Embodiment 1

[0029] Such as Figure 1 to Figure 6 As shown, this example provides an ammonia gas burner, including a fuel inlet F1, a fuel inlet F2, an air inlet A1, an air inlet A2, an ignition device 1, a cylinder body 2, an expansion section 3, heat storage and stable combustion Body 4 and inner combustion chamber 5.

[0030] The cylinder 2 is provided with an igniter device 1 extending into the inner combustion chamber 5. The igniter device 1 is an existing structure well known in the art, and its connection with the cylinder 2 adopts a method well known to those skilled in the art. The existing connection mode of , will not be introduced in detail here.

[0031] Such as figure 2 , the fuel inlet F2, the air inlet A1, and the air inlet A2 enter the cylinder along the tangential direction.

[0032] Such as image 3 , the barrel is divided into inner fuel passage 21, inner air passage 22, outer gas passage 23, outer air passage 24 from inside to outside, inner fuel passage 21, inner...

Embodiment 2

[0039] Such as Figure 7 , The heat storage and combustion stabilization body 4 is a circular mesh structure, the inside is a heat storage body, the outside is an outer air flow channel, and swirling blades are arranged in the outer air flow channel.

Abstract

The invention discloses an ammonia gas burner, which comprises a cylinder body; an expansion section is formed on the front portion of the cylinder body; a heat storage stable combustion body is formed on the front portion of the expansion section; an inner combustion chamber corresponding to the heat storage stable combustion body is formed in the expansion section; an inner fuel channel, an inner air channel, an outer fuel gas channel and an outer air channel are sequentially arranged on the barrel from inside to outside; the inner fuel channel and the inner air channel are communicated with the inner combustion chamber; the outer fuel gas channel and the outer air channel extend to the heat storage stable combustion body; and flow equalizers are arranged in the inner fuel channel, the inner air channel, the outer fuel gas channel and the outer air channel, so that the combustion stability and the conversion efficiency of ammonia gas can be better improved.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to an ammonia burner. Background technique [0002] Ammonia is an extremely liquefied gas that can be liquefied under pressure at room temperature. Ammonia is an important chemical raw material, mainly used in the manufacture of nitrogen fertilizers and compound fertilizers. Ammonia is industrially passed through N by the Haber method 2 and H 2 It is made by direct compounding under the condition of high temperature and high pressure and the presence of catalyst, N 2 Usually derived from air, H 2 Usually derived from fossil fuels. [0003] Electrolytic hydrogen production has been limited by the cost of hydrogen production and has not been widely promoted. At present, in the case of large-scale promotion of new energy and renewable energy, power grid peak regulation has become the key to the safe operation of the power grid. The price of new energy power generation is gradual...
