The invention refers to a combustion device comprising a wall arrangement having a first inner wall member (1) and a second wall member (7). The first wall member defines a combustion chamber (2) and is essentially continuous. The second wall member (7) is provided outside the first wall member and forms a space (8) between the first and second wall members. In order to cool down the combustion chamber, the second wall member comprises a great number of holes arranged to direct jets of a cooling fluid onto a main part of the outer surface of the first inner wall member (1). |
