System and method for supplying a working fluid to a combustor

摘要

A system for supplying a working fluid to a combustor (16) includes a fuel nozzle and a combustion chamber (40) downstream from the fuel nozzle. A flow sleeve (50) circumferentially surrounds the combustion chamber (40), and a plurality of fuel injectors (60) are circumferentially arranged around the flow sleeve (50) to provide fluid communication through the flow sleeve (50) to the combustion chamber (40). A distribution manifold (62) circumferentially surrounds the plurality of fuel injectors (60), and a fluid passage (66) through the distribution manifold (62) provides fluid communication through the distribution manifold (62) to the plurality of fuel injectors (60). A method for supplying a working fluid (24) to a combustor (16) includes flowing a working fluid from a compressor through a combustion chamber (40) and diverting a portion of the working fluid through a distribution manifold (62) that circumferentially surrounds a plurality of fuel injectors (60) circumferentially arranged around the combustion chamber (40).
