<p>The present invention relates to an apparatus for re-combusting combustion exhaust gas placed between a burner and a heating unit heated by or exchanging heat with combustion gas generated from the burner, and re-combusts combustion exhaust gas discharged after heating or exchanging heat with the heating unit. The apparatus comprises: an intake duct and an exhaust duct placed to be spaced from each other, containing the combustion exhaust gas discharged from the heating unit and introduced thereinto and discharged therefrom respectively; a re-combustion duct interconnecting the intake duct and the exhaust duct, re-combusting the combustion exhaust gas introduced into the intake duct, and guiding the combustion exhaust gas into the exhaust duct; a heat storage plate placed between the intake duct and the exhaust duct to pass the combustion gas generated from the burner therethrough, storing the heat of the combustion gas to provide the stored heat to the re-combustion duct; and a catalyst unit placed on the inner peripheral surface of the re-combustion duct, and oxidizing and re-combusting the combustion exhaust gas heated by the heat provided from the heat storage plate and passed through the re-combustion duct.</p> |
