Abstract

Disclosed is a firing ring for a gas-fired combustor. A firing surface with a shape of concave arc or concave spherical is arranged between an inner ring and an outer ring. One circle or a plurality of circles of firing holes are evenly distributed on the firing surface. The firing holes are circular or strip-slot shaped. The strip-slot shaped firing holes can be a group of strip slots arranged along the spoke line or a group of spiral strip slots which form a skew angel with the spoke line. The utility model has low pollution discharge and excellent combustion performance with high heat efficiency.

Description

Burner for gas stove is got angry and is enclosed

(1) technical field:

The utility model is a kind of burner for gas stove ignition circle.

(2) background technology:

The burner for gas stove ignition circle of prior art is in the majority with the form on planar shaped and planar band inclined-plane, novel embedded kitchen range development is adopted convex to get angry and is enclosed, on convex globoidal upper outside circumference, be distributed with some circular holes of getting angry, also there are all gap-shapeds that distribute in the outside of convex globoidal to get angry the hole, as ZL00219928.9, the shortcoming that exists is that pollutant is higher in the combustion product gases, firepower disperses, pot center firepower deficiency, and is bigger than normal to the heat loss of the diffusion of radiation all around simultaneously.

(3) summary of the invention:

The purpose of this utility model is for overcoming above-mentioned shortcoming, study, test, be designed to a kind of novelty, practical combustibility be improved significantly burner get angry circle.

Scheme of the present utility model is: burner ignition circle has ignition face [1], ignition hole [2], outer ring [3], shirt rim [4] and inner ring [6], ignition face [1] between outer ring [3] and inner ring [6] be shaped as annular cancave cambered surface or annular concave spherical surface, get angry hole [2] at being evenly distributed on the ignition face [1] of cancave cambered surface ringwise or annular concave spherical surface shape.

Improvement project is that ignition hole [2] is circular fire hole or gap-shaped fire hole, ignition hole [2] on the ignition face [1] can be made into one and encloses or a few, gap-shaped fire hole ignition hole [2] can be made for the bar seam that one group of spoke line direction is arranged, also can be made into one group of screw bar seam that becomes skew angle with the spoke line, also can go up fire hole is designed to the mixed form that one group of gap-shaped fire hole adds the circular fire hole of a circle at ignition face [1].

The utility model is simple, practical, combustibility is preferably arranged, can limit the generation that auxiliary air enters the root inhibition NOx of flame, can control auxiliary air again in right amount and make the CO stable content on low-level, reduce the horizontal direction radiant heat diffusion of thermal-flame simultaneously, the thermal-collecting energy-saving effect is arranged.

[5] male half coupling [6] inner ring

(5) specific embodiment:

Accompanying drawing 1 discloses structure of the present utility model, be and be distributed with the circular holes [2] of getting angry of 2 circles on the ignition face [1] of cancave cambered surface shape, the outer outer ring [3] that is with of ignition face [1], there is male half coupling [5] its lower edge, be connected to shirt rim [4] under the outer ring [3], at ignition face [1] center circular hole is arranged, the circular hole wall forms the inner ring [6] of annular, inserts endoporus when inner ring [6] and male half coupling [5] are used to pack into burner body and makes axial location usefulness.

Fig. 2 gets angry for the screw bar-slot fire-hole and encloses the embodiment outside drawing, go up uniform 40 bar-slot fire-holes [2] at concave spherical surface shape ignition face [1] and all one angle is arranged with spoke line oblique, curl, stretch under ignition face [1] the center circle hole wall and partly be inner ring [6], the outer shirt rim [4] that is with of outer ring [3], shirt rim [4] dimension face in the form of a ring are used to stop that soup splashes into the outer narrow slit of burner body, have decorative function again, can integral body make, be inserted in after also detachment is made.

Claims

1, a kind of burner for gas stove is got angry and is enclosed, ignition face [1], ignition hole [2], outer ring [3], shirt rim [4], inner ring [6] are arranged, what it is characterized in that being positioned at ignition face [1] between outer ring [3] and the inner ring [6] is shaped as annular cancave cambered surface or annular concave spherical surface, gets angry hole [2] at being distributed on the ignition face [1] of cancave cambered surface ringwise or annular concave spherical surface shape.

2, burner for gas stove according to claim 1 is got angry circle, it is characterized in that described ignition hole [2] is evenly distributed on the ignition face [1] of cancave cambered surface ringwise or annular concave spherical surface shape, becomes a circle or a few, and getting angry the hole is circular fire hole or gap-shaped fire hole.

3, burner for gas stove according to claim 2 is got angry circle, it is characterized in that it is the bar seam that one group of spoke line direction is arranged that described gap-shaped fire hole is got angry hole [2], also one group become the screw bar of skew angle to stitch with the spoke line.
