Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a liquid fuel gasification burner. Background Art

[0002] Existing household water heaters are all gas water heaters, which use gas fuels such as natural gas as fuel for combustion and heating. However, with the development of liquid fuels, the use of fuels has begun to shift to safe fuels with relatively high flash points - liquid fuels (coal-based liquid fuels). Among them, coal-based liquid fuel for cooking stoves is a non-toxic, harmless, high-flash-point, clean fuel for cooking stoves made from Fischer-Tropsch synthesis hydrocarbons, industrial white oil, high-flash-point hydrocarbon compounds, etc., compounded with high-molecular oxygen-containing compounds and additives. It is mainly composed of alkanes.

[0003] According to patent number CN221705495U, a utility model patent for a high-flashpoint liquid fuel burner includes a combustion chamber, a ventilation pipe fixedly connected to one side of the combustion chamber, a blast chamber provided at the end of the ventilation pipe away from the combustion chamber, a mounting structure provided between the bottom of the blast chamber and the ventilation pipe, a combustion device fixedly connected to the bottom of the combustion chamber, a windshield fixedly connected around the outside of the combustion device, the bottom of the windshield fixedly connected to the bottom of the combustion chamber, and the top of the windshield fixedly connected to the combustion bowl. The advantages of this utility model over existing technologies are: the electric heater heats the bottom of the combustion chamber to conduct heat throughout the burner, and when the fuel flows into the combustion chamber through the oil nozzle, it is instantly vaporized. The firepower is controlled by adjusting the handle oil valve and the fan speed, so that the fuel is fully vaporized and burned, saving fuel and reducing emissions for environmental protection. At the same time, when the blast chamber is installed, it can be installed by snapping it onto the end of the ventilation pipe away from the combustion chamber through the mounting structure, making installation simple and quick.

[0004] Although the above technical solution can gasify the liquid fuel and make the fuel fully gasified and burned, the fuel is sprayed vertically from the bottom of the combustion chamber when burning in the combustion chamber. When the firepower is increased, the fuel will splash out of the combustion chamber, which poses a certain safety hazard. Utility Model Content
