PURPOSE:To prevent the titled burner from generation of blow-out extinguishment by a method wherein the mixing a vaporized gas with a forced air-flow is more accelerated by a stirring mixing, the capacity of a gas chamber is made to be increased, further, the flow velocity of mixed gas introduced into the gas chamber is reduced. CONSTITUTION:An annular speed reducing gas passage 23 is formed between a recessed part 4 and the top end side of a flame blowing-off guide cylinder 22 at the introducing side position of a gas chamber 20, accordingly, the flow velocity of a mixed gas from a vaporizing cylinder 8 is reduced at the gas passage 23, then the gas is introduced into the gas chamber 20 with slow flowing velocity. Therefore, the mixed gas is accumulated under the constant pressure condition at anywhere, then blown-off per uniform blowing-off quantity with uniformly slow blowing-off speed through many gas blowing-off holes 17, 18 perforated on a cylinder wall side burning surface 15 and a bottom wall side burning surface 16. Thereby, the generation of blow-out extinguishment can be prevented, also the vaporizing and burning noise can be reduced to the utmost. |
