SMALL GAS POWER BURNER

摘要

A gas power burner having a burner tube (16) closed at one end and a venturi tube (100) disposed within the burner tube with the mouth portion of the venturi tube disposed toward the closed end of the burner tube. The burner tube is provided with an air aperture (118) in a side thereof at a position along the burner tube intermediate the mouth portion and the burner head portion of the venturi tube. A blower (86) blows air into the air aperture of the burner tube where the air divides into a first pathway traveling toward the closed end of the burner tube and into the mouth of the venturi tube and also traveling in a second pathway toward the open end of the burner tube. The air traveling in the primary and secondary pathways provides combustion air for a flame burning at a burner head portion of the venturi located within the outer burner tube. A gas orifice (116) communicates combustible gas with the mouth portion of the venturi tube and meters and directs gas to the mouth portion for mixing with combustion air from the primary pathway.
