DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] like Figure 1-5 As shown, as an embodiment of improving the combustion effect, the torch-type energy-saving and environmentally friendly burner of the present invention comprises a torch-shaped burner 1, wherein a first accelerating spraying furnace chamber 2 for forcing out the fire and diffusing the fire to the surroundings inside the torch-shaped burner 1 is provided in the torch-shaped burner 1, a furnace chamber air inlet 3 is provided at one end of the first accelerating spraying furnace chamber 2, and a first injection port 4 is provided at the other end of the first accelerating spraying furnace chamber 2 opposite to the furnace chamber air inlet 3, and the diameter of the furnace chamber air inlet 3 is smaller than the diameter of the first injection port 4;

[0028] By setting the diameter of the furnace cavity air inlet 3 to be smaller than the diameter of the first injection port 4, the air can be added more effectively to disperse the premixed airflow and the fire, and the fire can be fully diffused around the inside of the torch-shaped burner head, so as to achieve a more balanced combustion effect, and effectively avoid uneven firepower leading to insufficient gas combustion and excessive carbon dioxide production, which makes it difficult to achieve a medium-pressure fire combustion effect.

[0029] As an embodiment for improving the combustion effect, a second injection port 6 connected to the first injection port 4 is provided at one end of the second accelerating injection pressure furnace chamber 5, and an injection outlet 7 is provided at the other end of the second accelerating injection pressure furnace chamber 5 opposite to the second injection port 6, and the diameter of the second injection port 6 is larger than the diameter of the injection outlet 7;

[0030] By setting the structure that the diameter of the second injection port 6 is larger than that of the injection port 7, air is further added to disperse the gas so as to improve the combustion balance effect, effectively avoiding uneven fire power leading to insufficient gas combustion and excessive carbon dioxide production, which makes it difficult to achieve the combustion effect of medium-pressure fire power, and the effect of accelerated injection pressure combustion is achieved through the injection port in a closed shape.

[0031] As an embodiment for enhancing combustion acceleration and improving combustion effect, a plurality of deep holes 8 for combustion acceleration are also included, one end of the deep hole 8 is exposed to the outer end surface of the torch-shaped burner head 1, and the other end of the deep hole 8 is connected to the first accelerating injection furnace chamber 22. The deep holes 8 can also form a channel effect, effectively preventing the torch-shaped burner head 1 from forming a dangerous situation of closed-door flashback due to the premixed airflow with a relatively high pressure that may be generated in the case of incomplete combustion. The closed-door flashback is likely to cause dangers such as deflagration, so there is a great safety hazard.

[0032] In this embodiment, the deep holes 8 surround the outer circumference of the center of the outer end surface of the torch-shaped burner head 1 to form circularly distributed deep holes 8. The inner diameter of the deep holes 8 is 2.5 mm-4 mm, preferably 3 mm.

[0033] As an embodiment to further improve the combustion effect, the cross-section of the first accelerated spray pressure furnace chamber 2 is in the shape of a drum with a large upper port and a small lower port, and the furnace chamber air inlet 3 and the first injection port 4 are transitioned by a circular arc curve. The first accelerated spray pressure furnace chamber 2 has a drum-like structure with a large upper port and a small lower port, which can more effectively add wind to disperse the premixed airflow and disperse the firepower, and fully diffuse the firepower to the surroundings of the torch-shaped burner head 1, so as to achieve a more balanced combustion effect, effectively avoid incomplete combustion of gas and excessive carbon dioxide production due to uneven firepower, and thus make it difficult to achieve the combustion effect of medium-pressure firepower. The setting of the circular arc curve transition can be more conducive to the full diffusion of the premixed airflow.

[0034] As an embodiment to further improve the combustion effect, the cross-section of the second accelerating spray pressure furnace chamber 5 is a truncated cone with a small upper port and a large lower port, and the diameter of the lower port of the second accelerating spray pressure furnace chamber 5 is smaller than the diameter of the first injection port, so that a step-like structure is formed between the lower end of the second accelerating spray pressure furnace chamber 5 and the first injection port 4 for the deep hole 8 to pass through.

