A combustor () includes a cap (), a liner (), a transition piece (), and a combustion chamber () located downstream from the cap () and defined by the cap and liner. A secondary nozzle () circumferentially arranged around the liner () or transition piece () includes a center body, a fluid passage through the center body, a shroud circumferentially surrounding the center body, and an annular passage between the center body and the shroud. A method for supplying fuel to a combustor () includes flowing fuel through a primary nozzle radially disposed in a breech end of the combustor and flowing fuel through a secondary nozzle () circumferentially arranged around and passing through at least one of a liner () or a transition piece. The secondary nozzle () includes a center body, a fluid passage through the center body, a shroud circumferentially surrounding at least a portion of the center body (), and an annular passage between the center body and the shroud.

Combustor and method for supplying fuel to a combustor

A transition duct for a combustor of a gas turbine generally includes a transition duct having a frame at an aft end of the transition duct. The frame generally includes a downstream end, a radially outer portion, a radially inner portion opposed to the radially outer portion, a first side portion between the radially outer and inner portions, and a second side portion opposed to the first side portion. A slot in the first side portion of the frame may have a downstream surface adjacent to the downstream end of the frame. A heat shield having an inner surface, an outer surface and a plurality of spacers may extend generally outward from the heat shield inner surface such that the inner surface is adjacent to the slot downstream surface and the frame downstream end.
