Air and gas supply structure of gas radiant furnace

Abstract

An air and gas supply structure for the gas radiant furnace comprises a mixing tube, an air supply tube and a gas supply tube. The air supply tube and the gas supply tube are disposed axially along the mixing tube. A gas mixing device disposed in the air supply tube can make the air flowed into the tube have the uniform flow rate. The uniform flow rate of the air can minimize the flow resistance of the air and gas to reduce the flowing noise while mixing the air and gas fully and uniformly.

Description

technical field [0001] The present invention relates to a gas radiant furnace, in particular to an air supply pipe and a gas supply pipe for a gas radiant furnace and a gas supply structure. Background technique [0002] Generally speaking, the gas radiant furnace is a kind of heating equipment, that is, the mixed gas formed by the mixture of fuel and air will produce radiant body when burning, and the radiant body will generate radiant energy when heated, under the action of this radiant energy, the gas The radiant oven can heat and cook the object to be heated. [0003] Below, the structure of the gas radiation furnace under the prior art will be described in detail with reference to the accompanying drawings. [0004] figure 1 It is a schematic sectional view of a gas radiation furnace in the prior art, figure 2 yes figure 1 Cross-sectional view of the air flow velocity distribution inside the air supply pipe. [0005] Such as figure 1 As shown, the air and gas sup...

Problems solved by technology

[0013] In this way, the speed of the air flowing into the mixing tube 5 is not uniform and cannot be mixed well with the gas. Therefore, while the combustion stove 6 causes incomplete combustion, uneven and eccentric pressure is caused on the stove pad 7 during the combustion process. Flame distribution, reducing the heating efficiency of the heated body
