Abstract: A burner head is constructed with adjacent gas delivery tubes of different geometric cross-section shapes which are mechanically held in place radially. The tubes touch in a longitudinal direction at points along their respective inner and outer circumferences so that precise axial alignment whether coaxial or axially offset, is achieved while preserving the necessary laminar gas flow. This configuration greatly speeds the production time which allows economical burners to be produced even when a greater number of faceplate jets is desired. The tube-to-tube contact is also beneficial to the operation of the burner by providing a heat transfer path away from the innermost tube, which prevents overheating. Examples of the simplest geometric tube shapes employed are, for example, a square within a circle, or conversely, a circle within a square.

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.
