Zusammenfassung:	A system for directing cooling air into a gas turbine combustor is provided. The system comprises a transition duct coupled to a flow sleeve, where air to be used for combustor cooling and in the combustion process enters a bellmouth of the transition duct, passes through a plurality of struts within the bellmouth, and is distributed to a passage located between the combustion liner and flow sleeve. 提供了一种用于将冷却空气引导到燃气涡轮机燃烧室中的系统。该系统包括耦接至流动套筒的过渡管道，其中，待用于燃烧室冷却并在燃烧过程中使用的空气进入过渡管道的喇叭口，穿过喇叭口内的多个支柱，并且分配到位于燃烧衬套与流动套筒之间的通道。
