Description

Technical Field

[0001] This utility model belongs to the field of burners, specifically a flat flame burner. Background Technology

[0002] Existing flat-flame burners typically have a relatively simple structure, with only one fuel injection hole at the burner head. Fuel is ejected at high speed from this single hole, mixes with the rotating airflow within the combustion chamber, or at the combustion chamber outlet, and ignites. The flame root is relatively concentrated near the single-hole outlet and then gradually expands outward to form a planar flame. For example, CN202411329926.5 describes a premixed combustion device with a central hole. This combustion device can only be used to study single-hole combustion. Multi-hole combustion is also of great significance for the study of flat-flame burners. Existing premixed combustion devices cannot study the characteristics of multi-hole combustion phenomena, whether there is crosstalk during multi-hole combustion, whether the flame is enhanced or weakened during multi-hole combustion, or whether the arrangement of holes affects the flame. Summary of the Invention

[0003] The purpose of this invention is to address the problems in the prior art by providing a flat flame burner.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A flat flame burner includes a base and a lower shell and an upper shell mounted on the base, and a fixed platform located between the lower shell and the base. The inner side of the upper shell is provided with a protective gas ring, an isolation ring and a sintering plate in sequence. The sintering plate is provided with nine combustion holes, and a fuel pipe is inserted into each hole. The fuel pipe extends to the bottom of the base.

[0006] As a further optimization of this utility model, the nine combustion holes are arranged in a 3×3 matrix.

[0007] As a further optimization of this utility model, the sintering disc is internally wrapped with a spiral coil. The inlet of the spiral coil is connected to a coolant inlet 1 via a water pipe, and the inlet of the spiral coil is connected to a coolant outlet 1 via a water pipe. The coolant inlet 1 and the coolant outlet 1 are located on the lower shell.

[0008] As a further optimization of this utility model, the base is also provided with a coolant inlet 2 and a coolant outlet 2 located on the outside of the nine sets of fuel pipes.

[0009] As a further optimization of this utility model, a water-cooling liquid channel is formed between the inner cavity of the isolation ring and the lower shell, and both the second coolant inlet and the second coolant outlet are connected to the water-cooling liquid channel.

[0010] As a further optimization of this utility model, the enclosure area between the isolation ring, the protective gas ring and the lower shell is set as an isolation cavity for introducing protective gas.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) This flat flame burner is an improvement on the existing single-hole flat flame burner. Nine holes are opened in the sintering plate, and each hole is equipped with a fuel pipe. It is suitable for studying the multi-hole combustion characteristics of flat flame burners, including the characteristics of multi-hole combustion phenomena, whether there is crosstalk when multiple holes burn, whether the flame is enhanced or weakened when the holes burn, and whether the arrangement of holes affects the flame. Comparative experiments can also be conducted to test the flame characteristics of combustion with various layouts.

[0013] (2) Based on the improvement of the sintering plate, a dual-channel water cooling system was adopted. On the one hand, it can prevent the burner components from overheating and avoid problems such as uneven mixing of gas and air caused by overheating, thus ensuring the fullness of combustion. Appropriate cooling can make the temperature distribution of the combustion zone more reasonable. On the other hand, it increases the cooling area and the flow rate of the cooling medium, thereby reducing the temperature of the burner components more quickly and evenly, avoiding material deformation and damage caused by high temperature, and extending the service life of the burner.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 As shown, the flat flame burner of this embodiment includes a base 1, a lower shell 3 and an upper shell 8 mounted on the base 1, and a fixed platform 2 located between the lower shell 3 and the base 1. The inner side of the upper shell 8 is sequentially provided with a protective gas ring 5, an isolation ring 4, and a sintering plate 6. Nine combustion holes are perforated on the sintering plate 6, and a fuel pipe 7 is inserted into each hole, extending below the base 1. This is suitable for studying the porous combustion characteristics of the flat flame burner, including the characteristics of porous combustion phenomena, whether there is crosstalk when multiple holes burn, whether the flame is enhanced or weakened during hole combustion, and whether the arrangement of the holes affects the flame. Comparative experiments can also be conducted to test the flame characteristics of various combustion layouts.

[0022] Furthermore, the nine combustion holes are arranged in a 3×3 matrix, which allows for comparative experiments to test the flame characteristics of combustion in various layouts. This can be achieved by introducing fuel into the fuel pipe 7 of the selected combustion holes.

[0023] Furthermore, the enclosure area between the isolation ring 4, the protective gas ring 5 and the lower shell 5 is set as an isolation cavity 16 for introducing protective gas.

[0024] Furthermore, the sintering disc 6 is internally encased in a spiral coil 14. The inlet of the spiral coil 14 is connected to the coolant inlet 9 via a water pipe 15, and the inlet of the spiral coil 14 is also connected to the coolant outlet 10 via a water pipe 15. The coolant inlet 9 and the coolant outlet 10 are located on the lower housing 3. This is the first-channel water cooling. Compared with the prior art, extending the coolant inlet 9 and the coolant outlet 10 to the base 1, this flat flame burner adds a fixed platform 2, changing the orientation of the coolant inlet 9 and the coolant outlet 10 to horizontal, thus providing piping space for dual-channel water cooling.

[0025] Furthermore, a coolant inlet 21 and a coolant outlet 22 are provided on the base 1 outside the nine sets of fuel pipes 7.

[0026] Furthermore, a water-cooling channel 13 is formed between the inner cavity of the isolation ring 4 and the lower shell 3, and both the coolant inlet 11 and the coolant outlet 12 are connected to the water-cooling channel 13. This is the second-channel water cooling. Based on the improvement of the sintering plate, a dual-channel water cooling is adopted. On the one hand, it can prevent the burner components from overheating and avoid problems such as uneven mixing of gas and air caused by overheating, ensuring complete combustion. Appropriate cooling can make the temperature distribution in the combustion zone more reasonable. On the other hand, it increases the cooling area and the flow rate of the cooling medium, thereby reducing the temperature of the burner components more quickly and evenly, avoiding material deformation and damage caused by high temperature, and extending the service life of the burner.

[0027] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
