Low-nitrogen combustor capable of achieving intensive mixing

Abstract

The invention relates to the technical field of environmental protection, and discloses a low-nitrogen combustor capable of achieving intensive mixing. The low-nitrogen combustor capable of achieving intensive mixing comprises a fixed barrel, a rotating barrel I and a fuel barrel, wherein the fixed barrel comprises an air cavity, a middle cavity, a combustion cavity and a segmentation plate; the air cavity is separated from the combustion cavity through the segmentation plate; the middle cavity communicates with the combustion cavity; one side of the air cavity communicates with an air inlet pipe; the middle cavity is movably connected with a rotating cylinder I in a sleeved mode; one side of the rotating cylinder I is fixedly connected with a driving gear; the center of the other end of the rotating cylinder I is fixedly connected with a combustion nozzle; and the same end of the rotating cylinder I is fixedly connected with a fire maker. According to the low-nitrogen combustor capable of achieving intensive mixing provided by the invention, by designing the fixed barrel, the fuel barrel and the rotating barrel, a large amount of fuels and a small amount of air can intermittently enter a mixing cavity and are rapidly and uniformly mixed in a rotating and direct-impact manner under the influence of high and low pressure differences, so that the excess air coefficient is reduced, the combustion reaction is promoted, and the generation of nitrogen oxides is reduced from multiple aspects.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a well-mixed low-nitrogen burner. Background technique [0002] Low-nitrogen burners refer to burners with low emissions of nitrogen oxides during fuel combustion. The formation of nitrogen oxides generally occurs in the following two situations when the burner is burning, namely, insufficient fuel combustion, flue gas and air staying at high temperature The flame zone oxidizes with the nitrogen and oxygen elements in the air for too long to form nitrogen oxides, and the nitrogen oxides produced by insufficient fuel combustion are the most. [0003] In order to reduce the formation of nitrogen oxides, an existing low-nitrogen burner will mix with cyclone air when the fuel is sprayed from the nozzle, so that it can be fully burned after being ignited, but this method makes the fuel During the period of time, there is less air that can be mixed, and the effect of ...
