Patent ID: 8721747

Claim:
An injection device comprising: a plurality of substantially concentric annular conduits oriented in a reactor injector feed assembly, said plurality of substantially concentric annular conduits including at least a first annular conduit and a substantially concentric second annular conduit, said first annular conduit and said second annular conduit define an injection device centerline therein, wherein said plurality of substantially concentric annular conduits is defined by at least three radially separated annular conduit walls, and wherein each of said first and second annular conduits is defined by a pair of said radially separated annular conduit walls; and said reactor injector feed assembly further including a modular tip releasably coupled to said plurality of substantially concentric annular conduits, wherein said modular tip includes: a first substantially annular nozzle substantially aligned with and coupled directly to said first annular conduit; and a second substantially annular nozzle substantially aligned with and coupled directly to said second annular conduit, wherein said modular tip includes at least three radially separated annular nozzle walls, and wherein each of the first and second annular nozzles is defined by a pair of said radially separated annular nozzle walls, such that the annular conduit walls of the first and second conduits are substantially aligned with respective annular nozzle walls of the first and second annular nozzles.
