The embodiment of the utility model provides a burner structure, as shown in fig. 1-4, comprising a burner body 100, an air inlet seat 200 and a nozzle assembly 300, wherein an outer ring cavity 111 and an inner ring cavity 121 are arranged in the burner body 100, and the outer ring cavity 111 and the inner ring cavity 121 are used for mixing fuel gas and air. The top of the burner body 100 is provided with an outer ring outlet 113 communicated with the outer ring cavity 111 and an inner ring outlet 123 communicated with the inner ring cavity 121, and mixed gas flows out from the outer ring outlet 113 and the inner ring outlet 123, and after passing through the distributor, the mixed gas is ignited to form outer ring flame and inner ring flame. The air inlet seat 200 is fixed on one side of the burner body 100, and specifically, the air inlet seat 200 may be integrally connected with the burner body 100. The top surface of the intake seat 200 is provided with an intake groove 210 that is concave. The nozzle assembly 300 may be disposed at one side of the intake seat 200, and the nozzle assembly 300 includes an outer ring nozzle 310 and an inner ring nozzle 320. An outer ring air inlet channel 112 communicated with the outer ring cavity 111 and an inner ring air inlet channel 122 communicated with the inner ring cavity 121 are arranged on one side wall of the air inlet groove 210, and the outer ring air inlet channel 112 and the inner ring air inlet channel 122 can penetrate through the air inlet seat 200 and are communicated with the corresponding cavities. The other side wall opposite to the intake groove 210 (i.e., the other side wall opposite to the side wall provided with the outer ring intake passage 112 and the inner ring intake passage 122) is provided with a plurality of perforations 211 respectively abutting against the outer ring intake passage 112 and the inner ring intake passage 122, i.e., a part of the perforations 211 abuts against the outer ring intake passage 112 and the other part of the perforations 211 abuts against the inner ring intake passage 122, specifically, the perforations 211 may be coaxially provided with the corresponding outer ring intake passage 112 or inner ring intake passage 122. The outer ring nozzle 310 and the inner ring nozzle 320 are disposed at the perforations 211 and are disposed toward the outer ring intake passage 112 and the inner ring intake passage 122, respectively, so that the outer ring nozzle 310 can inject fuel gas toward the outer ring intake passage 112 and the inner ring nozzle 320 can inject fuel gas toward the inner ring intake passage 122. Compared with the traditional structure, the distance from the nozzle to the air inlet channel can be increased, air firstly enters the air inlet groove 210 at the top of the air inlet seat 200, then enters the corresponding air inlet channel along with the fuel gas, and finally enters the gas mixing cavity to be mixed with the fuel gas. Therefore, the embodiment can increase the air inflow of air, improve the ratio of fuel gas to air and improve the combustion effect.
In some embodiments, the outer ring air intake passage 112 is provided with two and is respectively located at two sides of the inner ring air intake passage 122, the outer ring nozzle 310 is provided with two and is respectively located at two sides of the inner ring nozzle 320, and the sidewall of the air intake groove 210 is provided with three perforations 211. Since the volume of the outer ring cavity 111 is relatively larger than that of the inner ring cavity 121, the number of the outer ring air inlet channels 112 is increased in this embodiment, so that the air amount entering the outer ring cavity 112 can be increased, the ratio of fuel gas to air is further improved, and the combustion effect is improved.
Further, the side wall of the outer ring cavity 111, which is far away from the outer ring air inlet channel 112, is provided with the baffle 130, when the fuel gas and the air enter the outer ring cavity 111 along the outer ring air inlet channel 112, the baffle 130 can play a certain role in blocking the air flow, so that a part of mixed gas flows back in the outer ring cavity 111, and thus, the mixing of the fuel gas and the air can be enhanced, the mixing of the fuel gas and the air is more uniform, and the combustion effect is further improved.
Furthermore, the extending directions of the two outer ring air inlet channels 112 are parallel to the baffle 130, and the two outer ring air inlet channels 112 are symmetrically distributed relative to the baffle 130, and the baffle 130 is positioned at the center line of the two outer ring air inlet channels 112, so that the baffle 130 has the same flow guiding effect on the air flow blown from the two outer ring air inlet channels 112, and the mixing of the fuel gas and the air in the outer ring cavity 111 can be more uniform.
In some embodiments, the burner body 100 includes a burner top cover 101 and a closure plate 102, an opening is provided at the bottom of the burner top cover 101, the closure plate 102 is fixed at the bottom of the burner top cover 101 and seals the opening, and the burner top cover 101 and the closure plate 102 enclose an outer ring cavity 111. The outer ring cavity 111 can be opened by the split structure, so that the injection guide plate 130 or other components can be conveniently assembled inside the outer ring cavity 111. The bottom of the furnace top cover 101 can be provided with a plurality of guide posts, the blocking plate 102 is provided with positioning holes matched with the guide posts, and the guide posts can be inserted into the positioning holes to position the blocking plate 102.
In some embodiments, the distance from the outer ring nozzle 310 to the outer ring intake passage 112 is less than the distance from the inner ring nozzle 320 to the inner ring intake passage 122, which may further increase the amount of air entering the inner ring intake passage 122, enhancing the combustion effect of the inner ring flame.
In some embodiments, ignition pins 140 are secured to burner body 100 for igniting the fuel gas.
In some embodiments, the burner body 100 is further fixed with a thermocouple 150, and the thermocouple 150 can detect the temperature of flame to play a role of flameout protection.
