Abstract

The utility model discloses a burner and aims at providing a burner with a simple structure and a more complete and stable burning. The burner takes advantage of a circumferential seam which communicates with a fuel gas access of the flames of an inner circle to scheme out booster flames at the circumference of the flames of an inner circle, and continuously light and implement the flames of the inner circle when transferring the flames from outer cycle flame holes to the inner cycle flame holes, thereby making the burning more complete and stable. The utility model is composed of a chassis, a jet exhauster, an outer cycle flame reducer provided with the outer cycle flame holes, and an inner cycle flame reducer provided with the inner-ring flame holes; wherein, the circumference of the inner cycle flame holes is provided with the circumferential seam which communicates with fuel gas access of the flames of an inner circle through an access of mixed gas.

Description

Burner

Technical field

The utility model relates to a kind of burner of gas furnace, relates in particular to a kind of gas range burner of annular.

Background technology

At present, the essential structure of known gas stove burner is made up of gas inlet pipe, Internal and external cycle glory hole, vent, vent is several the independent apertures between the Internal and external cycle glory hole, effect is to transmit Internal and external cycle flame, though the vent that is interrupted can be connected Internal and external cycle flame, flame propagation velocity is limited, and still is difficult to reach clean-burning requirement, flame instability, be easy to generate tempering, from flame, take off rough burning phenomenons such as fire, Huang Yan.

Summary of the invention

The utility model has overcome the deficiencies in the prior art, provides a kind of simple in structure, the burner that sufficient combustion is stable.

A kind of burner that the utility model provides, comprise base 1, injector 5, offer outer ring glory hole 2 outer ring Huo Gai, offer the inner ring fire lid 4 of inner ring glory hole 3, described inner ring glory hole 3 peripheries are provided with circumferential gap 6, and are communicated with circumferential gap 6 by the fuel gas path of mist path 7 with inner ring flame.

Described circumferential gap 6 is located between inner ring fire lid 4 and the base 1, is the continuous circular shape space.

Advantage of the present utility model is, has set up annular continuous booster flame, makes flame propagation velocity obviously speed, and it is more abundant to burn, and CO content is very low, flame stabilization, be difficult for to produce tempering, from flame, take off the phenomenon of rough burnings such as fire, Huang Yan.

In addition, the utility model energy-saving and environmental protection, combustion noise is low, and the efficient height is safe and reliable, applied widely.

The specific embodiment

For clearer description the utility model, now reach specific embodiment in conjunction with the accompanying drawings and be described.

As shown in Figure 1, 2, this burner comprise base 1, injector 5, offer outer ring glory hole 2 outer ring Huo Gai, offer the inner ring fire lid 4 of inner ring glory hole 3.

As shown in Figure 2, inner ring fire lid 4 is up-small and down-big hollow ring cone, and inner ring glory hole 3 is evenly distributed on it, and the direction of each glory hole all keeps perpendicular to inner ring fire lid 4.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, be provided with circumferential gap 6 between inner ring fire lid 4 and the base 1, this circumferential gap 6 is positioned at inner ring glory hole 3 peripheries, and is parallel to inner ring glory hole 3.Booster flame mist path 7 is communicated with the fuel gas path and the circumferential gap 6 of inner ring flame, and the combustion mixture body is caused circumferential gap 6 by injector 5.When Chang Minghuo lighted this burner, outer ring flame passed to inner ring flame, because circumferential gap 6 is a continuous circular shape space, so booster flame 8 can all light in circumferential gap 6 in a flash, and simultaneously whole inner ring glory holes 3 all lighted.Because booster flame 8 burns in a circumferential gap, so the flame continuous burning, and naked eyes almost cannot see, and make this booster flame play the effect of rationally auxiliary inner ring master flame.In this process, passing the fire time mainly is to occur between the Internal and external cycle, in case reach inner ring, inner ring flame can all lighted in a flash.And 8 burnings of continuous booster flame are more abundant, and CO content is lower, and the breakpoint combustion replenishes inner ring flame, make that burning is more stable, are difficult for producing tempering, from flame, the phenomenon of taking off unstable burn incompletelys such as fire, Huang Yan.

Claims (3)

1, a kind of burner, comprise base (1), injector (5), offer outer ring glory hole (2) outer ring Huo Gai, offer the inner ring fire lid (4) of inner ring glory hole (3), it is characterized in that, inner ring glory hole (3) periphery is provided with circumferential gap (6), and is communicated with circumferential gap (6) by the fuel gas path of mist path (7) with inner ring flame.

2, burner according to claim 1 is characterized in that, described circumferential gap (6) is located between inner ring fire lid (4) and the base (1).

3, burner according to claim 1 is characterized in that, described circumferential gap (6) is the continuous circular shape space.
