Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kiln burner devices, and specifically refers to a premixed high-speed burner. Background Art
[0002] In the industrial field, high-speed burners are widely used in various combustion equipment to mix fuel and air and conduct sufficient combustion in the combustion chamber to generate heat energy or drive power equipment. However, there is a common problem with traditional burners, that is, the mixing of gas and air is uneven, resulting in incomplete combustion and low efficiency. When traditional burners mix gas and air, due to improper design or operation, the two cannot be evenly mixed. This unevenness may cause incomplete combustion of fuel in some areas, thereby reducing the combustion efficiency and increasing heat energy loss; in traditional designs, after gas and air enter the combustion chamber, the flow field distribution is uneven, and local oxygen-rich or fuel-rich areas may be formed, affecting the stability and efficiency of combustion.

[0026] The specific implementation process of the present utility model is as follows:
[0027] 1. The mixing process of gas and air: The gas enters the premixing chamber 1 through the gas inlet 6, and the air enters the premixing chamber 1 through the air inlet 7. The wind plates 12 inside the wind wheel mechanism 5 generate a strong air flow when rotating, quickly mixing the gas and the air.

Optimization of the intake direction: The intake directions of the gas and the air are tangent to the circular inner wall of the premixing chamber 1, ensuring that the gas and the air entering the premixing chamber 1 can drive the wind plates to rotate, mixing the two evenly and avoiding the problem of uneven local gas concentration.
[0029] 3. Functions of the baffle and through-hole: After air and gas are mixed inside the premixing chamber 1, they enter the combustion chamber 3 through the through-hole 9. The through-hole 9 on the baffle 8 helps to disperse and guide the mixed gas flow, ensuring the uniformity of the gas inside the premixing chamber, avoiding problems of local oxygen enrichment or fuel enrichment, and thus improving the combustion efficiency.
[0030] 4. Ignition and combustion process: The igniter 10 ignites in the premixed gas and air mixture, triggering a combustion reaction, generating high temperature and energy for industrial production or power drive.
