Gas is supplied inside, and at the same time, the gas ejected from the gas supply nozzle sucks air from the surroundings. The gas and air flowing into the mixing tube are mixed with each other in the mixing chamber 3 to form a mixture. A well-mixed mixture is
It is ejected into the primary combustion chamber 7 from the primary flame hole 5 and further ejected from the secondary flame hole 8. At this time, although not shown in the figure, when the air-fuel mixture ejected from the secondary flame hole 8 is ignited by some method, the size of the secondary flame hole 8 alone is ejected from the secondary flame hole 8. By setting the injection speed of the air-fuel mixture to be smaller than the combustion speed of the air-fuel mixture and setting the primary flame hole 5 so that it becomes larger, the secondary combustion flame flows inside the secondary flame hole 8 in the opposite direction. ignite, form a primary combustion flame 6 in the primary flame hole 5, and burn within the primary combustion chamber 7. Further, some of the unburned matter forms a secondary combustion flame 9 in the secondary flame hole 8 and burns.

なる。 As described above, in the burner 1 of the present invention, the flame hole installation body 4 formed into a hollow shape is provided with the primary flame hole 5, which uses the hollow portion as the primary combustion chamber 7, and the secondary flame hole 8 for secondary combustion. , and by making the size of the primary flame hole smaller than the size of the secondary flame hole, the primary combustion flame 6 and the secondary combustion flame 9 can be formed without flashback. , to burn. The combustion heat generated by combustion is
It is divided into a primary combustion flame 6 and a secondary combustion flame 9. The combustion heat of the primary combustion flame 6 heats the flame hole installation body 4 and changes into radiant heat. At this time, the primary flame holes 5 and the secondary flame holes 8 are arranged in a staggered manner, and the heat capacity of the flame hole installation body 4 on the secondary flame hole 8 side is made smaller than that on the primary flame hole 5 side. The radiation effect becomes larger.

の炎孔設置体からの輻射熱を増大させられる。 The burner of the present invention explained above has primary combustion,
By dividing into secondary combustion, some combustion heat can be used as radiant heat, and the other combustion heat can be used as convection heat.When considering combustion heat transfer, the total amount of heat transfer due to the coexistence of radiation and convection increases. In addition, since combustion is performed in two stages: primary combustion and secondary combustion, the secondary combustion flame becomes shorter. In addition, primary flame hole, secondary flame hole,
By configuring the primary combustion chamber as one unit, the number of parts is reduced compared to a configuration in which each part is molded and installed individually, resulting in cost reduction, and the flame hole is installed so that the heat of the primary combustion flame is the same. It will be transmitted through the body and heat the flame hole installation body with secondary flame holes,
Together with the direct heating of the primary combustion flame, the radiant heat from the flame hole installation body of the secondary flame hole can be further increased.
