COMBUSTION APPARATUS HAVING AIR INTAKE PREHEATER

WIPO Patent Application WO/2014/112740

A1

The present invention relates to a combustion apparatus capable of reducing the combustion load of a burner and improving the combustion efficiency thereof. The combustion apparatus includes: a premixing chamber for premixing external air, introduced through an air supply inlet, with a combustion gas; a blower for supplying a mixed air premixed in the premixing chamber toward a burner; a combustion chamber for burning the mixed air by ignition of the burner; a heat exchanger for heat exchange with room heating water by using the combustion heat of the combustion chamber; an exhaust gas discharging part for discharging an exhaust gas having passed through the heat exchanger; and a duct through which the exhaust gas having passed through the exhaust gas discharging part is discharged outside, wherein the combustion apparatus comprises an air intake preheater for heat exchange between the exhaust gas discharged to the duct through the exhaust gas discharging part and the air supplied to the premixing chamber through the air supply inlet, the air intake preheater including a channel-forming member in which a plurality of unit plates are stacked with a predetermined interval therebetween to form an exhaust gas channel and an air intake channel therein that are separated from each other, are adjacent to each other, and are alternately arranged.
