Problems solved by technology

[0002] The currently used gas burners have high requirements on gas quality. When the gas is mixed with tar, coal powder, fine wood powder and other impurities, it is easy to cause problems such as pipe blockage, resulting in black smoke, nitrogen oxides and other air pollutants. And because the gas travel speed is not high, the combustion is not violent enough, and the combustion is not complete, so the temperature of the flue gas cannot meet certain specific needs.

Embodiment Construction

[0018] Such as figure 1 As shown, the present invention includes a cylinder body 2, a primary air distribution pipe 3, a gas pipe 4 and a secondary air distribution pipe 5. The cylinder body 2 is a cylindrical structure with both ends sealed, and the inner wall of the cylinder body 2 is provided with a thermal insulation and refractory layer. In the embodiment, a cylindrical combustion chamber is formed inside the cylinder body 2, and the cylinder wall of the cylinder body 2 is respectively connected with the primary air distribution pipe 3, the gas pipe 4 and the secondary air distribution pipe 5,

[0019] The primary air distribution pipe 3 is connected to the low-temperature end of the cylinder body 2, and communicates with the combustion chamber along the outer circumferential direction of the circular section of the combustion chamber. The included angle between the axis of the primary air distribution pipe 3 and the axis of the cylinder body 2 is a spiral Angle α, the ga...

Abstract

The invention relates to a spiral gas combustor. The spiral gas combustor comprises a cylinder, a gas pipe, a primary air distribution pipe and a secondary air distribution pipe, wherein the gas pipe and the primary air distribution pipe are respectively connected with the low-temperature end of the cylinder and are communicated with a combustion chamber in the outer circumferential direction of the circular cross section of the combustion chamber; a spiral angle alpha is formed between the axis of each of the gas pipe and the primary air distribution pipe and the axis of the cylinder; a flame jet nozzle is arranged at the high-temperature end of the cylinder; the secondary air distribution pipe is connected with the cylinder between the gas pipe and the flame jet nozzle at the same spiral angle alpha. According to the spiral gas combustor, the combustion path of a gas is designed into a spiral shape, and a secondary air distribution technology is used, so that the combustion stroke of the gas is greatly prolonged under the condition of fixed volume of the cylinder; the gas is combusted more uniformly; various pollutants caused by incomplete combustion are avoided; the travelling speed of a fuel is improved, so that the combustion is more drastic.

Description

technical field [0001] The invention relates to the field of burners, in particular to a helical gas burner. Background technique [0002] The currently used gas burners have high requirements on gas quality. When the gas is mixed with tar, coal powder, fine wood powder and other impurities, it is easy to cause problems such as pipe blockage, resulting in black smoke, nitrogen oxides and other air pollutants. And because the gas travel speed is not high, the combustion is not violent enough, and the combustion is not complete, so the temperature of the flue gas cannot meet certain specific needs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a helical gas burner, which can fully burn gas mixed with various impurities such as tar, coal powder, fine wood powder, etc., avoiding pipe blockage, Eliminate the generation of air pollutants such as black smoke and nitrogen oxides; increase the c...
