Alcohol combustion stove and cold start ignition method thereof

Abstract

The invention relates to an alcohol combustion stove. The alcohol combustion stove comprises a fuel flow adjusting device, a gasification ring and a direct injection pipe which are sequentially connected through pipelines; a three-way switching valve is arranged on the pipeline of the fuel flow adjusting device and the gasification ring, the output end of the fuel flow adjusting device is connected with the end a of the three-way switching valve through the pipeline, the end c of the three-way switching valve is connected with the input end of the gasification ring through the pipeline, the end b of the three-way switching valve is connected with a fuel atomization nozzle, and the fuel ejection direction of the fuel atomization nozzle faces the gasification ring; and a temperature detection device used for detecting the temperature of the gasification ring is arranged on the gasification ring. The alcohol combustion stove further comprises an ignition device used for igniting the fuelsprayed out through the fuel atomization nozzle. The invention further relates to a cold start ignition method of the alcohol combustion stove. The alcohol combustion stove is simple in structure, lowin manufacturing cost and good in fuel gasification effect.

Description

technical field [0001] The invention relates to the field of alcohol combustion stoves, in particular to an alcohol combustion stove and its cold start ignition method. Background technique [0002] Chinese Patent Document No. CN107191976A discloses a liquid fuel stove, which includes a combustion gasification ring installed in the furnace cavity, a direct injection tube and a fire distributor.

By in...

AI Technical Summary

Problems solved by technology

[0003] The liquid fuel stove needs to be equipped with an electric heating gasification device so that it can quickly gasify the fuel during cold start, but the electric heating gasification device needs to add components such as electric control and power supply, resulting in high cost of the liquid fuel stove. The faster the gasification speed of the fuel, the higher the power of the electrothermal gasification device, and the higher the cost of electronic control, power supply and other components
