Problems solved by technology
[0003] At this stage, the fuel oil evaporation technology is used to improve the combustion efficiency. After the fuel oil evaporates, the fuel vapor in the central area of the combustion chamber is far away from the air intake hole of the combustion chamber wall, and the fuel vapor in the central area of the combustion chamber is not mixed with air sufficiently, so that the fuel oil Can't fully burn
[0004] Patent 201510641333.7 proposes a "camping combustion heating stove". After the device burns stably, the liquid fuel absorbs heat and vaporizes. When the air is not supplied, the combustion will be insufficient and the combustion efficiency will be reduced.

Abstract
According to the convex porous medium evaporative burner and the using method, after a glow plug reaches a burning state, fuel oil in a liquid fuel flow guide pipeline is supplied into a fuel oil evaporation loop, the fuel oil is absorbed by an oil absorption porous medium, and the fuel oil on the surface of the oil absorption porous medium is evaporated; air passes through the air guide channel and then passes through the air inlet holes in the wall surface of the inner barrel of the combustion chamber to form jet air, and the jet air is blown to the oil absorption porous medium and is fully mixed with fuel oil; when the glow plug reaches the ignition point of the fuel oil, the mixed gas of the fuel oil and air is ignited, and the upward blowing gas passes through the air return baffle, so that air in a flowing dead zone flows back to be blown to the oil absorption porous medium, evaporation is accelerated, the air is better mixed with the air, and the problems that in the prior art, combustion is insufficient, and the combustion efficiency is reduced are solved.
Description
technical field [0001] The invention belongs to the technical field of fuel evaporative burners, and in particular relates to a convex porous medium evaporative burner and a method of using the same. Background technique [0002] As the core component of the combustion heater, the burner has a significant impact on the fuel combustion efficiency. Therefore, improving the fuel combustion efficiency is an important method to improve the efficiency of the combustion heater. The evaporation of fuel oil and the quality of combustion have a significant impact on the thermal efficiency and pollution emissions of the heater. Traditional evaporative burners are mostly simple cylindrical burners, which often have excessively high pollution emissions in practice. Porous medium evaporative combustion can effectively improve combustion efficiency and reduce environmental pollution. At the same time, its own design structure can reduce the flow dead zone, and it is not easy to generate c...
