Abstract

A method of assembling an injection device for use in a reactor injector feed assembly includes coupling a plurality of substantially concentric conduits to a modular tip. The method also includes coupling a first conduit of the reactor injector feed assembly to a modular tip and coupling a second conduit of the reactor injector feed assembly to the modular tip. The modular tip includes a first substantially annular nozzle and a second substantially annular nozzle defined therein. The first conduit and the first substantially annular nozzle are centered about an injection device centerline.

Claims

1. 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.

2. An injection device for use in a reactor injector feed assembly in accordance with claim 1, wherein at least one of said first substantially annular nozzle and said second substantially annular nozzle are substantially divergent with respect to the injection device centerline.

3. An injection device for use in a reactor injector feed assembly in accordance with claim 2, wherein:

said first substantially annular nozzle is an inner gaseous oxygen (GOX) nozzle; and

said second substantially annular nozzle is a carbonaceous fuel nozzle.

4. An injection device for use in a reactor injector feed assembly in accordance with claim 3 further comprising:

a third conduit of the reactor injector feed assembly substantially concentric with said first conduit and said second conduit; and

a third substantially annular nozzle coupled to said third conduit, said third substantially annular nozzle is at least one of convergent, divergent, and parallel with respect to the injection device centerline.

5. An injection device for use in a reactor injector feed assembly in accordance with claim 4, wherein said third substantially annular nozzle is an outer GOX nozzle.

6. An injection device for use in a reactor injector feed assembly in accordance with claim 1, wherein at least one bayonet adapter is coupled to said modular tip.

7. An injection device for use in a reactor injector feed assembly in accordance with claim 6, wherein said at least one bayonet adapter is coupled to said modular tip via retention hardware.

8. An injection device for use in a reactor injector feed assembly in accordance with claim 7 further comprising a plurality of seals at least partially positioned within at least one of said at least one bayonet adapter and said modular tip.

9. An injection device for use in a reactor injector feed assembly in accordance with claim 1 further comprising:

an outer surface extending into a cavity such that said outer surface is exposed to a source of heat within the cavity;

a plurality of cooling channels defined within said injection device, each of said cooling channels is at least one of radially and axially inward of said outer surface; and

at least one coolant distribution device coupled in flow communication with said plurality of cooling channels to facilitate removing heat from at least a portion of said outer surface.

10. An injection device for use in a reactor injector feed assembly in accordance with claim 9, wherein:

said at least one coolant distribution device comprises at least one cooling channel orifice plate; and

said plurality of cooling channels comprises a plurality of substantially circumferential cooling channels comprising at least one of a plurality of radially outer cooling channels and a plurality of radially inner cooling channels.
