Abstract

The utility model discloses a fuel gas combustor which comprises a combustion head base. A combustion head is installed in the cavity of the combustion head base. Air holes are densely distributed onthe combustion head. A stove ring is fixedly installed on the combustion head base. The combustion head base is in a hollow structure which comprises an internal wall and an external wall. The hollowspace between the internal wall and the external wall is an air inlet tunnel. A fuel gas inlet which supplies the fuel gas for the combustion head is arranged on the internal wall. An air inlet whichis connected with the air inlet tunnel is arranged on the external wall. An air inlet hole which is communicated with the air inlet tunnel is arranged on the internal wall. The stove ring is a hollowstructure which comprises an internal ring wall and an external ring wall. The hollow space between the internal ring wall and the external ring wall is an air return tunnel. An air return hole is arranged at the upper part of the internal ring wall. An air draft hole is arranged at the lower part of the external ring wall. The air return hole and the air draft hole are communicated with the air return tunnel. The fuel gas combustor has the advantages of full fuel gas combustion and high heat efficiency.

Description

Gas burner

Technical field

The utility model relates to a kind of burner that is used to fry on the stove.

Background technology

The existing gas burner that is used to fry on the stove comprises that inner chamber is equipped with the burning headstock of combustion head, and burning is fixed with the stove circle on the headstock, by the air blast forced air supply to reach the purpose of hyperactivity of fire.The gas burner of said structure, the combustion gas atomizing effect is poor, and it is insufficient to burn, and the part combustion gas flows away with thermal-flame, contaminated environment not only, but also cause the combustion gas waste.In addition, when combustion gas flowed away, a part of heat also flowed away thereupon, caused the thermal efficiency lower thus.

The utility model content

The technical problems to be solved in the utility model is at above-mentioned deficiency, provides a kind of fuel gas buring abundant, the gas burner that the thermal efficiency is high.

In order to solve the problems of the technologies described above, the utility model provides a kind of gas burner of following structure, comprise that inner chamber is equipped with the burning headstock of combustion head, be fixed with the stove circle on the burning headstock, its design feature is: be densely covered with air-vent on the described combustion head, the folder hollow structure of burning headstock for constituting by inner and outer wall, folder dead zone between the inner and outer wall is an air intake passage, inwall is provided with to the fuel gas inlet of combustion head for combustion gas, outer wall is provided with the air inlet that is communicated with air intake passage, and inwall is provided with the fresh air inlet that is communicated with air intake passage; The folder hollow structure of described stove circle for constituting by inner ring wall and collar wall, the folder dead zone between inner ring wall and the collar wall is for returning the wind passage, and inner ring wall top is provided with returns the wind hole, and the collar wall bottom is provided with vent, returns wind hole and vent and returns the wind channel connection.

The gas burner of said structure, the bottom shape of employed frying pan will match with the opening of stove circle, its combustion process is as follows: combustion gas is flowed out by the combustion gas discharge port on the combustion head, air blast is sent air with combustion gas to through air intake passage and fresh air inlet and is fully mixed, combustion gas is better atomized, fully mix with air and the combustion gas that atomizes just can be fully burned in the combustion chamber that the stove circle is surrounded; In addition, on the long flare of scurrying and the mist of high temperature, under the stopping of frying pan, enter and return the wind passage by returning the wind hole, unburnt small part combustion gas is further burnt in returning the wind passage, the heat that burning produces and the mist of high temperature with heat return combustion chamber by the inner ring wall, make combustion chamber remain on the condition of high temperature, waste gas after burning is discharged by vent.

Be not difficult to draw by foregoing description, it is abundant to the utlity model has fuel gas buring, the advantage that the thermal efficiency is high.

In order to make air and combustion gas mixing even, the surface tilt setting of the center line opposed inner walls of described fresh air inlet.

More even for air and combustion gas mixing are got, described fresh air inlet is periphery on inwall, is divided into three circles from top to bottom along inwall.Above a circle fresh air inlet incline direction unanimity in the horizontal direction, below the incline direction unanimities of two circle fresh air inlet in the vertical directions.

For convenience light combustion gas at any time, be connected with the naked light pipe on the described burning headstock.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cutaway view along A-A line among Fig. 1.

The specific embodiment

Gas burner as depicted in figs. 1 and 2, comprise that inner chamber is equipped with the burning headstock 1 of combustion head 2, be fixed with stove circle 3 on the burning headstock 1, be densely covered with air-vent 14 on the above-mentioned combustion head 2, burning headstock 1 is the folder hollow structure that is made of inwall 11 and outer wall 12, folder dead zone between inwall 11 and the outer wall 12 is an air intake passage 4, the bottom of inwall 11 is provided with to the fuel gas inlet 5 of combustion head 2 for combustion gas, the bottom of outer wall 12 is provided with the air inlet 6 that is communicated with air intake passage 4, inwall 11 is provided with the fresh air inlet 7 that is communicated with air intake passage 4, fresh air inlet 7 is periphery on inwall 11, be divided into three circles from top to bottom along inwall, the surface tilt setting of the center line opposed inner walls 11 of fresh air inlet 7, above circle fresh air inlet 7 an incline direction unanimity in the horizontal direction, below the incline direction of two circle fresh air inlets 7 in the vertical directions consistent and be inclined upwardly, the quantity of each circle fresh air inlet 7 is a plurality of, can decide according to the diameter and the instructions for use of burning headstock 1, the above-mentioned fresh air inlet that is obliquely installed 7 can make air form eddy flow, reach the purpose of better and combustion gas mixing, can improve the combustion rate of combustion gas.The folder hollow structure of above-mentioned stove circle 3 for constituting by inner ring wall 31 and collar wall 32, stove circle 3 is inverted cone shape, the upper end of stove circle 3 is the opening that matches with the frying pan shape, the inner chamber that inner ring wall 31 surrounds is a combustion chamber 13, folder dead zone between inner ring wall 31 and the collar wall 32 is for returning wind passage 8, inner ring wall 31 top loop are provided with a plurality of wind holes 9 of returning, returning the quantity in wind hole 9 can decide according to the diameter and the instructions for use of stove circle 3, collar wall 32 bottoms are provided with vent 10, return wind hole 9 and vent 10 and return wind passage 8 and be communicated with.The quantity of vent 10 is a plurality of, can decide according to the diameter and the instructions for use of stove circle 3.Be connected with the naked light pipe 15 that is communicated with combustion gas on the burning headstock 1.
