Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a flame-gathering burner with high-efficiency energy-gathering multi-gas-channel multi-oxygen-supplementing technology. Background Art

[0002] The concentrated flame burner is a specially designed combustion device. Its main features are multi-channel and multi-ring combustion in the central area. The flame holes on the outer cover are designed with the inner flame holes angled inward, and the gas combustion is mainly concentrated in the inner flame area. Generally, the combustion process is the mixing and burning of combustible gas and oxygen under specific conditions to release heat. In the burner, by controlling factors such as the supply method and mixing ratio of gas and air and the structural design of the burner, the outer cover combustion flame is concentrated toward the internal center point, making the combustion heat more concentrated. The outer cover burner flame burns toward the central burner, and the flames gather and move closer to form a specific high-heat area. The heat is highly concentrated and does not diffuse or lose outward. The heat gathers at the bottom of the pot and burns close to the bottom of the pot. The flame does not wrap around the pot, thereby achieving the purpose of improving heat energy concentration, improving combustion thermal efficiency, and achieving the purpose of high efficiency and energy saving.

[0003] However, conventional burners in the prior art suffer from the problem of the flame wrapping around the edge of the pot, spreading outward, causing heat loss, flame instability, easy flame flying, and flame separation. The flame separation results in uneven heating due to heat dissipation, inability to fully burn the gas, poor heating effect, low thermal efficiency, high carbon monoxide emissions, and easy excessive flue gas, which is not energy-efficient. Therefore, in order to address the above problems, a new flame and energy-gathering burner is proposed that can solve the above problems. Utility Model Content
