PURPOSE:To regulate a combustion air amount by opening a damper plate through a bellows-sliding motion plate-sliding motion axis with a volumetric expantion of a liquid or gas in a detecting pipe proportional to a temperature rise of an upper portion of a combustion cylinder caused by a flame due to an excessive vaporized gas. CONSTITUTION:An excessive vaporized gas is burned with flame at the upper ends of an inner flame cylinder 1 and an outer flame cylinder 2. A liquid or gas filled in an inside of a detecting pipe 10 is expanded volumetrically when the former is heated, a bellows 11 mounted at an end 10' of the detecting pipe 10 air tightly is biased, a sliding motion plate 13 with a sliding motion axis 12 is displeased, a damper plate 15 mounted on an end of the sliding motion axis 12 is depressed downward correspondingly to its displacement, an air opening 5' in a lower side plate 5 of the inner flame cylinder is expanded, an entering amount of an air from here is increased, a combustion air is increased and supplied through a flame hole of the inner flame cylinder 1 correspondingly to an increasement of the air, and a combustion under an excessive vaporized gas condition is modified to a better condition. |
