り簡易な構造とすることができる。When the flame holes 10 and the secondary air ejection passages 20 are alternately arranged, the secondary air is supplied to the secondary air ejection passages 20.
Since the supply path of the secondary air becomes complicated when the secondary air is supplied from both ends, a closing portion 23 is provided at the end of the secondary air ejection passage 20 on the carburetor 13 side, and the secondary air is supplied from the other end. By simplifying the supply path of the secondary air, the amount of the secondary air ejected from the secondary air ejection hole 21 is small in a portion near the inlet of the secondary air, large in a portion far from the secondary air, and uneven in the longitudinal direction. Become. Therefore, there is a method of increasing the cross-sectional area of the secondary air ejection passage 20 as a measure for equalizing the amount of secondary air ejection. However, this measure has a disadvantage that the entire combustor becomes large. By providing a rectifying weir 24 serving as an air resistance inside the
The amount of air ejected from the secondary air ejection hole 21 in the portion near the secondary air inlet of the secondary air ejection passage 20 is increased, and the secondary air can be supplied uniformly, so that the secondary air is uniformly supplied to the flame 25. The supplied and uniform combustion can be obtained. Further, the flame hole 10 and the carburetor 13 are connected to each other at the upper part of the mixing chamber 9, and the closing portion 23 is provided on the side of the carburetor 13 so that the closing portion 23 can be constituted by the side wall of the carburetor 13. And a simple structure can be obtained.
