Smoke reflux vaporized alcohol-based fuel burner

Abstract

The invention discloses a smoke reflux vaporized alcohol-based fuel burner which comprises a shell, wherein the top of the shell is provided with a fuel pipeline, a catalytic reaction body is arranged in the shell, a smoke reflux passage is vertically arranged in the shell, the smoke reflux passage penetrates through the catalytic reaction body, a top cover is arranged above the smoke reflux passage, and a bottom cover is arranged at the bottom of the smoke reflux passage; and an outlet section of a fuel output pipe vertically extends upwards to a throat part of the shell from the lower part of the shell, and an igniter is arranged on the inner wall of the shell. Before the fuel is atomized, the alcohol-based fuel is heated by utilizing the heat produced by the burner, so that the tension of the alcohol-based fuel is reduced, and the atomizing effect is better; and when the smoke returns to a gas atomizing mixing area, not only the air can be preheated and the comprehensive utilization efficiency of the burner be increased, but also the heat in a flame burning area transfers towards a mixing space due to the refluxing of the smoke, the temperature in the flame burning area is reduced, the temperature of the entire burner is more uniform, and the carbon deposition produced by the liquid fuel due to the over-high temperature of the flame can be reduced.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to an alcohol-based fuel burner. Background technique [0002] Burners are widely used in industry, agriculture, transportation and daily life. In real life, there are mainly three types of burners: gas, liquid and solid. The combustion of liquid fuel needs to be refined through atomization and other methods to achieve high combustion efficiency. For example, the liquid fuel burner disclosed in Chinese invention patent application 201110405701.X directly uses the nozzle to atomize the liquid fuel, and then sets air around the flame. Supply port, enhanced combustion. The measures taken in the prior art have improved the combustion efficiency to a certain extent, but the atomized small particles ejected from the nozzle are directly burned, and the flame makes the liquid particles evaporate and burn, but the high temperature of the flame also directly carbonizes the inside of the liqu...

AI Technical Summary

Problems solved by technology

The measures taken in the prior art have improved the combustion efficiency to a certain extent, but the atomized small particles ejected from the nozzle are directly burned, and the flame makes the liquid particles evaporate and burn, but the high temperature of the flame also directly carbonizes the inside of the liquid, and the combustion does not occur. It is not very sufficient, and it is easy to deposit carbon after combustion, and the comprehensive heat utilization efficiency is still low
