Abstract
PURPOSE: To improve the efficiency of cooling a liner of a combustion device for gas turbines, which liner is doubly formed with respect to a part or the whole of its length, by providing the liner with an inwardly bent head portion of a predetermined curvature.
CONSTITUTION: In a combustion decice 1 for a gas turbine, compressed air 100 from an air compressor 5 is emitted between a high-temperature duct, i.e. a transition piece 4, which communicates a liner 2 with a turbine nozzle 6, and a turbine casing 11 so as to flow backwardly to a head portion of the combustion device 1. This air is supplied into the combustion device for combustion and cooling purposes. The head portion of the liner 2 has two walls 12, 13 the end sections 14 of which are bent inwardly in the liner 2 at a predetermined curvature. Those parts of the end sections 14 which are on the upstream side thereof define slits 15 for passing cooling air therethrough. Namely, a part of air 106 for combustion flows into the liner as cooling air 107 through the slits 15.
