Embodiment Construction

[0026] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. For the sake of clarity, various parts in the drawings have not been drawn to scale. Also, some well-known parts may not be shown. There are many specific details of the invention described below, but the invention may be practiced without these specific details, as will be understood by those skilled in the art.

[0027] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean being directly on another layer or another region, or Other layers or regions are also included between it and another layer or another region. And, if the part is turned over, the layer, one region, will be "below" or "beneath" the other layer, another region.

Abstract

The invention discloses a burner. The burner comprises a fan for supplying oxidant gas, a mixer connected with the fan, a burning head connected with the mixer and a swirler arranged in the burning head, wherein oxidant gas and fuel gas are mixed in the mixer to obtain a mixed gas; the mixed gas is jetted from the burning head; the swirler comprises a plurality of blades which radially extend from the swirler center to the periphery; and the plurality of blades are inclined at a preset angle relative to the axial direction of the burning head; and a plurality of first through holes are formed in each blade. According to the burner, the fuel gas and the oxidant gas are firstly mixed in the mixer and are jet through the swirler; the plurality of first through holes are formed in the plurality of blades of the swirler, and have a rectifying effect, and the mixed gas can be further mixed while turbulence of the mixed gas is realized, so that the fuel gas and the oxidant gas can be uniformly mixed more easily, and the length of the mixing section of the burner can be shortened.

Description

technical field [0001] The present invention relates to the field of industrial combustion equipment, more specifically, to a burner. Background technique [0002] Burner is a general term for devices that make fuel and combustion-supporting gas ejected and mixed in a certain way for combustion. According to its application neighborhood, it can be divided into industrial burners, burners, Mingyong burners, and characteristic burners. [0003] There are many types and specifications of industrial burners, including several major categories such as fuel oil, gas, and coal. Its application area is very wide, and industrial occasions that need to burn fuel to heat materials or react need to use burners. [0004] In order to ensure uniform temperature of combustion materials, reduce local high temperature phenomena, and reduce nitrogen oxide emissions during combustion, gas burners need to fully mix gas and assisted gas through mixers and other auxiliary devices. In the use of t...
