In one embodiment, a method for generating heat energy includes injecting a stream having a concentration of at least 50% oxygen (Ostream) into a primary gas stream through a mixer, the mixer discharging the Ostream as two or more spaced jets traversing the primary stream, thereby enriching the primary gas stream. The method further includes mixing fuel with the enriched primary gas stream, thereby forming a fuel stream; and combusting the fuel stream, thereby forming a flue gas stream.

Device and method for efficient mixing of two streams

Apparatus and methods for improved combustion of oxygen and a mixture of a non-gaseous fuel, which includes providing: 1) a source of a mixture of non-gaseous fuel and conveying gas; 2) a source of oxygen; 3) a burner operatively associated with a combustion chamber; 4) a fuel duct in fluid communication with the source of mixed non-gaseous fuel and conveying gas; 5) a tubular oxygen lance fluidly communicating with the source of oxygen; and 6) at least two injection elements in fluid communication with the source of oxygen. The fuel duct includes a portion that extends along an axis towards the burner. The lance is disposed along the axis and has a diameter D. The injection elements are configured to inject oxygen into, and mix therewith, a flow of the mixture upstream of, or at, the burner. At least one of the injection elements receives oxygen from the lance. The injection elements are spaced apart by a distance X, which is greater than the length of diameter D.
