Problems solved by technology

[0003] However, during the use of the existing fully premixed metal fiber burner, it was found that the mixing uniformity and circulation dispersion effect of the mixed gas in the premixed unit were not good, resulting in unstable combustion of the fully premixed metal fiber burner

Abstract

The invention discloses a full pre-mixing metal fiber burner. The full pre-mixing metal fiber burner comprises a draught fan, a pre-mixing chamber and a burning head. An air outlet of the draught fan is connected with the front end of the pre-mixing chamber; the rear end of the pre-mixing chamber is connected with the burning head, an ignition assembly and an air distributing ring are arranged in the pre-mixing chamber, the ignition assembly is located at the rear end of the pre-mixing chamber, and the air distributing ring is connected with a fuel gas inlet of the side wall of the pre-mixing chamber; and an air mixing wheel is arranged in the burning head. According to the full pre-mixing metal fiber burner, the mode that a metal fiber surface burning head is additionally provided with an air fuel gas mixing structure is adopted, thus air and fuel gas are mixed twice before burning, mixing is more even, air supplying is sufficient, and generation of NOx and CO is inhibited.

Description

technical field [0001] The invention relates to the technical field of gas burners, in particular to a fully premixed metal fiber burner. Background technique [0002] In boiler manufacturing enterprises, especially for standard three-pass gas-fired boilers, if the traditional burner is used, a large amount of nitrogen and oxygen in the air will be catalyzed to form nitrogen oxides due to the existence of local high temperature, and the emission of nitrogen oxides will have a serious impact on the atmosphere. pollution; while the fully premixed burner fully premixes the fuel and air before combustion, so it has a large degree of complete combustion and higher efficiency. The metal fiber burner that has appeared in recent years is a fully premixed burner, with special metal fibers as the combustion surface, which makes the gas combustion very stable and the temperature distribution is uniform, and there is no local high temperature, so the formation of NOx is suppressed.
