Abstract
A turbomachine includes a compressor, a combustor operatively connected to the compressor, and an injection nozzle operatively connected to the combustor. The injection nozzle includes a main body having a first end section that extends to a second end section to define an inner flow path. The injection nozzle further includes an outlet arranged at the second end section of the main body, at least one passage that extends within the main body and is fluidly connected to the outlet, and at least one conduit extending between the inner flow path and the at least one passage.
Claims9
A turbomachine comprising:
- a compressor;
- a combustor operatively connected to the compressor;
- and
- an injection nozzle operatively connected to the combustor, the injection nozzle including:
- a main body having a first end section that extends to a second end section defining an inner flow path;
- an outlet arranged at the second end section of the main body;
- a plurality of passages extending within the main body at the second end and being fluidly connected to the outlet;
- a plenum arranged within the main body at the second end, the plenum being fluidly connected with the plurality of passages;
- a first plurality of conduits extending between and fluidly connected with the inner flow path and the plenum;
- and
- a second plurality of conduits extending between the plenum and the plurality of passages.
A method of introducing a combustible mixture into a turbomachine combustor, the method comprising:
- introducing a first fluid into an inner flow path of an injection nozzle, the injection nozzle including a first end section that extends to a second end section defining a main body, the main body including an outlet arranged at the second end section;
- passing a second fluid into a plurality of passages extending substantially radially through the main body at the second end;
- guiding the first fluid from the inner flow path through a plurality of conduits into a plenum arranged in the main body at the second end;
- passing the first fluid from the plenum into the plurality of passages to mix with the second fluid to form a combustible mixture;
- and
- discharging the combustible mixture through the outlet into the turbomachine combustor.
