PROBLEM TO BE SOLVED: To provide a turbo-machine including a plurality of injection nozzles (37, 38) arranged in an annular cylindrical array (40) and a transition piece (55) including at least one wall (64) defining a combustion flow passage (72). SOLUTION: A dilution orifice (67) is formed within the 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 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) and dilution passages (140-142) extended through the body (135). The dilution passage (140-142) is shifted from the dilution orifice (67). The heat shield member (80) is spaced from the wall (64) of the transition piece (55) and defining a flow region (100) between the one wall (64) and the second surface.
