Double-fire-hole characteristic combustor formed by vertically stacking thin pipe annular row sets

Abstract

The invention relates to the field of commercial kitchenware, in particular to a double-fire-hole characteristic combustor formed by vertically stacking thin pipe annular row sets. Thin pipes 2 are uniformly distributed on the surface of one surface of an annular partition plate 4 by a circle; the outlet of the thin pipes 3 faces a combustion chamber 5-1; the inlet of the thin pipes 3 faces a firedistribution chamber 1-1; a plurality of annular partition plates 4 on which the thin pipes 3 are distributed are stacked together to form a distributor 3-1 of the combustor; holes with the cross sections similar to triangles formed between the outer walls of every two adjacent thin pipes 3 and the surface of the annular partition plate 4 are auxiliary fire holes 3-1-2. The auxiliary fire holes 3-1-2, the inner holes of the thin pipes 3 and the main fire holes 3-1-1 jointly form double characteristic fire holes of the fire distributor 3-1, wherein the combustion chamber 5-1 is arranged in thecenter area of the fire distributor 3-1, a distribution chamber gland 2 is arranged on the fire distributor 3-1, a distribution chamber outer barrel 1 is connected to the lower part of the outermostperiphery of the distribution chamber gland 2. The gas combustor which is identical in size of fire hole diameter and excellent in combustion performance can be provided.

[0002] The premixed gas burner with a cylindrical combustion chamber with horizontal fire holes is a kind of gas burner widely used in the kitchen industry at present. The flame distributor of this type of gas burner is cylindrical, and the fire hole is set in the cylinder In the wall, the axes of the fire holes all face the center of the cylinder, and the opening ends of the fire holes are flush with the inner wall of the cylinder. The straight cylinder is the most common, and the vertical direction of the fire hole opening is completely hidden in the cylinder wall. Water or other substances falling vertically from above will not directly fall into the fire hole, so it is not easy to block the fire hole channel. Since the axis of the fire hole is all facing the center of the combustion chamber, the premixed gas flows laterally to the interior of the combustion chamber. Then change the trajectory to flow out vertically, the curved flow trajectory of the premixed gas increases the residence time of gas and heat inside the combustion chamber, which is conducive to the concentrated combustion of the mixed gas and can effectively increase the temperature rise inside the combustion chamber, so most of them have better However, the flame holes of this type of gas burner are almost all processed by mechanical cutting. Cutting not only produces a lot of waste materials, but also consumes a lot of production and processing time, which will inevitably push up the product. Production and processing costs; due to the singleness of the flame holes formed by mechanical processing, it is difficult to make the hole spacing small and uniform due to the limitation of processing conditions and the strength of the substrate used, and it is also difficult to make the hole spacing small and even on a gas burner. , Production and processing of fire holes with dense distribution, a large number and different shapes, it is difficult to make the porosity of the fire holes on the combustion tube very high, and the total cross-sectional area of ​​the fire holes is enlarged, so the flow rate of the premixed gas flowing out through the fire holes The flow rate is single, and the flow rate is high, the disturbance between the air streams is large, and the combustion reaction noise is large, so a new type of gas burner burner is designed
