The inner flame hole 510 and the outer flame hole 520, and the inner flame hole 510 and the outer flame hole 520 are respectively connected to the inner and outer ring mixing chambers 500, 501; and between the inner and outer ring mixing chambers 500 A penetrating ring region 508 is formed at an appropriate distance for air outside the body 50 to pass from outside the outer ring mixing chamber 502 and through the penetrating ring region 508 The square begins to flow upward to the outer flame hole 520 of the outer ring furnace cover 52 and the inner flame hole 510 of the inner ring furnace cover 51, and serves as an oxygen supply amount required for combustion.

Although the above-mentioned creations can achieve the original purpose of creation, they are highly praised by the industry and the general operators. However, in view of the industry's continuous innovation and breakthrough in research and development and technology, the applicants have made more efforts to study. Improvement, and make it perfect and practical; plus, the creator has responded with numerous updates to the experimental test and the actual use of the consumer, and found that the following problems still need to be further improved:

1. In order to achieve the purpose of complete combustion, the distance between the area of the penetrating ring that has been located between the inner and outer ring mixing chambers is increased to increase the amount of gas supplied to the secondary gas, and For the purpose of penetrating the distance or area of the ring zone, the operator usually maximizes the size of the outer ring and minimizes the size of the inner ring to greatly increase the area of the penetrating ring zone. The purpose of combustion of the gas is completely mixed, so that not only will the volume of the burner be enlarged, but the material cost will be greatly increased to reduce its competitiveness, and at the same time, the inner ring will be burned. The area is minimized, and the heat of combustion is greatly reduced, which in turn requires a long heating time.

2. Since the conventional burner is composed of the cover of the furnace cover, and in order to overcome the cost problem of the first point, the manufacturer usually uses the cover and the body as different materials (that is, the cover is made of copper and the body is made of aluminum). Material, but the coefficient of thermal expansion and cold shrinkage of the two are different) to achieve the purpose of reducing costs, but, when long-term The effect of using cum, thermal expansion and contraction, and the wear and tear after disassembly, cleaning, and assembly, often result in gaps in the cover position of the furnace cover and the body, so that the gas contained in the inner and outer ring mixing chambers is formed. It will easily leak out from the gap between the lid and the cover of the body, so that it will cause endocytosis or gas explosion, which will greatly shorten its service life.

In view of this, the present invention proposes a single-ring double-tube type burner structure to effectively overcome the above problems in order to benefit all consumers and manufacturers in view of the above-mentioned shortcomings of the prior art.

The single-ring double-tube type burner head structure of the present invention is formed by a partition ring disposed inside the single-ring body to form two independent non-communicating inner and outer ring mixing chambers, so that the inner and outer ring mixing chambers are The inner ring and the outer ring mixing tube are respectively connected to each other, and the hollow body of the single ring body is provided with a hollow penetrating axial center region, and the single ring body is provided with an inner ring inclined surface and an outer ring inclined surface. And an inner annular hole and an outer flame hole respectively connected to the inner and outer ring mixing chambers respectively at the inner ring inclined surface and the outer ring inclined surface, so that the inner flame hole and the outer flame hole are ejected in different directions Mixed combustion, in this way, it can not only overcome the problem of air explosion which is easy to cause deflation or endocytosis at the combined position of the separate burner head and the furnace cover, and shorten the service life thereof, and at the same time, under the burner of the same size , the air supply area of the axial center zone and the combustion area of the inner ring can be maximized, and the combustion heat value and the time required for heating are greatly increased; in addition, the creation utilizes the single ring body. The inner and outer flame holes at the inner and outer ring slopes are oriented Eruption in the same direction, to increase the gap between two adjacent flame, and contribute to secondary Air can flow into the inner flame hole from the gap path formed between the two adjacent flames and the inner bottom side of the air supply area formed by the axial center to serve as the gas gas ejected from the inner flame hole The amount of oxygen required for the second complete mixing is such that it has complete combustion and reduces the generation of exhaust gas, thereby achieving the progressive effect of improving thermal efficiency and energy saving and carbon reduction.
