PURPOSE:To realize a constantly stable ejection of flame jetted from a burner, by a method wherein a hole is formed in a guide part which guides the flame jetted by the burner toward the inside of a combustion chamber by a prescribed length, on a burner side with respect to a flange part which protrudes sideway from the guide part. CONSTITUTION:A guide part 41 guides a flame jetted from a burner 23 by a prescribed length, a flange part 42 protrudes from the guide part 41 sideway in a direction making the right angle with an axial direction, a through-hole 43 is opened in the guide part 41 on a burner side with respect to the flange part 42, and a mixing zone 44 is formed at a tip end of the guide part 41. The mixing zone 44 is for mixing air flowing from the through-hole 43 with the flame. If a flame stabilizing means 40 comprising the guide part 41, the flange part 42, the through-hole 43 and the mixing zone 44 is provided on a heat exchanging member 22 which is mounted on a wall of a combustion chamber 21, an assembling of the burner 23 is improved and mounting strength may become preferable. |
