CATALYST COMBUSTION DEVICE

摘要

A catalyst combustion device, comprising a combustor (11), a fuel tank (12), a stop valve (13), and an ignition device (14), wherein the combustor (11) is formed of a gas nozzle (16), a suction air ejector (17), a mixing part (18), an igniting part (19), an ignition plug (20), a combustion chamber (21), combustion catalyst (22) stored in the combustion chamber (21), and exhaust ports (23), the mixing part (18) is formed as a straight cylindrical path, a cylindrical igniting part (19) in which an opening part (24) in its side surface communicates with the combustion chamber (21) is provided in parallel with the mixing part (18), burner ports (25) are arranged on the border between the mixing part (18) and igniting part (19), and the burner ports (25) are formed of a catalyst net (25a), whereby, because catalyst combustion occurs also on the catalyst net (25a) after a flame is formed on the upstream side of the combustion catalyst (22) and the combustion catalyst (22) is heated by the heat from the flame so as to increase the temperature to a catalyst combustible temperature, flame goes out by itself, the combustion catalyst (22) is allowed to start catalyst combustion, and the catalyst combustion can be made securely even when the combustion chamber (21) is formed thin, the thickness of a catalyst body can be reduced without lowering the combustion characteristics, and thus the height of a burner is allowed to be reduced so as to reduce the size and thickness of the catalyst combustion device.
