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 rays having long wavelengths is disposed on an inside surface of the second transmission window.
摘要:
There are arranged a mixing room (4) for mixing fuel with air, flame ports (5) disposed downstream of the mixing room, an ignition plug and a flame rod disposed near the flame ports, and a catalyst layer (8) disposed downstream of the flame ports and bored with a plurality of communicating holes (8a). The operation includes steps of activating the igniting means (6) for forming a flame at the flame ports (5), extinguishing the flame after a predetermined time length by once stopping the fuel supply, and starting a catalytic burning reaction on the surface of the catalyst layer (8) by supplying fuel again without activating the igniting means (6). The operation is controlled in such a manner that, in the flame forming step at the flame ports (5), the burning is stopped when the ion current detecting means (7) does not detect a predetermined electric current, and, in the catalytic burning step at the catalyst layer (8), the burning is stopped, in contrast with the above, when the ion current detecting means detects the predetermined electric current.

In a pulse combustion apparatus, a plurality of identical pulse burners are employed such that a total amount of fuel to be burned is divided into equal amounts which are assigned to respective pulse burners. Either cushion chambers or tail pipes of the pulse burners are arranged to communicate with each other via one or more communicating passages so that interaction occurs in connection with pressure in the exhaust systems of the plurality of pulse burners. The interaction between combustion chambers causes the timings of combustion in the plurality of pulse burners to be synchronized, thus suppressing the occurrence of uncomfortable beat. In some embodiments, a sound-insulating mechanism is employed in each cushion chamber so that propagation of combustion sound to downstream side is effectively suppressed while the heat exchanging coefficient is simultaneously increased. In a further embodiment, sound-absorption materials are used in air pipes and air chambers of each pulse burner for effectively preventing propagation of combustion sound to upstream side.
