COMBUSTION CHAMBER HOUSING AND GAS TURBINE EQUIPPED THEREWITH

摘要

Combustion chamber housing (10) and gas turbine (1) outfitted therewith. The combustion chamber housing has a flame tube (20) and a casing tube (30) which surrounds the flame tube and which has a plurality of openings (31) in its wall through which air outwardly streaming upon the casing tube can penetrate radially into an intermediate space (40) formed between the casing tube and flame tube. The invention ensures a more uniform distribution of the in-flowing air around the flame tube. This is achieved inter alia in that a plurality of guide ribs (50) are provided which are arranged in the intermediate space so as to be distributed around the circumference of the two tubes and which extend in each instance radially between the casing tube and flame tube and parallel to a longitudinal direction (LR) of the two tubes so that the intermediate space is divided by the guide ribs into a plurality of longitudinal channels (41).
