Abstract: Embodiments of hot streak alignment for gas turbine durability include structures and methods to align hot streaks with the leading edges of aligned first stage nozzle vanes in order to improve mixing of the hot streaks with cooling air at a stator nozzle of a first stage turbine and reduce usage of cooling air at first stage non-aligned stator nozzle vanes disposed adjacent to the aligned stator vanes.

Abstract: The present disclosure is directed to a method of operating a combustion system to attenuate combustion dynamics. The method includes flowing, via a compressor section, an overall supply of air to the combustion system; flowing, via a fuel supply system, an overall flow of fuel to the combustion system; flowing, to a first fuel nozzle of the combustion system, a first supply of fuel defining a richer burning fuel-air mixture at the first fuel nozzle; flowing, to a second fuel nozzle of the combustion system, a second supply of fuel defining a leaner burning fuel-air mixture at the second fuel nozzle; and igniting the richer burning fuel-air mixture and the leaner burning fuel-air mixture to produce an overall fuel-air ratio at a combustion chamber of the combustion system.

Abstract: The present subject matter provides a combustion system which comprising: a cowl; a deflector configurated to include a ring body, a plurality of swirlers integrated on the ring body and a plurality of arms integrally extending outward from the ring body; an annular inner liner attached with the cowl; and an annular outer liner attached with the cowl. The deflector is positioned between the inner liner and the outer liner; the deflector, the inner liner and the outer line define a combustion chamber thereamong. The deflector is attached to the cowl via the plurality of arms, but the arms are rigid enough to work together to fix the deflector with the cowl while allowing for thermal expansion flexibility therebetween at the same time.

Abstract: A combustor includes an outer liner, an inner liner, an annular cowl joining upstream ends of the outer and inner liners, and an annular deflector configured to shield the cowl from hot combustion gases in a combustion chamber defined between the outer liner, the inner liner and the deflector. The cowl has at least one opening for introduction of fuel and compressed air. The deflector includes at least one swirler. The cowl defines at least one axial cowl hole, and the deflector defines at least one corresponding axial deflector hole, wherein the corresponding deflector hole and cowl hole are configured to receive a fastener for fastening together the cowl and the deflector.

Abstract: A system of integrating baffles for enhanced cooling of CMC liners is comprised of a combustor assembly having a dome mount assembly, outer liner and inner liner. Liners include those manufactured from and in a process for CMC (Ceramic Matrix Composite). One or more liner baffles such as outer baffle and inner baffle, are provided to reduce the pressure drop across the liner, allowing the addition of more cooling holes and thereby reducing the cooling hole spacing while not increasing the required amount of cooling air. CMC liners are incorporated, as desired, to take advantage of shapes and hole dispositions made possible by use of CMC over past designs.
