Combustion chamber e.g. gas turbine-combustion chamber, has notches formed at tips on side of base surfaces of main nozzles by providing slot having different level to position corresponding to intermediate position between nozzles

摘要

The chamber has an external cylinder (2c) provided at a side of an outside circumference of a combustion chamber-casing (2a) and cylinders (53). The external cylinder serves as a passageway of compressed air between an inner wall and an outside wall of the combustion chamber-casing and the cylinders. Notches are formed at tips on a side of base surfaces of main nozzles (22) of the cylinders by providing a slot having a different level to a position corresponding to an intermediate position between the two adjacent main nozzles.