[0035] The second accelerated pressure-injection furnace chamber 5 is arranged with a small upper end and a large lower end, and further adds wind to disperse the gas to improve the effect of balanced combustion, effectively avoiding uneven firepower leading to insufficient combustion of gas and excessive production of carbon dioxide, which makes it difficult to achieve the combustion effect of medium-pressure firepower, and achieves the effect of accelerated pressure-injection combustion through the closed-end injection outlet.

[0036] As an embodiment of efficient gas premixing, the furnace cavity air inlet 3 is connected to a gas premixing pipe 9, which includes a premixing air inlet 10 and a premixing air outlet 11, and the diameter of the premixing air inlet 10 is smaller than the diameter of the premixing air outlet 11.

[0037] The premixed air inlet 10 is connected to an air volume adjusting member 12 for adjusting the amount of premixed air intake. The air volume adjusting member 12 includes a trumpet-shaped air intake expansion port 13, one end of which is provided with a straight tube body 14, which is slidably arranged in the premixed air inlet 10, and a locking member 15 for fixing is arranged between the straight tube body 14 and the outer wall of the premixed air inlet 10.

[0038] The air volume regulating member 12 is used by extending the trumpet-shaped air intake expansion opening 13 forward and backward, so that the air intake volume is adjusted accordingly according to the change in the size of the expansion opening.

[0039] As an embodiment of an efficient fixed installation structure, a fixing seat 16 for fixing a gas connector 18 is provided on the outer wall of the premixing air inlet 10 of the gas premixing pipe 9 .

[0040] The fixing seat 16 includes a C-shaped fixing frame 17, one side end of which is sleeved on the pipe body of the gas premixing pipe 9, and the other side end of the fixing frame 17 is provided with a connecting port 19 suitable for clamping the gas connector 18, and the bottom end of the fixing frame 17 is provided with a threaded hole 20 for installation and fixing.

[0041] like Figure 1-5 As shown, the working principle of the present invention is:

[0042] The gas is connected to the gas volume regulator 12 through the external gas connector 18. The gas volume regulator 12 delivers the gas from the premixing inlet 10 of the gas premixing pipe 9 and forms an efficient and stable premixed gas flow wave through the gas premixing pipe 9.

[0043] The premixed air flow premixed by the gas premixing pipe 9 is transported to the torch-shaped burner 1, and the first accelerating spraying furnace chamber 2, the second accelerating spraying furnace chamber 5 and the deep hole 8 of the torch-shaped burner 1 achieve the effects of accelerated spraying and full combustion, and finally reach a medium-pressure firepower of 15KW.

[0044] Compared with the "an energy-saving induced jet steam cabinet burner head, authorization announcement number CN204853485 U" disclosed in the prior art document, the steam cabinet burner head lacks a more effective accelerated spray pressure structure, so the actual combustion firepower of this type of steam cabinet burner head can only reach a medium and low pressure state of about 12KW, so the environmental protection and energy saving effect is still not good enough, and the furnace body of the steam cabinet burner head adopts a straight-through structure. Although the introduced gas can be premixed with natural wind, the effect is only lukewarm, and there is no more efficient and stable gas premixing and dispersion effect, and the combustion effect is uneven, which further limits the burner head from achieving a medium-pressure firepower state with stronger firepower and more environmental protection and energy saving.

[0045] It can be seen that compared with the traditional medium and low pressure firepower of about 12kw, the medium pressure firepower of 15KW that can be achieved by the present invention can achieve a more energy-saving and environmentally friendly effect, and can be applicable to natural gas sources and liquefied gas sources. It has a very broad prospect when applied to commercial stoves with huge energy consumption.

[0046] The torch-type energy-saving and environmentally friendly burner head of the present invention was commissioned to the "National Gas Appliance Product Quality Supervision Center (Foshan)" for testing. The test results showed that the tested items met the requirements of CJ / / T1872013 "Gas Steamer" and GB 30531-2014 "Energy Efficiency Limit Values ​​and Energy Efficiency Grades of Commercial Gas Cookers" standards.

[0047] Especially in the inspection project of heat flow accuracy, the measured heat flow reached 49.36KW, the rated heat flow reached 50KW, and the thermal energy efficiency value reached 81.3%. The thermal energy efficiency value is significantly higher than the average value of 70%, far exceeding the national first-level energy efficiency standard, and the energy-saving effect is obvious.

[0048] The number, size and position of parts in this solution can be changed according to the usage to derive a variety of products with different functions. The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
