ABSTRACT:
A surface burner which combusts a gas and oxygen mixture uses a tri-laminar delivery of the oxygen and fuel gas to the burner face with individual control over the flow of each gas. The structure of the laminar flow at the burner face includes an oxygen jet at the center, a surrounding fuel gas jet, and a third jet means for the delivery of an oxygen flow which surrounds the flow of the other gases. Each of the three flows is individually adjustable so that the most efficient combination of combustion gases is selected to achieve the desired resultant flame characteristics. The body of the burner is cooled by a circumferential oxygen delivery chamber which is bounded by the inside surface of the outer wall of the burner body. The internal structure of the burner includes separate gas delivery chambers constructed by using stacked chamber-separated plates spaced apart and positioned within the cylindrical burner body. Individual tubing carries the gases between the individual chambers and the burner face.
