<p>A turbomachine includes a plurality of injection nozzles (37, 38) arranged in a can-annular array (40) and a transition piece (55) including at least one wall (64) that defines a combustion flow passage (72). A dilution orifice (67) is formed in the at least one wall (64) of the transition piece (55). The dilution orifice (67) guides dilution gases to the combustion flow passage (72). A heat shield member (80) is mounted to the at least one wall (64) of the transition piece (55) in the combustion flow passage (72). The heat shield member (80) includes a body (135) having a first surface (136) and an opposing second surface (137) through which extends a dilution passage (140-142). The dilution passage (140-142) is off-set from the dilution orifice (67). The heat shield member (80) is spaced from the at least one wall (64) of the transition piece (55) defining a flow region (100) between the at least one wall (64) and the second surface</p> |
