Problems solved by technology

[0003] The present invention provides a methanol burner in order to solve the problem of insufficient combustion and the inability to shape the shape and length of the flame in the existing methanol burner
[0005] When the methanol burner is working, the atomized methanol is ignited, and its flame is forced to disturb the swirl under the action of the ceramic swirl in the flame swirler, so that the flame produces an axial and radial velocity superposition, and the methanol burns It is very sufficient and overcomes the problems of insufficient combustion and the inability to shape the shape and length of the flame in the existing methanol burner

Embodiment

[0028] Turn on the main fan 1, the pressurized methanol is atomized through the nozzle 3 and ignited by the arc of the ignition needle 2, the main fan 1 provides the air and axial wind pressure required for combustion, and the ignited methanol flame is blown into the flame swirler 11, Due to the axial wind pressure of the main fan 1, the ignited flame is forcibly disturbed by the ceramic swirl vanes 13 in the ceramic swirl tube 12, resulting in the superposition of axial and radial velocities to form a rotating flame. Flow to the outlet of the flame cyclone.

[0029] When the nitrogen oxides in the flue gas are high, adjust the air volume of the main fan so that the cyclone is a reducing atmosphere. At this time, a large amount of nitrogen oxides will not be produced. At the outlet of the flame cyclone 11, the secondary fan 9 The generated secondary air is transported to the outlet of the cyclone through the secondary air channel 8, so that the rotating flame and the secondary...

Abstract

The invention particularly discloses a methanol burner. The problems that an existing ethanol burner is insufficient in burning, and the shape and the length of the flames cannot be adjusted are solved. A through connection cylinder is arranged on an air outlet of a main draught fan, an ignition needle and a nozzle are arranged in the through connection cylinder, the other end of the through connection cylinder is sequentially connected with a hydrocyclone fixing flange and a hydrocyclone fixing cylinder, a secondary air inlet channel is formed in the connecting position of the hydrocyclone fixing flange and the hydrocyclone fixing cylinder, a secondary air pipe is arranged between the secondary air inlet channel and a secondary draught fan, a supporting rib plate is arranged on the inner wall of the hydrocyclone fixing cylinder, a flame hydrocyclone is clamped to the supporting rib plate, and comprises a ceramic hydrocyclone pipe, a secondary air flue is arranged in an annular gap between the outer wall of the ceramic hydrocyclone pipe and the inner wall of the hydrocyclone fixing cylinder, mounting holes are formed in the side wall of the ceramic hydrocyclone pipe, and a ceramic hydrocyclone piece is inserted in each mounting hole. Flames formed through methanol atomization ignition are subject to hydrocyclone operation, and the sufficient burning aim is achieved.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a methanol burner. Background technique [0002] With the application of clean energy more and more widely, methanol burners have been widely used. At present, the methanol burners on the market are used as methanol burners by replacing the methanol fuel with light oil burners. The combustion of methanol fuel is very different from the combustion of light oil fuel. The latent heat of methanol gasification is very large, which is about 3-4 times that of light oil. Due to the latent heat of gasification, the temperature of the combustion zone decreases, and many unburned methanol particles are also released. When discharged into the atmosphere, harmful substances such as formaldehyde will also be produced. For this reason, some people add various high-calorific-value ingredients to methanol, in order to make the fuel suitable for light oil burners; there are also people who use h...
