    Abstract: A method of assembling a radiant cooler includes providing a vessel shell that defines a gas flow passage therein that extends generally axially through the vessel shell, forming a tube cage from coupling a plurality of cooling tubes together to form a tube cage defined by a plurality of chevron-shaped projections that extend circumferentially about a center axis of the tube cage, each chevron-shaped projection includes a first side and a second side coupled together a tip, circumferentially-adjacent pairs of projections coupled together such that a valley is defined between each pair of circumferentially-spaced projections, each of the projection tips is positioned radially outward from each of the valleys, and orienting the tube cage within the vessel shell such that the tube cage is in flow communication with the flow passage.

    Abstract: A combustor for a gas turbine includes a main fuel injector for receiving compressor discharge air and mixing the air with fuel for flow to a downstream catalytic section. The main fuel injector includes an array of venturis each having an inlet, a throat and a diffuser. A main fuel supply plenum between forward and aft plates supplies fuel to secondary annular plenums having openings for supplying fuel into the inlets of the venturis upstream of the throats. Each diffuser transitions from a circular cross-section at the throat to multiple discrete angularly related side walls at the diffuser exit. Gaps between circumferentially and radially spaced diffusers at their exits are eliminated. With this arrangement, uniform flow distribution of the fuel/air, velocity and temperature is provided at the catalyst inlet.

    Abstract: A bypass air injection scheme for a combustor of a gas turbine. Combustor includes a body with an inner liner and a casing enclosing the body with a passageway defined therebetween. A predetermined amount of the compressor discharge air passing through the passageway is extracted through a manifold. A conduit feeds the extracted air into an injection manifold having a plurality of injection tubes for injecting the extracted air into the combustor bypassing the reactor. The injection tubes and the injection manifold are disposed in a substantially common axial plane.
