RICH LEAN COMBUSTION APPARATUS

摘要

The rich lean combustion apparatus according to the present invention comprises: a first plate and a second plate which are provided to face each other, and between which a rich mixer flow path is provided so that a rich mixer flows through the rich mixer flow path; a third plate which is provided so that a lean mixer flows through a lean mixer flow path which is formed between the second plate and the third plate; a first burner port member for combusting the rich mixer; and a second burner port member for combusting the lean mixer, wherein the rich mixer flow path comprises a plurality of first rich mixer flow paths which are disposed in the upper portion of a distribution hole to be spaced apart from one another by a predetermined distance, and a second rich mixer flow path which is formed between the first rich mixer flow path and the first burner port member; a blocking unit is provided on both sides of the first rich mixer flow path to block the flow of the mixer; and a blocking protrusion unit is formed in the blocking unit by transforming a part of the first plate and the second plate, which have a plane shape.
