Abstract:
A catalytic combustion apparatus comprising:a fuel supply member for supplying a fuel; an air supply member for supplying air; a premixing chamber for mixing the fuel supplied from the fuel supply member and the air supplied from the air supply member to make a mixed gas, the mixed gas flowing from the premixing chamber in a downstream flow direction; a catalytic element including two opposing surfaces and a porous member for catalytically combusting the mixed gas and emitting radiant heat; a combustion chamber provided downstream of the premixing chamber, having two opposing side walls facing each other and each having a longitudinal dimension along the flow direction, one of the opposing side walls including a first radiated heat receiving member, and in the other of the opposing side walls including a second radiated heat receiving member and the catalytic element disposed within the combustion chamber, wherein said first radiated heat receiving member is facing one of said two opposing surfaces of said catalytic element and said second radiated heat receiving member is facing the other of said two opposing surfaces, wherein said first and second radiated heat receiving members are provided with ducts tightly adhered thereto and incorporated therein, and a heating medium is provided to flow within the ducts and wherein said heating medium is used in an exterior of said catalytic combustion apparatus, and a second catalytic element in the shape of a plate having a porous member disposed at an outlet of the combustion chamber, and adjacent a downstream end of said second radiated heat receiving member, to enhance heat exchange between said second catalytic element and said second radiated heat receiving member.
