Patent ID: 8685120

Claim:
An injection device comprising: a center face extending substantially perpendicularly to an axial centerline extending through said injection device; an inner portion that extends annularly about said center face, said inner portion comprising an inner conical face oriented at an obtuse angle relative to said axial centerline; and an outer portion extending substantially annularly about said inner portion, said outer portion comprising an outer conical face oriented at an obtuse angle relative to said axial centerline, said outer portion surrounding said inner portion and said center face; said outer portion comprising: at least one annular carbonaceous reactant injection port coupled to a source of carbonaceous material and oriented obliquely with respect to said injection device centerline; at least one first annular reactant injection port radially inward from said at least one annular carbonaceous injection port; at least one second annular reactant injection port radially outward from said at least one annular carbonaceous injection port, wherein the at least one first and second annular reactant injection ports are oriented obliquely with respect to the at least one annular carbonaceous reactant injection port; each of said at least one first and at least one second annular reactant injection ports coupled to a source of at least one of gaseous oxygen, air, oxygen-enriched air, steam, nitrogen, and carbon dioxide.
