Abstract
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.
Claims20
A method for assembling an injection device for use in a reactor injector feed assembly, said method comprising:
- coupling at least two annular reactant conduits defined within an injector body in fluid communication with at least two corresponding annular reactant nozzles defined within a tip oriented on an end of the injector body;
- coupling a cooling fluid supply plenum to the injector body;
- coupling a cooling fluid return plenum to the injector body;
- and
- coupling at least two cooling channels in fluid communication with the cooling fluid supply plenum and the cooling fluid return plenum, wherein at least a first of the cooling channels is oriented radially outwardly of at least one annular reactant nozzle and at least a second of the cooling channels is oriented radially inwardly of the at least one annular reactant nozzle;
- wherein said second of the cooling channels comprises a plurality of radially inner cooling channels.
A gasification facility comprising:
- at least one carbonaceous reactant source;
- at least one oxygenated fluid reactant source;
- at least one gasification reactor comprising at least one injection device coupled in flow communication with said at least one carbonaceous reactant source and said at least one oxygenated fluid reactant source, said at least one injection device comprising:
- an injector body having at least two annular reactant conduits defined therein;
- a tip oriented on an end of said injector body and having at least two annular reactant nozzles defined therein, wherein said each of said at least two annular reactant nozzles is coupled in fluid communication with a respective one of said at least two annular reactant conduits;
- a cooling fluid supply plenum coupled to said injector body;
- a cooling fluid return plenum coupled to said injector body;
- and
- at least two cooling channels coupled in fluid communication with said cooling fluid supply plenum and said cooling fluid return plenum, wherein at least a first of said cooling channels is oriented radially outwardly of at least one annular reactant nozzle and at least a second of said cooling channels is oriented radially inwardly of said at least one annular reactant nozzle;
- wherein said second of the cooling channels comprises a plurality of radially inner cooling channels.
An injection device for use in a reactor injector feed assembly comprising:
