Claims (1)

[Scope of Claim for Utility Model Registration] (1) A combustion part for burning fuel made of oil or gas is provided inside the vessel body having an air intake port and a hot air outlet, and the vessel body is provided with a combustion part that burns fuel made of oil or gas through the intake port from outside the vessel body. An oil or gas combustion heating appliance that heats the air taken into the body by the combustion part and then blows it out of the body from the outlet as warm air along with combustion gas, A fan is provided between the combustion section and the hot air outlet to generate negative pressure on the combustion section side, and the hot air is moved from the vicinity of the combustion section to the outlet by the fan. An oil or gas combustion heating appliance characterized in that a catalytic device having a catalytic body for purifying unburned components in the combustion gas is disposed in the path. (2) A catalytic device is composed of a heat-resistant container having at least two or more opposing surfaces that are porous, and a catalytic body held within the container. The oil or gas combustion heating appliance according to claim 1, which is inserted through an insertion port and installed in a catalyst device installation part provided in a path of hot air inside the vessel. (3) A filter attachment part is provided between the air intake port and the catalyst device in the body of the combustion heating appliance, and a filter for removing dust is attached to the attachment part, and a filter is attached to the outer surface of the body. The oil or gas combustion heating appliance according to claim 1 or 2, wherein the mounting portion is formed with a filter insertion port for mounting a dust removal filter. (4) The catalyst device has a structure in which a catalyst body is held in a heat-resistant container that has at least two or more opposing surfaces that are porous, with a large number of voids for ventilation, and is registered as a utility model. An oil or gas combustion heating appliance according to claim 1, 2, or 3. (5) The oil or gas combustion according to any one of claims 1 to 4 of the utility model registration claim, wherein the catalyst body is a carrier made of a ceramic honeycomb core and carrying a precious metal oxidation catalyst. heating equipment. (6) The catalyst body is a petroleum oil according to any one of claims 1 to 4 of the claims for utility model registration, in which a precious metal oxidation catalyst is supported on a carrier made of granular or fibrous activated carbon. or gas-fired space heaters. (7) The oil or gas combustion according to any one of claims 1 to 4 of the claims for utility model registration, wherein the catalyst body is a support made of granular activated alumina supporting a noble metal oxidation catalyst. heating equipment. (8) The catalyst body is a carrier consisting of a perforated plate having a large number of pores, on which a noble metal oxidation catalyst is supported, and is prepared in such a way that the pores do not overlap each other and the perforated plates do not come into close contact with each other. The oil or gas combustion heating appliance according to claim 1, 2, or 3 of the utility model registration claim, which has a laminated structure with a gap between the two layers.
