Description

Technical Field

[0001] This utility model relates to the field of gas burner technology, and specifically to an energy-saving gas burner structure. Background Technology

[0002] Existing gas burners typically employ a premixed structure, comprising components such as a gas nozzle, air inlet, premixing chamber, and burner head. Gas is injected into the premixing chamber through the gas nozzle, where it is initially mixed with air before being discharged through the flame holes on the burner head surface for combustion.

[0003] Traditional burners suffer from low combustion efficiency due to uneven mixing, and unburned gas is directly emitted, resulting in energy waste. Furthermore, the high-temperature area of ​​the burner head lacks heat insulation, causing a large amount of heat to be lost through radiation. To address these issues, we propose an energy-saving gas burner structure. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low combustion efficiency caused by uneven mixing in traditional burners, energy waste caused by the direct emission of unburned gas, and lack of heat insulation protection in the high-temperature area of ​​the burner head, resulting in a large amount of heat loss through radiation. This invention provides an energy-saving gas burner structure.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An energy-saving gas burner structure includes a gas burner body, an insulating ceramic mounting base fitted around the outer ring of the gas burner body, multiple conical guide shrouds on the upper side of the insulating ceramic mounting base, and a bent guide edge fixedly connected to the upper end of each conical guide shroud. Multiple rows of connecting guide holes are equally spaced on the conical guide shrouds, and the connecting guide holes on the middle conical guide shroud and the connecting guide holes on the conical guide shrouds on both sides are staggered. A reflector is provided on the bottom outer side of the insulating ceramic mounting base.

[0007] Furthermore, the inner wall of the reflective disc has an arc-shaped structure, and an aluminum foil reflective layer is provided on the inner wall of the reflective disc.

[0008] Furthermore, the upper end of the heat-insulating ceramic mounting base has multiple annular slots corresponding to the bottom of multiple conical air guides, and the bottom of the multiple conical air guides is fixedly connected with mating edges, and the multiple mating edges are inserted and fixed into the annular slots one by one.

[0009] Furthermore, a ceramic flame stabilizer plate is provided at the upper end of the burner head of the gas burner body. The ceramic flame stabilizer plate has a porous honeycomb structure. A docking hole is provided at the upper end of the gas burner body, and multiple fixing posts are provided at the bottom of the ceramic flame stabilizer plate corresponding to the docking hole at the upper end of the gas burner body.

[0010] Furthermore, the upper end of the ceramic flame stabilizer plate is evenly distributed with multiple wavy flame stabilizer teeth.

[0011] Furthermore, a fixing ring is fixedly connected to the bottom of the inner cavity of the heat-insulating ceramic mounting base. The fixing ring is an annular structure with multiple connecting columns on the side wall.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a multi-ring conical guide shield. The conical guide shield generates gradient turbulence, which, combined with the guiding effect of the bent guide edges, creates secondary mixing, significantly improving the uniformity of gas-air mixing and enhancing combustion efficiency. Furthermore, the bent design of the multi-ring conical guide shield extends heat exchange time, increasing the utilization rate of combustion heat energy. The included reflector discs reflect heat radiation, reducing heat loss and effectively improving the working efficiency of the gas burner. Simultaneously, the heat-insulating ceramic mounting base effectively isolates heat from the high-temperature area of ​​the burner head, reducing heat loss and further improving heat utilization. In addition, this utility model has a reasonable structural design, stable and reliable connections between components, and is easy to disassemble and maintain, reducing operating costs and possessing broad application prospects.

[0014] 2. This utility model uses multiple ring slots and edge-to-edge insertion for fixing, which facilitates the assembly and disassembly of the conical fairing, further improving the stability of the conical fairing installation and making it easier for later maintenance and replacement.

[0015] 3. This invention utilizes a ceramic flame stabilizer plate. The porous structure of the ceramic flame stabilizer plate creates micro-vortexes, improving flame stability and further reducing flameout and backfire, thus enhancing the burner's safety and stability. Simultaneously, the ceramic flame stabilizer plate possesses excellent high-temperature resistance and thermal shock resistance, enabling stable operation for extended periods in high-temperature environments and extending the burner's service life.
