A valve 10 is provided between the cylinder 8 and the nozzle 9 to control the flow rate of the fuel gas supplied from the cylinder 8. The fuel gas ejected from the nozzle 9 sucks the surrounding air by the attraction of the gas flow, is uniformly mixed in the mixing chamber 11, and is supplied to the combustion chamber 12. The combustion chamber 12 is provided inside a heat generating portion 13 formed of a metal casing such as aluminum, and has a fin 14 from the heat generating portion 13 toward the inside. The catalyst 15 obtained in the present embodiment is installed on the inner wall surface of the combustion chamber 12 in close contact therewith. Next, the operation principle will be briefly described. First, when the heater 16 is heated, a part of the adjacent catalyst 15 becomes high in temperature and reaches a sufficient activation temperature, the valve 10 is opened, the fuel gas is supplied from the nozzle 9 to the mixing chamber 11, and at the same time, the air is also discharged. Supplied by attraction. The fuel gas and air are introduced into the combustion chamber 12 via the mixing chamber 11 and start catalytic combustion from the activated catalyst 16 near the heater 16, and the reaction gradually spreads to the entire catalyst 15 in the combustion chamber 12,
The combustion gas is discharged from the exhaust port 17. Reaction heat is provided from the inner wall surface of the combustion chamber 12 where the combustion exhaust gas (convection) is in contact with the catalyst 15 to the outside (heat transfer) via a metal casing. Air excess ratio (air / fuel) 1.0 using isobutane as fuel
The conditions were set to 5,500 kcal / h, and the combustion rate was determined from the exhaust gas characteristics (HC, CO). As a result, in the example according to the present invention, a combustion characteristic with a combustion rate of 95% or more was obtained.
