Combustor cap assembly

摘要

A system includes a multi-tube fuel nozzle assembly. The multi-tube fuel nozzle assembly includes a support structure defining an interior volume configured to receive an air flow. The combustor cap assembly also includes multiple mixing tubes disposed within the interior volume. Each mixing tube of the multiple mixing tubes is configured to mix air and fuel to form an air-fuel mixture. The multi-tube fuel nozzle assembly further includes a combustor cap coupled to the support structure. The combustor cap includes multiple furcating nozzles integrated within the combustor cap. Each furcating nozzle of the multiple furcating nozzles is coupled to a respective mixing tube of the multiple mixing tubes. Also, each furcating nozzle of the multiple furcating nozzles is configured to receive a flow of the air-fuel mixture and to partition the flow of the air-fuel mixture into multiple air-fuel mixture flows.
