US Patent 5803725: Triple-mix surface-mix burner
US 5803725 ยท granted 1998-09-08
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.

Claim 1
A gas burner, comprising: a hollow burner body, comprising side outer walls, a base plate at the bottom, and a burner face at the top; separate sources of individually regulated oxygen and a fuel gas in fluid communication with entrance ports located in said base plate, comprising: first valve means located on a first delivery line between said fuel gas source and a first entrance port for regulating the flow thereof; a manifold for dividing said oxygen source into two streams; second valve means located on a second delivery line carrying one of said two streams between said manifold and a second entrance port in said base plate; third valve means located on a third delivery line carrying the other of said two streams of oxygen between said manifold and a third entrance port in said base plate; means forming a first chamber within said body located directly above said base plate and in fluid communication with said second entrance port, said first chamber having exit ports including means in exclusive fluid communication with a firstgroup of ports in said burner face; means forming a second chamber directly above said first chamber including means in exclusive fluid communication w
