Document Type and Number:
Japanese Patent JP2015206584
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel nozzle shroud and a method of manufacturing the shroud.SOLUTION: A fuel nozzle includes a center body that is at least partially surrounded by an outer shroud. The outer shroud is radially spaced from the center body to define a pre-mix flow passage between the center body and the outer shroud. The outer shroud includes a main body that defines an inner side portion, an outer side portion and a forward end portion that is axially separated from an aft end portion. The main body further defines a cooling channel that is fully circumscribed between the inner side portion and the outer side portion and that extends at least partially between the forward end portion and the aft end portion. The main body also defines a cooling air inlet that is in fluid communication with the cooling channel and a cooling air outlet that is in fluid communication with the cooling channel downstream from the cooling air inlet.
