The mixed gas flow velocity is also uniform, which can form a combustion flame free of deformation and improve the exhaust gas performance, and can prevent the temperature of the outer net from rising due to the formation of a local contact flame. The heat resistance of the outer net can be improved.

The same parts as those of the conventional example will be denoted by the same reference numerals and description thereof will be omitted, and only different parts will be described.
Reference numeral 10a is a pressure equalizing cylinder having a lower opening tubular shape provided in the flame holding plate 5, and has a plurality of holes in the ceiling and the peripheral wall portion, and the lower opening edge is formed on the inner peripheral flat surface portion 5a of the flame holding plate 5 with screws 6a. It is installed. Reference numeral 8a is a bolt caulked and fixed to a substantially central portion of the ceiling of the pressure equalizing cylinder 10a.After the burner lid 12 and the burner cap 13 are passed through the bolt 8a, a nut 14 is screwed to the pressure equalizing cylinder 10a to remove the burner lid. 1
2. The burner cap 13 is fixed.

し燃焼を行う。With the above configuration, fuel and combustion air are jetted from the nozzle 3 and the throat 4 into the vaporization cylinder 1 that has been heated by the sheath heater 2 in advance. Then, the vaporized premixed gas of fuel and air passes through the opening 5b at the bottom of the flame holding plate 5 and is sent into the pressure equalizing cylinder 10a. The premixed gas in the pressure equalizing cylinder 10a passes through the side surface of the pressure equalizing cylinder 10a and a plurality of holes provided in the upper surface and is ejected from the flame holes 7 on the side surface of the flame holding plate 5a to form a flame and perform combustion.

害物が局部的に存在しないことになり、保炎板５内での
混合ムラがなくなり、均一な火炎の形成が実現できる。Here, since the bolt 8a for fixing the burner lid 12 and the burner cap 13 is located above the substantially central portion of the ceiling of the pressure equalizing cylinder 10a, the bolt is located near the inner peripheral surface of the flame stabilizing plate 5. In comparison, the burner can be downsized in the radial direction, and obstacles such as the conventional bolt 8 are not locally present near the inner peripheral surface of the flame holding plate 5, so that the inside of the flame holding plate 5 can be prevented. It is possible to realize uniform flame formation by eliminating the uneven mixing.
この為、燃焼排ガス性能が向上し、かつ局部的な火炎の
密着による外網の赤熱高温化を防止し耐熱性に富んだ、
安全性の高い燃焼装置を得ることができる。Therefore, the combustion exhaust gas performance is improved, and the red net temperature of the outer net is prevented from rising due to the close contact of the local flame, and the heat resistance is excellent.
A highly safe combustion device can be obtained.
