Patent ID: 8745987

Claim:
Multiple late lean injection (LLI) manifolds for a gas turbine engine comprising multiple combustors and multiple transition pieces respectively disposed downstream from corresponding ones of the multiple combustors, each of the multiple LLI manifolds comprising: a central nozzle and first and second side nozzles positioned at circumferential locations defined around a downstream portion of a corresponding one of the multiple combustors or transition pieces; a connector receptive of fuel for the corresponding one of the multiple LLI manifolds from a penetration component fluidly connecting two adjacent LLI manifolds of the multiple LLI manifolds; and a first leg to which the connector is connected and a second leg formed to define tubes extending from the central nozzle to the first and second side nozzles, respectively, such that fuel is communicable between the connector, the central nozzle and the first and second side nozzles.
