COMBUSTOR ASSEMBLY HAVING FUEL PRE-MIXER

摘要

PROBLEM TO BE SOLVED: To provide a combustor assembly having a fuel pre-mixer including a duct for mixing an airflow and a fuel therein.SOLUTION: Also included is a center body 38 coaxially aligned within a duct 28 for receiving a fuel from a fuel source and configured to distribute the fuel to at least one axial location within the duct. Further included is a planar vane section 40 in communication with an airflow 24 and the fuel to provide a first injection of fuel and a flow conditioning effect on the airflow 24. Yet further included is a swirler vane section 42 disposed downstream of the planar vane section 40, wherein the swirler vane 42 section is configured to provide a second injection of fuel and a mixing of the fuel and the airflow 24.
