Ignition burner

Abstract

The invention relates to an ignition burner. The ignition burner comprises an elongated hollow pipe body, wherein the rear end of the pipe body is connected with a three-way joint through a front flange plate; a rear port of the three-way joint is provided with a rear flange plate; the rear flange plate is provided with a gas inlet and an electrode rod; a side port of the three-way joint is an airinlet; the front end of the pipe body is provided with a mixing nozzle; the front end of the mixing nozzle is provided with an ignition pipe; the mixing nozzle is of a conical structure; a nozzle isarranged at the center of the mixing nozzle; a combustion-supporting hole is formed in the side wall of the mixing nozzle; and the front end of the electrode rod is positioned at the side part of thenozzle. According to the ignition burner, a long-distance premixing mode is adopted, so that the fuel gas is fully mixed with air, the generated conductive ions are rich, the combustion effect is good, and the flame is stable; and after the gas is premixed, the aperture of the nozzle can be increased, and furthermore, the combustion-supporting hole is obliquely arranged, so that the blockage caused by the accumulation of dust is effectively prevented, the stable and reliable production is guaranteed, and the service life of the ignition burner is prolonged by 2-3 times compared with that of atraditional ignition burner.

Description

【Technical field】 [0001] The invention relates to the technical field of burners, in particular to an ignition burner. 【Background technique】 [0002] In a melting furnace, the ignition burner is the main component used for ignition. The currently used ignition burner includes a strip-shaped pipe body, the front end of the pipe body is the ignition port, the rear end of the pipe body is the air inlet, and an inner pipe is arranged in the pipe body, and the inner pipe extends from the air inlet to At the ignition port, the inner tube is used for gas delivery, and the air is passed between the tube body and the inner tube, and an ignition electrode and a detection electrode are also provided. When in use, the gas input from the inner tube is mixed with air at the ignition port and ignited by the ignition electrode. The disadvantage of the currently used ignition burner is: because the ignition burner is usually set up inclined, in the smelting workshop with harsh environment...

AI Technical Summary

Problems solved by technology

The disadvantage of the currently used ignition burner is: because the ignition burner is usually set up inclined, in the smelting workshop with harsh environment, dust is easy to fall on the ignition port and block the gas outlet of the inner tube, causing failure

In addition, because the gas and air are mixed at the ignition port and then ignited, they cannot be fully mixed, and the conductive ions generated are not sufficient, which affects the combustion effect and the flame is also unstable.
