery cooler(9), a heat recovery system circulating pump, and a heat recovery heater. The generator engine produces electricity required for a ship. The heat exchanger for a generator is mounted on the generator engine and cools a generator through heat exchange of clean water. The heat exchangers are installed in the generator engine and cool the generator engine through heat exchange of clean water. The heat recovery cooler is installed in the generator engine and delivers the heat of the hot cooling water passing through the generator engine to the heat recovery system. The heat recovery system circulating pump circulates the hot cooling water from the heat recovery cooler. The heat recovery heater heat-exchanges the clean water from the heat recovery cooler and supplies the heat-exchanged clean water to a place requiring a heating source.
