AI Technical Summary

Technical Problem

Existing burners cannot form a central direct injection flame in the middle of the inner ring flame, resulting in a low rated heat load efficiency, typically 5.2 kW.

Method used

A center-fire burner is installed in the burner, including a center-fire gas passage, a center-fire nozzle, and a center-fire injector. The gas is controlled by a plug valve to form a direct central injection flame at the center-fire outlet, thereby increasing the firepower and improving the thermal load efficiency.

Benefits of technology

The rated heat load efficiency was improved from 5.2 kW to 5.7 kW, enhancing the burner's firepower output.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0015] Example

[0016] See Figs. 1 to 3 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0017] The high-power burner with central direct injection in this embodiment includes a burner body 1 and a central fire burner 2. The burner body 1 includes an ejector 11, a gas distribution plate 12, an inner ring flame cap 13, an outer ring flame cap 14, an ignition needle 15, and a thermocouple 16. The gas distribution plate 12, the ignition needle 15, and the thermocouple 16 are all mounted on the ejector 11, and the inner ring flame cap 13 and the outer ring flame cap 14 are both mounted on the gas distribution plate 12.

[0018] In this embodiment, the ejector 11 is provided with an inner ring fire gas passage 17, an outer ring fire gas passage 18 and a central fire gas passage 19. The central fire burner 2 is equipped with the central fire gas passage 19, the inner ring burner cap 13 is equipped with the inner ring fire gas passage 17, and the outer ring burner cap 14 is equipped with the outer ring fire gas passage 18.

[0019] The central flame burner 2 in this embodiment includes a central flame base 21, a central flame nozzle 22, and a central flame ejector tube 23. The central flame outlet hole 24 is located in the middle of the inner ring flame cover 13. The central flame ejector tube 23 is installed in the central flame gas passage 19. The central flame nozzle 22 is installed on the central flame base 21. The central flame nozzle 22, the central flame ejector tube 23, and the central flame outlet hole 24 are arranged sequentially from bottom to top.
