    Abstract: A secondary fuel nozzle for a turbine includes a passive purge air passageway which provides purge air to the secondary nozzle at all times that the nozzle is in operation. The passive purge air passageway draws in air from a location adjacent an upstream end of the nozzle. Because of a pressure differential between air located at the downstream end of the nozzle and air located at the upstream end of the nozzle, purge air will run through the passive purge air passageway at all times the nozzle is in operation. There is no need for a supply of compressed purge air.

    Abstract: A liner (18) installed in a transition region (16) between a combustion section (12) of a gas turbine engine (10) and an air discharge section (14) of the turbine. The liner has an air inlet (26) for admitting air into the liner, and an air outlet (28) by which air is discharged from the liner. Flow of air through the liner acts to cool air flowing through the transition region of the turbine between the combustion and air discharge sections thereof, so to lower the temperature from between 2800-3000° F. to around 1400-1550° F. The liner has at least one channel (C1, C2) formed in it for flow of air through the liner. The height of this channel uniformly decreases along the length of the channel from the liner's air inlet to its air outlet. This liner construction reduces the thermal strain occurring at the aft end of the liner, prolonging the useful life of the liner, while reducing the amount of air needed to flow through the liner to affect a desired level of cooling in the transition region.
