Abstract
A catalytic combustor utilizes radioactive heat with a high efficiency, has a radiation wavelength distribution rich in visible ray components, and is excellent in complete combustibility and visual confirmability even in a standby combustion condition. The present invention forms a thin film coat of metal or metal oxide which transmits rays having short wavelengths and reflects rays having long wavelengths on a surface of a transmission window disposed opposite to an upstream surface of a catalyst body. The catalyst body is composed of a metal wire structure having a high aperture ratio and is disposed in a combustion chamber. Furthermore, an auxiliary catalyst body which has a high aperture ratio and a small capacity is disposed in the vicinity of a mixed gas injection port at a location in contact with the mixed gas when the flow rate of the mixed gas is less than a predetermined value. Moreover, a freely openable/closable cover having reflectivity to heat rays is disposed in the vicinity of an outside surface of the transmission window. An air flow path is formed between the transmission window and a second transmission window. Also a thin film coat reflecting radioactive heat …
