TURBINE COMBUSTOR SYSTEM HAVING AERODYNAMIC FEED CAP

摘要

PROBLEM TO BE SOLVED: To provide a system configured to reduce a state having a low flow or having no flow in a head end of a turbine combustor.SOLUTION: A system having a turbine combustor is provided. The turbine combustor includes a fuel nozzle having an inner shell and an outer shell and a feed cap disposed around the fuel nozzle and having an outer wall and a back plate. The back plate joins respective upstream ends of the outer shell of the fuel nozzle and the outer wall of the feed cap. The turbine combustor is configured to cause a first pressurized air to flow along the outer wall of the feed cap along a back plate of the feed cap and via an air path extended into the fuel nozzle.
