Abstract
A combustor includes a fuel injector to inject fuel; a cooling passage configured to pass compressed air for cooling an outer surface of a liner forming a combustion chamber for containing combustion gas; and a nozzle part that is coupled to the liner and has a rear surface facing the combustion chamber, the nozzle part configured to mix the compressed air with the fuel from the fuel injector and to discharge some of the compressed air in the cooling passage to the rear surface in order to block an introduction of the combustion gas into the nozzle part. Before the compressed air introduced through air introduction holes formed in a nozzle casing is discharged through through-holes formed in a nozzle cap, some of the compressed air may be introduced through bypass holes formed in a bypass tube and then discharged to the combustion chamber through the gap.
