Abstract
The utility model discloses a lower burner of a fuel gas oven. The lower burner of the fuel gas oven comprises a burning tube, a fire leading plate, an ignition needle and an ignition needle fixing frame, a plurality of burning holes are formed in the burning tube, the shape of the fire leading plate is matched with that of the burning tube, and the fire leading plate is tightly attached to the burning tube. The lower burner of the fuel gas oven can reduce the floating flame phenomenon and the flame extinction phenomenon, and reduce CO contained in exhaust gas.
Description
Technical field
The utility model relates to the gas burning roastor field, specifically relates to burner under a kind of gas burning roastor.
Background technology
Existing gas burning roastor is installed in the airtight cabinet, is in the untimely burning down of replenish air, and the longer flame of burner combustion pipe is not easy maintenance and can produces from flame, fray-out of flame phenomenon, and contained CO exceeds standard in the burnt gas.
The utility model content
(1) technical problem that will solve
At the deficiency that prior art exists, the utility model provides a kind of can be reduced from flame, fray-out of flame phenomenon, burner under the gas burning roastor of contained CO in the minimizing waste gas.
(2) technical scheme
For achieving the above object, the utility model provides burner under a kind of gas burning roastor, comprise combustion tube, the plate of igniting, igniting pin and igniting pin fixed mount, described combustion tube is provided with several burner ports and several vents, described vent places the below of described burner port, and the described plate of igniting is in the below of burner port.Described igniting pin fixed mount places one side of described combustion tube, and described igniting pin is installed on the described igniting pin fixed mount, and described igniting pin places on the burner port.
The combustion tube of burner is in the burner port design, the hypoxemia high pressure conditions requires in conjunction with liquefied gas and the natural gas various states minimizing fire hole areas that burn according to required thermic load, strengthen the flame intensity of single fire hole, improve fast the fire hole peripheral temperature, reach the air-flow of stablize combustion gas after the uniform temperature and prevent that the flame generation is from the flame phenomenon.
Further, also be provided with the ventilation adjusting ring on the described combustion tube, described ventilation adjusting ring places on the air inlet of described combustion tube.Reduce the area of vent under the hypoxemia high pressure conditions, because vent is in the plate the inside of igniting, vent forms steady fiery groove with the plate of igniting below burner port, the flame of steady fiery groove crosses conference and combustion flame throughput generation secondary interference replenish air is untimely, combustion flame insufficient CO that burns exceeds standard seriously, is that it can keep steady fire action not influence combustion flame again at steady flame that fire tank produces so only control the vent gas output well.
In the utility model, also cancelled the fireguard in the burner under the existing gas burning roastor in addition, cancelled fireguard generally at combustion tube, just made its single combustion tube heating, burnt gas just can be directly up, discharge by smokejack, can accelerate the baking box preheat temperature again, shorten stoving time.
Overall structure of the present utility model can be varied, and described combustion tube integral body is cylindric in the present embodiment.
Consider that at last combustion tube is longer, its air pressure inside there are differences, and described air inlet is in the two ends of described combustion tube, and dredge close centre, described burner port two ends.
(3) beneficial effect
Burner can reduce from flame, fray-out of flame phenomenon under the utility model gas burning roastor, reduces contained CO in the waste gas.

Fig. 2 is burner vertical view structural representation under the utility model gas burning roastor;
Fig. 3 is burner cutaway view structural representation under the utility model gas burning roastor;
Fig. 4 is the partial enlarged drawing of A part among Fig. 3.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Burner structure as shown in Figure 1, Figure 2, Figure 3 and Figure 4 under a kind of gas burning roastor of the present utility model; Under the described gas burning roastor burner comprise combustion tube 1, the plate 2 of igniting, igniting pin and igniting pin fixed mount 7, described combustion tube is provided with several burner port 4 and several vents 3, described vent 3 places the below of described burner port 4, and the described plate 2 of igniting is in the below of burner port 4.Described igniting pin fixed mount 7 places one side of described combustion tube 1, and described igniting pin is installed on the described igniting pin fixed mount 7, and described igniting pin places on the burner port 4.
The combustion tube 1 of burner is in burner port 4 designs, the hypoxemia high pressure conditions requires in conjunction with liquefied gas and natural gas various states minimizing burner port 4 gross areas that burn according to required thermic load, strengthen the flame intensity of single burner port 4, improve fast the fire hole peripheral temperature, reach the air-flow of stablize combustion gas after the uniform temperature and prevent that the flame generation is from the flame phenomenon.
Further, also be provided with ventilation adjusting ring 5 on the described combustion tube 1, described ventilation adjusting ring 5 places on the air inlet of described combustion tube 1.Reduce the area of the air inlet of combustion tube like this under the hypoxemia high pressure conditions, thereby reduce the insufficient generation CO of combustion flame burning.
In the utility model, also cancelled the fireguard in the burner under the existing gas burning roastor in addition, cancelled fireguard generally at burner, just made its single combustion tube 1 heating, burnt gas just can be directly up, discharge by smokejack, can accelerate the baking box preheat temperature again, shorten stoving time.
Overall structure of the present utility model can be varied, and described combustion tube 1 integral body is cylindric in the present embodiment.
Consider that at last combustion tube 1 is longer, its air pressure inside there are differences, and described air inlet is in the two ends of described combustion tube 1, and dredge close centre, described burner port 4 two ends.
The beneficial effects of the utility model: can reduce from flame, fray-out of flame phenomenon, reduce contained CO in the waste gas.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
