[0034] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] Example 1

[0038] A burner port structure for a burner comprises a burner plate 1, a main burner port 2, a flame stabilizing burner port 3 and a burner port body 4.

[0039] The burner plate 1 is arranged on the top of the burner cavity body 4, the main burner 2 and the flame stabilizing burner 3 are arranged on the burner plate 1 at intervals, and the area of ​​each main burner 2 is not less than 2.5mm 2 , no more than 3.5mm 2 , and each main burner 2 is provided with a flame stabilizing burner 3 on both sides, the main burner 2 and the flame stabilizing burner 3 are both higher than the burner plate 1, and the height of the flame stabilizing burner 3 is smaller than the main burner 2.

[0040] The burner structure of this embodiment achieves improved flame height through deep burner and large burner area, and combined with the flame stabilizing burner 3, the burner structure has both flame height and stable combustion, improving the applicability of low-pressure fierce fire stoves.

[0041] Example 2

[0042] A burner port structure, such as Figures 3 to 5 As shown, the burner cavity body 4 is arranged on the burner monolithic plate 5, the burner monolithic plate 5 is provided with a combustion gas inlet and a mixing chamber, the burner cavity body 4 is connected to the combustion gas inlet through the mixing chamber, and the height of the burner cavity body 4 is not less than 6 mm. The rest is the same as the embodiment 1.

[0043] Example 3

[0044] A burner port structure for a burner comprises a burner plate 1, a main burner port 2, a flame stabilizing burner port 3 and a burner port body 4.

[0045] When the fuel gas enters the burner mouth body 4 evenly from the lower part of the burner mouth, since the burner mouth body 4 is a constant pressure chamber, the combustible gas enters the main burner mouth 2 and the stabilizing flame burner mouth 3 respectively, and flows out from the main burner mouth 2 and the stabilizing flame burner mouth 3, forming a flame layer (including the main flame 6 and the stabilizing flame 7) on the burner surface.

[0046] Because of the need to obtain a high flame, the main burner 2 has a larger burner area. The combustible gas flowing out of the main burner 2 is maintained for a certain distance before being completely burned. However, since this burner is suitable for liquefied gas and natural gas, the calorific value of natural gas and liquefied gas is different, and the gas supply pressure is different, and the burner must be compatible with these two types of gas. After calculation and experiment, it is determined that the area of ​​a single main burner 2 shall not be less than 2.5mm 2 , not more than 3.5mm 2 , otherwise there will be problems of incomplete combustion and flashback.

[0047] In order to prevent flashback and human garbage from falling into the burner mouth and blocking the burner mouth during cooking, this embodiment adopts a deep burner structure. The burner depth h (the height of the flame stabilizing burner 3) is not less than 1mm, and the maximum depth is maintained in principle without fracture in the burner opening process.

[0048] In order to stabilize the main flame 6, the present embodiment is designed with a flame-stabilizing burner 3. There are four flame-stabilizing burners 3 on both sides of the main burner 2. The flame-stabilizing burner 7 generated by the flame-stabilizing burner 3 heats the root of the main flame 6, so that the main flame 6 is immediately ignited when the combustible gas flows out of the main burner 2, thereby stabilizing the combustion of the main flame 6. Otherwise, the flame separation and flame-out may occur, which seriously affects the emission flue gas indicators and the burner efficiency.

[0049] The main burner 2 and the flame stabilizing burner 3 are different in height (see Figure 2The height h of the flame stabilizing port 3 is generally 2 / 3-1 / 2 of the height S of the main flame port 2. Too high or too low will affect the flame stabilizing effect.

[0050] There are four flame stabilizing burners 3 on both sides of the main burner 2. For the reliability of flame stabilization, the distance C between the flame stabilizing burner 3 and the main fire hole 2 in the X-axis direction (the length direction of the burner plate 1) is 1.2-1.6mm. Too large or too small will affect the flame stabilization effect.

[0051] The flame stabilizing burners 3 are distributed on both sides of the main flame hole 2. In order to ensure the flame stabilizing coverage of the flame stabilizing flame 7, in addition to the above-mentioned distance of the flame stabilizing burners 3 in the X-axis direction, the position of the flame stabilizing burners 3 in the Y-axis direction relative to the main flame hole 2 is also specified, such as Figure 1 As shown, the flame stabilizing burners 3 are distributed at 1 / 4 and 3 / 4 of the extension direction of the main burner 2, that is, Lc / L=1 / 2 as shown in the figure.

[0052] The burner cavity body 4 is the key to forming a stable isobaric cavity. Since the deep burner has a large resistance, in addition to requiring a certain combustible gas pressure, it is necessary to ensure that every part of the burner cavity body 4 is in a combustible gas isobaric state. The combustible gas velocity flowing out of the burner is consistent, and the flame height is consistent, so the height of the burner cavity body is not less than 6mm.

[0053] Implementation effect:

[0054] like Figures 6 to 8 As shown, the burner structure of this embodiment is applied to a fire row burner, and it is found that under a gas pressure of 5000-2800Pa:

[0055] 1. Compared with Figures 9-10 The flame height of the single-piece fire row burner with a burner structure shown in the figure is increased from 4mm to 10mm, and the outer flame height is increased from 12mm to 25mm;

[0056] 2. Under both natural gas and liquefied gas conditions, stable combustion can be achieved by simply replacing the nozzle;

[0057] 3. Carbon monoxide emissions in flue gas are less than 0.01%;

[0058] 4. Whole set efficiency: 45.2% for stir-fry cooking, in line with national standard requirements.

[0059] The burner structure of the utility model can be adjusted in width and length according to the required power (the burner single piece should be adjusted at the same time) to meet the requirements of different users. However, the distribution and shape of the burner need to comply with the basic requirements of the utility model.

[0060] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
