Abstract
A shroud structure and a combustor burner using the shroud structure are provided for improving swozzle flow. The shroud structure includes a shroud configured to surround a combustion nozzle and a plurality of swirlers provided along a circumferential row of the combustion nozzle, the shroud having an outer circumferential surface in which a plurality of inlets are formed to draw in compressed air flowing outside the shroud, the compressed air being drawn into the shroud before being mixed with fuel. The inlets are disposed, at positions spaced apart from each other, before a circumferential row of the outer circumferential surface of the shroud that faces a first fuel injector provided on an inner circumferential surface of a combustor casing so that compressed air guided into the inlet is supplied to a region formed around a second fuel injector provided in the swirlers in the shroud.
