PURPOSE:To allow a vaporizing flame of a uniform length to stably rise up by mixing an air mixed gas within a vaporizing cylinder with a combustion air to form a homogeneous air mixed gas and thereafter allowing the air mixed gas to flow into a gas chamber under an equalized pressure condition, and uniformly ejecting to burn the gas through a large number of gas ejection holes. CONSTITUTION:A vaporizing cylinder 106 is rotatably provided within a combustion cylinder 101 and an annular ejection passage 107 is made to communicate with a blasting chamber 102 through a number of vent pipes 108 penetrating through a gas chamber 105. Within the gas chamber inner than the perforated positions of gas ejection holes 104 of a combustion plate 103, an upward air mixing promoting cylinder 109, provided with a flat gas inlet chamber 110 the peripheral end of which is sealed between the cylinder 109 and the bottom wall of the combustion cylinder on the base end side and a downward mixing promoting cylinder 111, provided integrally with a wall cylinder 112 downwardly suspending from the combustion plate side and an overhang wall 113 extending the free end side of the wall cylinder outward, are disposed at a suitable interval, and a narrow bent air mixed gas passage 114 between the promoting cylinder 109 and the promoting cylinder 111. Further, an annular air mixed gas speed reducing ring 115 is extended from the inner wall of the combustion cylinder toward the inner side. |
