PURPOSE: To enable uniform combustion of a mixture gas, by a method wherein an exhaust chamber connected to an enclosed combustion chamber covering a wire netting-shaped burner port part is mounted, a pressure averaging plate is located therebetween, and a catalyst is placed in the exhaust chamber.
CONSTITUTION: The inside of a casing 1 of a hot air tape space heater consists of a rod-form burner 2 formed in a semicircle in cross section, a primary air port 4, a mixing pipe 5, a mixture gas chamber 6, a burner port part 7 made of a wire netting and an enclosed combustion chamber 8 for preventing entrance of a secondary air. A pressure averaging plate 10 is located between the combustion chamber 8 and an exhaust chamber 9 connected thereto, and a catalyst 11 is positioned at the upper part of the exhaust chamber 9. The gas jetted through a gas nozzle 3 sucks the air required for combustion through a primary air port 4, the gas enters the mixture gas chamber 6 through the mixing pipe 5 and is jetted into the combustion chamber 8 through the burner port part 7. Simultaneously, the gas is ignited for surface combustion, but combustion of the mixture gas is averaged by the action of the pressure averaging plate 10 and the catalyst. This permits the prevention of worsening of combustion.
