Abstract
Official abstract text for this publication.
A combustion device ( 1 ) for a gas turbine includes portions ( 12 ) having an inner and an outer wall ( 13, 14 ) with an interposed noise absorption plate ( 15 ) having a plurality of holes ( 16 ). The combustion device ( 1 ) further has first passages ( 17 ) connecting zones between the inner wall ( 13 ) and the plate ( 15 ) to the inside of the combustion device ( 1 ) and second passages ( 21 ) for cooling the inner wall ( 13 ). The portions ( 12 ) also have an inner layer ( 22 ) between the inner wall ( 13 ) and the plate ( 15 ) defining inner chambers ( 23 ), each connected to at least a first passage ( 17 ), and an outer layer ( 24 ) between the outer wall ( 14 ) and the plate ( 15 ) defining outer chambers ( 25 ) connected to the inner chambers ( 23 ) via the holes ( 16 ) of the plate ( 15 ).
First claim
Opening claim text (preview).
We claim: 1. A combustion device for a gas turbine comprising: a portion having an inner wall and an outer wall and an interposed noise absorption plate having a plurality of holes between the inner wall and the plate, a plurality of zones being between the inner wall and the plate, the inner wall delimiting an inside of the combustion device; first passages connecting the zones between the inner wall and the plate to the inside of the combustion device; an inner layer between…
