Embodiment 1

[0026] The purpose of this embodiment is achieved through the following technical solutions.

[0027] Such as figure 1 , 2 As shown, a porous jet burner based on internal and external swirl flow to promote liquid fuel atomization disclosed in this embodiment includes a quartz glass tube with an inner diameter of 48 mm), M6 hexagonal screws 2, front cover 3, and 0.5 mm thick copper gasket 4 , G1 / 8 quick pipe joint 7, back cover 8, gasket 9, M6 hex nut 10, small O-ring 11, large O-ring 12; also includes outer swirl block 5, jet-inner swirl block 6. The outer swirl block (5) has 4 tangential inlets tangent to the inner wall surface, the slit width of the tangential inlets is 0.5 mm, and has gas inlet holes corresponding to the 4 tangential inlets, so that the inlet The oxidant forms an external swirl close to the wall, such as the section at B-B image 3 shown. The jet-inner swirl block 6 has 4 evenly distributed inner swirl inlets with a width of 1mm, and the 4 evenly distri...

Abstract

The invention discloses a porous jet flow combustor capable of promoting atomization of liquid fuel based on internal and external rotational flow, and belongs to the field of combustion. The porous jet flow combustor comprises a quartz glass tube, a hexagonal screw, a front cover, a copper gasket, a rapid pipe connector, a rear cover, a gasket, a hexagonal nut, a small O-shaped ring and a large O-shaped ring and further comprises an external rotational flow block and a jet flow-internal rotational flow block. The external rotational flow block is provided with tangential inlets tangential to the inner wall face and gas inlet holes which correspondingly communicate with the tangential inlets, and therefore an introduced oxidizing agent forms the external rotational flow in close fit with the wall face. The jet flow-internal rotational flow block is provided with evenly-distributed internal rotational inlets. The external rotational flow block and the jet flow-internal rotational flow block form a two-rotational-flow structure. The porous jet flow combustor aims at achieving the technical effects that atomization and evaporation of liquid fuel during combustion are promoted, the mixing efficiency of the liquid fuel during combustion is improved, stable flame combustion is achieved, and the combustion efficiency is improved; the flame temperature is freely adjusted and controlled; and the service life of the combustor is prolonged.

Description

technical field [0001] The invention belongs to the field of combustion, and relates to a burner, in particular to a porous jet burner based on internal and external swirl flow to promote the atomization of liquid fuel. Background technique [0002] The current combustion of fossil fuels provides 80% of the energy for social production and daily life. With the continuous consumption of fossil fuels, how to use fossil fuels more efficiently and environmentally friendly and develop renewable energy has become the focus of increasing attention. Researchers from various countries are actively studying various combustion technologies, hoping to improve fuel combustion efficiency and alleviate energy shortages. Nowadays, renewable fuels such as methanol and ethanol have attracted the attention of scholars and government departments, but the related high-efficiency, clean and stable combustion technologies are still in the research stage, especially for the injection, evaporation, ...
