Abstract

The tube (22), which directs combustion air to the primary zone of a gas turbine combustion chamber, has a stepped configuration defined by a shortened wall (40) spaced outwardly from the downstream facing wall (38) of the main air inlet tube (34) to provide a slot (36) for directing a layer of air over the inwardly projecting downstream wall of the tube to protect this portion and the vulnerable downstream edge of the tube from contact with the hot gases in the combustion chamber. <IMAGE>
