Embodiment Construction

[0025] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0026] see Figure 1 to Figure 3 , The combustion air gun device 1 of the present invention includes a gas distributor 11 , a first air gun 12 , a second air gun 13 and a third air gun 14 . The gas distributor 11 includes a gas channel. The first air gun 12, the second air gun 13 and the third air gun 14 are uniformly arranged in circulation on the gas distributor 11 to form a space 15 and any one of the air guns is adjacent to the other two types of air guns. Specifically, in this In the embodiment, any first air gun 12 is adjacent to the second air gun 12 and the third air gun 13, any second air gun 12 is adjacent to the first air gun 12 and the third air gun 13, and any third air gun 13 is adjacent to the third air gun 13. An air gun ...

Abstract

The invention discloses a combustion gas gun device, which comprises a gas distributor and at least two gas guns, wherein the gas distributor comprises a fuel gas channel; an injection port connectedwith the flue gas channel is formed on each gas gun; the at least two gas guns are arranged on the gas distributor and formed space; and injection directions of the injection ports of the at least twogas guns are towards at least two combinations of the inside, the lateral side, and the front of the space, so as to enable the gas gun device to inject flue gas towards at least two directions of the inside, the side, and the front of the space. The combustion gas gun device solves the problem of uneven and concentrated flame injection, and also solves the problem that the central gas volume cannot be ensured due to the inner injection port.

Description

technical field [0001] The invention relates to an ultra-low nitrogen burner, in particular to a combustion air gun device for the ultra-low nitrogen burner. Background technique [0002] Most of the burners on the market use a single type of gas air gun, and the injection holes of the gas air gun are all in the form of round holes, and the injection direction is mostly in the front direction of the axis of the burner and with a certain outward / inward angle; the gas volume will vary. Too concentrated, uneven gas distribution, and central gas volume cannot be guaranteed. Contents of the invention [0003] The problem solved by the invention is that in the prior art, the gas distribution is uneven and the central gas volume cannot be guaranteed. [0004] To solve the above problems, the present invention provides a combustion air gun device, which includes a gas distributor, a first air gun, a second air gun and a third air gun. The gas distributor includes a gas channel, ...
