Embodiment Construction

[0016] Please refer to the attached figure 2 And attached image 3 As shown, the present invention is a fuel non-reversing regenerative burner gas spray gun, which includes a spray gun body 1, the spray gun body 1 is the prior art, and will not be repeated here.

[0017] The spray gun body 1 is provided with an ignition gas passage 2 , an ignition combustion air passage 3 , a main gas passage 4 and a combustion air passage 5 sequentially from inside to outside.

[0018] Both the front ends of the main gas passage 4 and the combustion air passage 5 are provided with zoom pipes 6 . The main function of the zoom tube 5 of the main gas channel 4 is to control the gas flow rate and injection angle, the inlet angle is 60-80 degrees, the outlet angle is 10-20 degrees, and the gas outlet flow rate is controlled to be 60-100 meters per Second. The inlet angle of the zoom pipe 6 of the combustion-supporting air channel 5 is 40-60 degrees, and the outlet angle is 5-20 degrees, which ...

Abstract

The invention relates to a fuel gas spray gun for a fuel non-reversing heat accumulation type combustor. The fuel gas spray gun comprises a spray gun body. An ignition fuel gas channel, an ignition combustion supporting air channel, a main fuel gas channel and a combustion supporting air channel are arranged in the spray gun body in sequence from inside to outside. The front end in the main fuel gas channel and the front end in the combustion supporting air channel are each provided with a contracted-expanded tube. A combustion stabilization hole plate is arranged in the combustion supporting air channel, provided with a premixed fuel hole and further provided with a flame detection electronic eye. The fuel gas spray gun for the fuel non-reversing heat accumulation type combustor has the advantages of being simple in structure and good in flame rigidity, saving fuel, being capable of achieving real-time monitoring and the like. The problem that a flame detection electronic eye cannot work stably due to the fact that an existing spray gun is poor in flame rigidity, flame lifting is caused and flame swings left and right is solved.

Description

【Technical field】 [0001] The invention relates to a component part of a burner, in particular to a gas spray gun for a fuel non-reversing regenerative burner, which belongs to the technical field of burners. 【Background technique】 [0002] The fuel non-reversing regenerative combustion system of the prior art is as attached to the instruction manual. figure 1 As shown, the large circle is the furnace body, the middle of the right side is the fuel spray gun 1', the two sides are the heat storage tank I2' and the heat storage tank II3', the heat storage tank I2', the heat storage tank II3' and the fuel spray gun 1' forms a certain angle, and the rear end of the fuel spray gun 1' is a four-way reversing valve 4'. During work, the fuel spray gun 1' continuously outputs fuel into the furnace. The combustion-supporting air is supplied by the fan 5', and is alternately sprayed out from the heat storage tank I2' and the heat storage tank II3' through the four-way reversing valve...
