Abstract: A fuel injector assembly for a gas turbine engine is generally provided. The first fuel injector includes a first centerbody surrounding a first walled fuel injection circuit. A first fuel injection port is extended at least partially radially through the first centerbody in fluid communication with the first walled fuel injection circuit. The first centerbody defines a cooling circuit surrounding the first walled fuel injection circuit. The first centerbody defines a plurality of cooling openings at a downstream end of the first centerbody. The plurality of cooling openings is in fluid communication with the cooling circuit. The first centerbody defines an axially extended cooling outlet at the downstream end of the first centerbody.

Abstract: The present disclosure is directed to a combustion section for a gas turbine engine. The combustion section includes a combustor assembly, an outer casing, a fuel injector assembly, and an inner casing. The combustor assembly includes an inner liner and an outer liner each extended at least partially along a lengthwise direction and at an acute angle relative to the longitudinal centerline. The combustor assembly further includes a dome assembly extended between the inner liner and the outer liner. The dome assembly, the inner liner, and the outer liner together define a combustion chamber therebetween. The combustor assembly still further includes a bulkhead assembly defining a plurality of walls coupled to the inner liner and generally surrounding the outer liner and dome assembly. At least a portion of the bulkhead assembly is extended at least partially along a forward direction and defines a plenum between the bulkhead assembly and the dome assembly. The outer casing surrounds the combustor assembly and is extended at least partially co-directional to the combustor assembly. The fuel injector assembly is extended through the outer casing, the bulkhead assembly, and the dome assembly. The inner casing, the outer casing, and the combustor assembly together define a primary flowpath in direct fluid communication with the combustion chamber. The primary flowpath is extended at least along a forward direction and an aft direction defined by inner casing, the outer casing, and the combustor assembly. An oxidizer flows through the primary flowpath in serial flow through the plenum and the fuel injector assembly into the combustion chamber.

Abstract: The present application provides a gasifier for creating a flow of a syngas. The gasifier may include a reaction chamber and a quench chamber. The quench chamber may include a number of integrated scrubber trays therein such that the syngas first enters a quench pool via a dip tube and then passes through the scrubber trays before leaving the quench chamber.
