Abstract: A late lean injection (LLI) manifold is provided and includes a central nozzle and first and second side nozzles positioned at circumferential locations defined around a vessel, a connector, a first leg, to which the connector is connected, formed to define a tube extending from the central nozzle to the first side nozzle such that fuel is communicable between the connector, the central nozzle and the first side nozzle and a second leg. The second leg is formed to define a tube extending from the central nozzle to the second side nozzle such that the fuel is communicable between the central nozzle and the second side nozzle.

Abstract: A gas turbine transition piece adapted to carry combustion gases in a hot gas path extending between a gas turbine combustion chamber and a first stage of the gas turbine, includes a hollow duct having a forward end adapted for connection to a combustor liner and an aft end adapted for connection to a first stage nozzle. One or more dilution air holes are located proximate the forward end, the dilution holes each fitted with a hollow sleeve penetrating into the hot gas path within the hollow duct, the hollow sleeves adapted to supply cooling air into the hot gas path.
