In addition, the visual gas distribution pipe 5 can directionally output pure gas, so that the pure gas conveyed by the visual gas distributor 7 can be burnt insufficiently in the windshield 8, thereby forming bright yellow flame, and the formed gas combustion can be observed manually. Thereby realizing the visualization.

Preferably, the output end of the wind resistant gas branched pipe 4 communicates with the wind resistant mixing pipe 6 in such a manner that the gas outputted therefrom can be mixed. The wind-resistant mixing pipe 6 can mix the received fuel gas with the injection air, so that the mixed gas mixed by the fuel gas and the oxygen is conveyed into the fireproof cover 8 positioned at the downstream of the pipeline, the mixed gas can be more easily ignited by the ignition device in the fireproof cover 8, the combustibility of the mixed gas is improved, the ignition success rate and the combustion strength of the mixed gas are improved, the influence of external wind on the blowing of the ignited flame can be resisted, and the ignition burner or the pilot burner with the structure can still maintain a relatively stable combustion state under the severe external conditions.

Preferably, the two visual gas branched pipes 5 are arranged at two sides of the wind-resistant gas branched pipe 4 in a mode that the pipe body axis of the visual gas branched pipe is parallel to the pipe body axis of the wind-resistant gas branched pipe 4, and the wind-resistant gas branched pipe 4 and the two visual gas branched pipes 5 reduce the independence of different branched pipes while keeping the safety distance between the two visual gas branched pipes, so that the gas distributor 3 is communicated with the wind-resistant gas branched pipe 4 and the two visual gas branched pipes 5 in a mode that the received gas is branched into three paths of gas. The gas distributor 3 can divide the gas into three different gas flows, so that the gas flow in the wind-resistant gas branch pipe 4 is larger than that in the visual gas branch pipe 5, and the combustion stability is ensured.

Preferably, the output end of the wind-resistant mixing tube 6 is communicated with the inner space of the windshield 8, so that the fuel gas mixed therein can be ignited in the windshield 8, combustion of the fuel gas in a specified environment is realized, the outside wind can be resisted by the windshield 8, and the flame can be kept in a relatively stable state. As shown in fig. 2, the wind resistant mixing pipe 6 includes at least a shrink tube 61, a mixing tube 62, a diffuser 63, a rectifier 64, a gas nozzle 65, and a damper disc 66. Preferably, the air-resistant mixing pipe 6 communicates the gas nozzle 65, the shrinkage pipe 61, the mixing pipe 62 and the diffusion pipe 63 in this order in such a manner as to form an ejector structure capable of mixing the gas with the ejector air. Specifically, the gas nozzle 65 is partially inserted into the shrink tube 61 in such a manner that an air intake is formed between it and the shrink tube 61, and an end of the gas nozzle 65 remote from the shrink tube 61 communicates with an output end of the wind resistant gas branched tube 4. The diffuser 63 communicates with the inner space of the windshield 8 through a flow regulator 64 that adjusts the flow rate of the mixed fuel gas. When the burner works, the output gas from the wind-resistant gas branch pipe 4 is accelerated through the gas nozzle 65, air is injected into the shrinkage pipe 61, the gas injected from the gas nozzle 65 and the injected air are fully mixed in the mixer 62, and secondary mixing is carried out after the gas passes through the diffuser 6.3, so that the mixing treatment of the gas is realized.

Preferably, the output end of the visual gas branch pipe 5 is communicated with the visual gas distributor 7. The visual gas distributor 7 can secondarily distribute the gas for visual combustion. The secondary distribution of partial fuel gas for visual combustion is to make the visual flame formed by multiple visual fuel gases have approximately equal states, so that the results of manual observation from different angles of the burner can be approximately the same, and the occurrence probability of observation errors is reduced.

As shown in fig. 3, the visual gas distributor 7 comprises an annular bladder 71 and a nozzle 72. The annular air bag 71 is sleeved on the wind-resistant mixing pipe 6. The same annular air bag 71 is communicated with at least two visual fuel gas branch pipes 5; so that the plurality of visual gas branch pipes 5 connected in parallel with the wind-resistant gas branch pipe 4 can synchronously convey the gas for visual combustion conveyed by the visual gas branch pipes into the annular air bag 71. Preferably, the output end of the visualisation gas manifold 5 communicates with an annular surface of the annular balloon 71 close to the anti-wind gas manifold 4 and parallel to the axial cross section of the anti-wind mixing tube 6. It is further preferred that two nozzles 72 are connected to the annular face of the annular airbag 71 remote from the visual gas manifold 5 such that the annular face of the visual gas manifold 5 and the annular face of the nozzles 72 are parallel to each other. Preferably, the two nozzles 72 are symmetrically arranged on the annular surface in such a way that the amount of gas they acquire is equal. It is further preferred that the axis of the visual gas manifold 5 coincides with the extension of the axis of the nozzle 72. Preferably, the output end of the nozzle 72 is also in communication with the interior space of the windshield 8, so that the combustion of the gas injected by the nozzle 72 can take place inside the windshield 8. When the burner works, the gas output by the visual gas branch pipe 5 enters the annular air bag 71, and then the gas directly enters the windshield 9 from the nozzle 72 at the upper part of the annular air bag 71. The arrangement of the nozzles 72 provides a wider diffusion/distribution area for the exiting clean fuel gas so that it is more readily ignited by the burning mixture. In addition, since the fuel gas for visual combustion ejected from the nozzle 72 is pure fuel gas, insufficient combustion occurs after the pure fuel gas enters the windshield 8, so that the flame generated by the fuel gas output by the nozzle 72 during combustion is long and red, visual discrimination of the burner during combustion is increased, and the combustion state of the burner can be observed through naked eyes or camera videos even under the conditions of strong sunlight and good light. Preferably, the visualization means that the remote manual observation is visible, and especially when the sunshine pipeline is good, the flame of the burner can be observed by the manual naked eyes or video camera shooting.

Preferably, a plurality of ventilation holes 81 are provided on the side surface of the windshield 8 at intervals. So that air can enter the inner space of the draft shield 8 to provide oxygen for combustion of the gas. Preferably, the top of the inner cavity of the windshield 8 is provided with a flame stabilizing unit 9. Specifically, the end of the flame holding unit 9 is connected to the side surface of the windshield 8 near the edge position of the top surface so that the flame holding unit 9 can extend inward from the side wall of the windshield 8. Preferably, a plurality of flame stabilizing units 9 are arranged at spaced intervals within the windshield 8. Further preferably, the flame stabilizing unit 9 may be an S-shaped flame stabilizing block. The S-shaped flame stabilizing block can shield the part area of the top port of the windshield 8, and the area of the port is reduced so that the flame can be sprayed out from a smaller caliber only. Especially, the S-shaped flame stabilizing block can shield and guide visual fuel gas/flame close to the edge of the inner wall of the windshield 8, so that the S-shaped flame stabilizing block can be better fused with the mixed combustion flame close to the axis area of the windshield 8, the size of the flame ignited by the visual fuel gas is enhanced, and the combustion stability is improved.
