Abstract (en)

An industrial turbine engine comprises a combustion section, an air discharge section downstream of the combustion section, a transition region between the combustion and air discharge section, a combustion transition piece (120) and a sleeve (129). The transition piece (120) defines an interior space (304) for combusted gas flow. The sleeve (129) surrounds the combustor transition piece (120) so as to form a flow annulus (124) between the sleeve (129) and the transition piece (120). The sleeve (129) includes a first set of apertures (400) for directing cooling air (I) from compressor discharge air into the flow annulus (124). The transition piece (120) includes an outer surface (300a) bounding the flow annulus (124) and an inner surface (300b) bounding the interior surface (304), and includes a second set of apertures (200) for directing cooling air in the flow annulus (124) to the interior space (304). Each of the second set of apertures (200) extends from an entry portion (200a) on the outer surface (300a) to an exit portion (200b) on the inner surface (300b).
