A gas power burner having a burner tube closed at one end and a venturi tube 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 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 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 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.

Small gas power burner

A food preparation apparatus including a cooking chamber having a pair of openings in two opposite facing walls thereof. A conveyor extends through the side wall openings in the chamber for conveying a food product through the chamber. First and second pairs of impingement finger ducts are provided for forming a plurality of columnated air jets and for impinging the jets against discreet points of a food product supported on the conveyor. A first one of each of said pairs of finger ducts is disposed above the conveyor and a second one of each of said pairs of finger ducts is disposed below the conveyor. First and second plenums, each of which has a fan respectively associated therewith, supply air to the finger ducts. A single burner is associated with the plenums for simultaneously supplying thermal energy to both plenums. The burner includes a first adjustable baffle for apportioning the thermal energy between the two plenums. The burner includes a second baffle located in the return air stream forwardly of the burner flame to generate a negative pressure zone and draw the flame forwardly, away from the back wall of the burner.
