れ、燃焼装置をコンパクトにできる。Here, when the combustion amount of the combustion device is reduced to a small value, in the case of a conventional combustion device, the flame enters the holes of the porous flame holes to heat the flame holes, and the flame holes become red hot. The temperature is about to rise. However, in this embodiment, the air-fuel mixture ejection passage 26 having the flame holes 25 is divided into a plurality of rows,
Since the secondary air ejection passages 28 are provided along each other, the heat of the flame holes 25 is bent so as to be a part of the constituent parts thereof so as to come into close contact with the peripheral wall of the secondary air ejection passages 28. From the part that is installed alongside, it is escaped to the peripheral wall of the secondary air ejection passage 28 and is cooled by the secondary air passing therethrough, so that the temperature rise of the flame hole 25 is prevented and the heat deformation of the flame hole 25 itself is prevented. The clogging of the flame holes 25 due to soot generation due to the backfire into the mixture gas ejection passage 26 in the flame holes 25 is prevented, and the durability of the combustion device is improved. Further, since the periphery of the flame 31 is cooled by the secondary air from the secondary air ejection holes 27, the flame
The radiant heat of 31 is reduced, and the temperature rise of the flame hole 25 can be prevented. Further, since the mixed jet passage 26 is formed between the secondary air jet passages 28, the air-fuel mixture flowing along the outer peripheral wall of the secondary air jet passage 28 is cooled and the surface of the flame hole 25 where the fire 31 is formed is cooled. The temperature on the opposite side can be lowered, the temperature difference in the plate thickness of the flame hole 25 can be enlarged, and flashback can be prevented. Since it is possible to prevent the temperature of the flame holes 25 from rising, it is possible to expand the range in which the combustion amount of the combustion device can be made small and variable. 2 from the secondary air outlet 27
Since the flame 31 is finely divided by the secondary air and the secondary air is sufficiently supplied, combustion is promoted, the flame length is shortened, and the combustion device can be made compact.
