Description

[Detailed Description of the Invention] This invention relates to a burner, and more specifically to a burner in which a flame-transfer member that transfers flame between a plurality of combustion plates constituting a cylindrical burner can be positioned reliably.

The present invention will be explained in detail below with reference to drawings showing an embodiment of the present burner. In FIG. In the example, there are four combustion plates, each of which is configured in a cylindrical shape, and the seam between the combustion plates 2 is in the direction of the axis C of the cylindrical shape.

Reference numeral 4 denotes a seam presser plate which abuts the seam from the outside and serves also to hold the seal member 5 between the combustion plates 2, as seen in FIG.

Reference numeral 7 denotes an end holding member that presses the end of the combustion plate 2 in the axial direction, the lower end in this embodiment, and its rising portion 8 holds the combustion plate 2 in place. Again, it also serves to retain the sealing element 9 at the end of the combustion plate 2, as shown in FIG. This end holding member 7
is attached to the base 6 with screws 10 or the like. Reference numeral 11 denotes a recess into which the seam presser plate 4 is fitted, and a protruding engaging portion 12 is provided here.

Reference numeral 13 denotes a fire transfer member that straddles the joint presser plate 4 and extends to the combustion plates 2, 2 on both sides thereof, and has a U-shaped cross section, one end plate 15 forming a closed end 14, and the other end The opening end 16 is formed. Reference numeral 17 denotes an engaging portion that cooperates with the engaging portion 12 of the end holding member 7. Since the engaging portion 12 has a protruding shape, the two engage with each other as a concave shape, and the fire transfer member 13 is held at the end. It is designed to be positioned in a recess 11 for the presser plate 4 of the presser member 7. 18 is an exhaust port, and 19 is a relief part of the presser plate 4.

20 is the outlet of the flame 21 from the pilot burner.

The main story is as described above, and the pilot's flame 2
According to No. 1, the combustion plate 2 on the front side is ignited, and the flame is transferred to the adjacent combustion plate 2 by the flame transfer member 13, but at this time, unburnt gas flows from the combustion plate where the closed end 14 of the flame transfer member 13 is located. When it accumulates in the fire transfer member 13 and comes out from the open end 16, it catches fire from the burning plate where the open end 16 exists and transfers the fire to the unburned plate. Therefore, in FIG. 1, the flame transfers from the combustion plate ignited by the pilot flame 21 in the direction of arrow A.

Since the fire transfer member 13 is fixed to the end presser member 7 by its engaging portion 17 and the engaging portion 12 of the recess 11, the fire transfer member 13 is always attached to the recess 12 of the end presser member 7. It will be located at. Since the end holding member 7 is provided with a recess 11 into which the seam holding plate 4 is fitted, the positioning of the holding member 7 with respect to the holding plate 4 in the recess 11 ensures that the fire transfer member 13 also fits into the seam holding plate 4. The flame transfer member 13 crosses over the combustion plates 2, 2 on both sides.
This allows for reliable positioning.
