Embodiment Construction

[0024] The structure of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0025] A kind of biogas burner of the present invention comprises: injector and nozzle; figure 1 As shown, the mouth of the nozzle is provided with several small-diameter passages, and the inner cavity of the nozzle is straight cylindrical. The several small apertures in the mouth are arranged in a quincunx shape and are connected, such as figure 2 As shown, the nozzle cavity is tapered. Or the several small apertures in the mouth are separated in a ring shape, such as image 3 As shown; the annular small-aperture multi-layer setting, the inner aperture is small, and the outer aperture is large, such as Figure 4 shown.

[0026] like Figure 5 and 6 As shown, the inlet end of the introduction section is evenly provided with a circle of small holes along the side wall (only one small hole is shown in the figure), so that the...

Abstract

The invention relates to a biogas burner which comprises an ejector and a nozzle. The biogas burner is characterized in that the ejector comprises an inlet segment and a mixing segment which are coaxial. The mixing segment is larger than the inlet segment in diameter, so that a gap is formed to guide in air for mixing. An opening of the nozzle is provided with a plurality of small-diameter channels. The channels are distributed in a quincuncial form and communicated, or disposed at intervals in a circle. The circular small-diameter channels are in multiple levels, and the inner channels are smaller than the outer channels in diameter. The side wall of the inlet end of the inlet segment is evenly provided with a circle of pores. The side wall of the upper end of the mixing segment is evenly provided with a circle of pores. Swirl blades are disposed in the mixing segment or inlet segment. A gridded flame stabilizer is disposed at the upper end of the mixing segment. The biogas burner allows for safety, high efficiency, pollution-free combustion and the like of biogas in a fermented biogas treatment and utilization system.

Description

[0001] This application is a divisional application of a patent application with an application date of December 29, 2009, an application number of 200910265344.4, and an invention title of "biogas burner". technical field [0002] The invention relates to the structure of a burner, in particular to a biogas burner. Background technique [0003] Fermentation biogas is the gas produced by anaerobic fermentation of waste such as domestic garbage, feces, sludge, sewage, etc. It is mainly composed of methane, carbon dioxide, water vapor and various trace impurities. [0004] The collection and utilization of fermented biogas has been paid more and more attention by people, and because these gases are all from waste fermentation, they are renewable energy sources, their utilization and consumption can not only replace non-renewable fossil fuels, but also reduce greenhouse gases emissions. [0005] However, in the fermentation biogas treatment and utilization system, due to the m...
