Problems solved by technology
[0002] The existing combustion system of fuel oil and gas, including the air distribution plate used for the accumulative combustion system of the aluminum melting furnace, its basic structure and composition are nothing more than setting a number of air distribution holes on the plate body as passages for supporting gas, and The passage holes for the supporting gas are almost all cylindrical through holes, and in order to make the fuel and the supporting gas mix uniformly and fully, the number of through holes is usually set relatively large, but despite this, such a structure has a great impact on the fuel and supporting gas. The improvement of mixing effect and combustion efficiency is still not ideal
Moreover, the contradiction between the flow rate of the air-supporting gas and power consumption of the existing structure of the air distribution plate is also prominent, and the distance of the flame spray and the power of the gas supply conflict with each other, and it is difficult to coordinate
As a result, the production energy consumption is high and the cost is high

Embodiment Construction
[0016] The present invention will be further described through embodiment now in conjunction with accompanying drawing.
[0017] Such as Figure 1-5 As shown, the air distribution plate is composed of a plate body 1, a fuel hole 2 as a fuel channel arranged on the plate body 1, and four waist-shaped horn holes (or waist-shaped circular table holes) arranged around the fuel hole 2 on the plate body 1 3, ignition gun hole 4, and ignition combustion air hole 5 etc. constitute. The inlet 3a of the waist-shaped horn hole 3 and the inlet 2a of the fuel hole 2 are respectively connected to the air supply pipe and the outlet of the fuel gun, and the outlet 2b of the fuel hole 2 and the outlet 3b of the waist-shaped horn hole 3 are connected to 6 of the mixing chamber. Fuel gas and combustion-supporting air are fully mixed in the mixing chamber 6 from the fuel hole 2 and the waist-shaped horn hole 3 respectively in the form of swirling flow, and then sent to the combustion furnace fo...

The invention discloses a wind distribution board which has simple structure, can improve the mixing effect and enhance the combustion efficiency. The wind distribution board comprises a combustion hole formed on a board body and a plurality of waisted horn holes formed around the combustion hole, wherein the axial lines of the waisted horn holes respectively oblique to the axial line of the combustion hole by 8-10 degrees in the X axis and the Y axis directions.
Description
Technical field: [0001] The invention relates to a combustion system, in particular to an air distribution plate used in a regenerative combustion system of a smelting furnace. Background technique: [0002] The existing combustion system of fuel oil and gas, including the air distribution plate used for the accumulative combustion system of the aluminum melting furnace, its basic structure and composition are nothing more than setting a number of air distribution holes on the plate body as passages for supporting gas, and The passage holes for the supporting gas are almost all cylindrical through holes, and in order to make the fuel and the supporting gas mix uniformly and fully, the number of through holes is usually set relatively large, but despite this, such a structure has a great impact on the fuel and supporting gas. The improvement of mixing effect and combustion efficiency is still not ideal. Moreover, the contradiction between the flow velocity of the air-support...
