Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a novel burner. Background Technology

[0002] Currently, heat treatment primarily utilizes the heat generated by the combustion of combustible gas within a heat treatment furnace to alter the temperature of metal materials placed inside, thereby changing their shape or properties. Most furnaces employ direct-injection burners for calcination and heating. However, in actual production, common drawbacks have been observed: firstly, fuel and air are not completely and adequately mixed, resulting in incomplete combustion; secondly, once the furnace temperature reaches a certain level, it cannot rise further, leading to inefficient use of fuel within the burners and resulting in waste.
