Embodiment 1

[0024] Such as figure 1 As shown, a high-efficiency and clean gas-liquid dual-fuel dual-swirl burner disclosed in this embodiment includes a large-diameter connecting pipe 1, a small-diameter connecting pipe 2, a hexagon socket head cap screw 3, a first swirl block 4, a second Swirl block 5, axial liquid atomizer 6 and hex nut 7. The diameter of the large-diameter connecting pipe 1 is 30mm, and the diameter of the small-diameter connecting pipe 2 is 15mm. The small-diameter connecting pipe 2 is installed in the groove of the second swirl block 5 . The material of the large-diameter connecting pipe 1 and the small-diameter connecting pipe 2 is quartz glass. Such as image 3 As shown, the second swirl block 5 has four tangential inlets, and has gas inlet holes corresponding to the four tangential inlets. The second swirl block 5 is used to heat the axial liquid atomizer 6, And mixed with the gas evaporated from the axial liquid atomizer 6 for combustion. Install the large-d...

Abstract

The invention discloses an efficient clean gas-liquid dual-fuel dual-vortex burner, and belongs to the field of burning. The efficient clean gas-liquid dual-fuel dual-vortex burner comprises a large-diameter connecting pipe, a small-diameter connecting pipe, an inner hexagonal screw, a first vortex block, a second vortex block, an axial liquid atomizer and a hexagonal nut. Gas fuel and an oxidizing agent are introduced into a burning chamber from N1 tangential inlets of the first vortex block for mixed burning; air injected coaxially and tangentially into the second vortex block is heated by the high-temperature gas generated during mixed burning; the heat of the heated air is transferred to a coaxial liquid fuel line located in the second vortex block; through the heat transfer with the vortex air, the liquid fuel is boiled and evaporated, and is sufficiently mixed with the preheated air for combustion under the action of the vortex at an outlet of the liquid line, so that steady flame burning is realized and the operating cycle of the burner is extended. The technical problems to be solved by the invention are that the evaporation, atomization and pollutant discharge in the burning process of the liquid fuel are reduced, steady flame burning is achieved and the operation cycle of the burner is extended.

Description

technical field [0001] The invention belongs to the field of combustion, and relates to a gas-liquid dual-fuel double-swirl burner, in particular to an efficient and clean gas-liquid dual-fuel double-swirl burner. Background technique [0002] At present, fossil fuels are the main source of energy for social production and daily life, but the emissions of greenhouse gases, nitrogen oxides, sulfides, and soot produced by their combustion have brought increasingly serious environmental pollution problems and seriously affected people's daily life How to use fossil fuels more efficiently and environmentally friendly, and develop economical and environmentally friendly energy technologies with low pollutant emissions has become the focus of increasing attention. [0003] Environmental pollution caused by burning pollutants, such as smog, climate warming, acid rain and other issues, has been plagued by all aspects of human life. Environmental research scholars from various count...
