Title:
CATALYTIC COMBUSTOR
Document Type and Number:
WIPO Patent Application WO/1997/048945
Kind Code:
A1
Abstract:
In order to obtain a catalytic combustor having a high radiation heat utilization efficiency, a high economic efficiency, and a radiation wavelength distribution abundant in visible light components, and being excellent in the complete combustibility, which is kept stable even in a stand-by combustion state at a low combustion rate, and in the visual ascertainability, the surface of a heat ray transmittable window which is opposed to an upstream side surface of a catalyst is coated with a thin film of a metal or a metal oxide which transmits short wavelength light therethrough and reflects long wavelength light thereof. In a combustion chamber provided with a catalyst in a downstream side region and a heat ray transmittable member on a side wall, a metal catalyst comprising a metal wire rod of a large numerical aperture is provided so that one end thereof is set close to the catalyst with the other end thereof directed toward an upstream side portion of the combustion chamber. An auxiliary catalyst of a large numerical aperture and a small capacity is also provided in a position, which is in the vicinity of a gaseous mixture ejection port, in which the auxiliary catalyst contacts a stream line occurring when the amount of the gaseous mixture becomes not higher than a predetermined level. A heat ray reflecting openable cover is provided close to an outer surface of the transmittable window. An air flow passage is provided between the transmittable window and a second transmittable window, the inner surface of which is coated with a long wavelength radiation heat ray reflecting thin film.
