PURPOSE:To constitute the titled burner so that remaining unburnt gas does not come out of an apparatus, by a method wherein the remaining unburnt gas is burnt up by electrifying a heater at the time of suspension of combustion. CONSTITUTION:A fire extinction heater 10 is so constituted that it is positioned within evaporation gas of fuel in the inside of a mixing tube 6, electrified at the time of extinction of the fire and remaining unburnt gas at the time of the extinction of the fire is burnt up. In other words, the remaining unburnt gas to be generated at the time of the extinction of the fire when combustion is suspended is burnt up in the inside of the mixing tube 6 by the fire extinction heater 10 which is electrified for a fixed period of time directly after fire extinction operation and is red-hot at the high temperature and HC and a fire extinction foul odor are not made to generate. Even if a lot of unburnt gas is generated by a method wherein timing closing a nozzle 5 is delayed or the nozzle 5 is not closed completely always by an evaporation solenoid valve 9 by adhering tar to the nozzle 5, the unburnt gas is burnt up in the inside of the mixing tube 6, and HC and a fire extinction fuel odor are not made to generate. |
