Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a side-inlet liquid fuel burner. Background Technology

[0002] Liquid fuel burners are combustion devices that use liquid fuels such as methanol as energy. They vaporize the liquid fuel and mix it with air for combustion. Therefore, their heat conversion efficiency is affected by the degree of mixing between fuel and air. Insufficient air intake will lead to uneven and incomplete combustion of fuel, resulting in waste and affecting use.

[0003] In practical use, it has been found that during long-term use, the air inlet of the burner is easily blocked by foreign objects, leading to incomplete mixing and combustion of air and fuel, thus reducing firepower. Therefore, existing liquid fuel burners still have issues that need improvement. Utility Model Content

[0030] A first air inlet 121 is provided to form a side air intake. The air distribution plate 2, made of steel or copper, is equipped with multiple air distribution holes 22. The side-entering air flows vertically upward through the air distribution holes 22, providing the air required for combustion to the burner cap 5. Steel or copper has a high melting point, so the air distribution holes 22 are not easily oxidized and blocked, and are highly durable.

[0031] Preferred, refer to Figure 4 The air distribution holes 22 are arranged in a ring array, and the top of the air distribution plate 2 is folded outward to form an edge 23, which overlaps the top of the cylindrical part 12.
