Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a full secondary combustion type and a burner.

Conventional structure and its problems Some burners used in conventional gas appliances have a head made of aluminum die-casting and a rectifying plate and a flame hole ring placed on top of it, but aluminum die-casting has a complicated shape. If this happens, mass productivity will be greatly reduced, leading to a significant increase in costs.

Purpose of the invention The object of the present invention is to provide a gas supply section of a fully secondary combustion type gas burner with a structure that can be easily machined and to be able to supply gas uniformly.

Structure of the invention This invention provides a red-hot cylinder made of a punched wire mesh plate, a lath net, etc. on the outside of an inner flame cylinder having a plurality of small holes, and a cylinder made of a heat-resistant, heat-permeable material. The gas supply section for supplying gasified fuel to the combustor has a simple shape, and the gasified fuel is uniformly supplied to the two combustion gain bodies.

Description of examples An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows the overall configuration.

The gas 1 enters the gas supply section 3 from the joint 2, and the gas, which is made uniform in the circumferential direction, passes between the outer flame tube 4 and the inner flame tube 5 and heads upward.

The gas mixes with air 9 taken in through the small holes at the bottom of the outer flame tube 4 and the inner flame tube 5, forms a flame 10, and makes the lath net 6 red hot.

Air is also introduced into the flame from the upper part of the inner flame tube 5 and the lath net 6 to achieve complete combustion.

The lath screen is surrounded by heat-resistant glass 7 and has a shape that allows stable red heat to be obtained while avoiding external influences.

As shown in FIG. 2, the gas supply section 3 includes a flame ring 3c having a gas outlet 6 and a rectifier ring 3b for making the gas uniform.
and a body 3a, which are integrated by caulking.

The joint 2 is threaded and sealed by a gas pipe 14 and a cap nut 13.

The joint 2 is fixed to the body 3a by caulking or spot welding and gas-sealed.

The gas that has entered the body 3a is uniformly supplied to the entire circumference by the rectifier ring 3b, and the rectifier ring hole 16 is connected to the gas outlet 1.
5 and prevents gas from rising directly above.

Here, the diameter of the gas jet port 15 and the rectifying ring hole 16 is φD.
There is a relationship of 〉φd.

Only that part of the rectifier ring hole 16 located directly above the joint 2 is blinded, which prevents a large amount of high-pressure gas from the joint 2 from spewing out from this part, and allows gas to be uniformly supplied to the entire circumference, thereby improving combustion. The entire device is designed to perform at its best.

Effects of the invention As described above, the present invention provides a gas supply section for a fully secondary combustion burner that is pressed into a simple shape and can be easily gas-sealed by caulking or spot welding the joint. It is.

Furthermore, by closing the rectifying ring hole directly above the joint, gas can be uniformly supplied to the entire circumference, resulting in even combustion.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) An upper mold which is provided with an inner flame cylinder and an outer flame cylinder, and which is press-acid molded and has a protrusion forming a plurality of gasified fuel injection holes; A complete secondary system having a gas supply section comprising a lower mold which is attached to the mold and press-formed, and a rectifier plate which is shifted in position from the gasified fuel jet nozzle is sandwiched between the upper mold and the lower mold. Combustion type (2) The full secondary combustion type burner according to claim 1 of the utility model registration claim, which has a button on the gas supply section and a joint for connecting the pipe of the gasified fuel passage fixed to the lower mold. (3) The full secondary combustion type burner according to claim 1, which is a registered utility model, wherein an opening is provided in the rectifier plate at a portion of the gas supply section that does not face the joint.
