APPARATUS FOR GENERATING HOT WATER REUSING THE EXHAUST GAS HEAT

摘要

A water heater for recycling exhaust heat is provided to increase a recycling rate and to adapt to existing equipment discharging the exhaust gas by exchanging heat in a flowing path of a chimney and in an inner space of the gas exhaust pipe. A water heater for recycling exhaust heat, using heat energy flowing a gas exhaust pipe(202) and a chimney(201) successively from equipment discharging the exhaust gas, comprises the followings: a chimney heat exchanger installed in a exhaust gas flowing path of the chimney, to exchange heat using heat energy of the exhaust gas passing the chimney; an exhaust pipe heat exchanger(21) installed in the gas exhaust pipe, to exchange heat using heat energy of the exhaust gas passing the gas exhaust pipe; a storage tank(23) storing separately heat exchanging water to supply to the chimney heat exchanger and heat exchanged water from the exhaust pipe heat exchanger; a water supplying unit(25) to the chimney heat exchanger supplying the heat exchanging water stored in the storage tank to the chimney heat exchanger.
