A method of assembling an injection device for use in a reactor injector feed assembly includes extending the injection device at least partially into a cavity. The injection device includes a plurality of substantially concentric conduits coupled to a modular tip that includes a plurality of cooling channels and a plurality of substantially annular nozzles defined therein. The method also includes coupling at least one coolant distribution device in flow communication with the plurality of cooling channels to facilitate removing heat from an outer surface of the injection device.

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.

A method of producing a synthetic gas (syngas) includes injecting a plurality of reactant streams into a gasification reactor via at least one injection device having a plurality of injection annuli, an inner portion that extends annularly about a centerline extending through the at least one injection device, and an outer portion extending substantially annularly about the inner portion. At least a portion of the outer portion is oriented obliquely with respect to the at least one injection device centerline. The method also includes mixing at least a portion of each of the streams together such that a plurality of recirculation zones is defined by the streams. The method further includes producing a syngas within the recirculation zones via mixing at least a portion of each of the streams. The injection device includes an inner portion that extends annularly about a centerline extending through the injection device. The device also includes an outer portion extending substantially annularly about the inner portion that includes at least one of at least one carbonaceous reactant injection port oriented obliquely with respect to the injection device centerline and at least one outer face oriented obliquely with respect to the injection device centerline.
