摘要

PROBLEM TO BE SOLVED: To provide a premix combustor having multiple premix times providing stable combustion in order to solve the problem of combustion driven fluctuations negatively impacting the life of gas turbine components, which may result in more frequent outages and declines of turbine power output.SOLUTION: A combustor 11 having a combustion chamber 20 is provided with an external flow sleeve 17 and a combustor liner 19 surrounding the combustion chamber 20. A plurality of flow channels 56 are provided on the combustor liner 19 and a plurality of nozzles 45 are disposed at predetermined locations on the flow channels 56. The locations of the nozzles 45 are selected to provide different mixing times for fuel 49 injected through the nozzles 45.
