Abstract
A combustor () for a gas turbine engine is provided comprising a primary combustion chamber () for combusting a first fuel to form a combustion flow stream () and a transition piece () located downstream from the primary combustion chamber (). The transition piece () comprises a plurality of injectors () located around a circumference of the transition piece () for injecting a second fuel into the combustion flow stream (). The injectors () are effective to create a radial temperature profile () at an exit () of the transition piece () having a reduced coefficient of variation relative to a radial temperature profile () at an inlet () of the transition piece (). Methods for controlling the temperature profile of a secondary injection are also provided.
