<p>It is described a combustion arrangement (100), comprising: a casing (101); a combustion chamber (103) arranged within the casing (101), wherein an inner casing volume (107, 109) is defined to be a volume inside the casing but outside the combustion chamber; a partitioning wall (105) partitioning the inner casing volume into a first volume portion (107) and a second volume portion (109), the partitioning wall having at least one aperture (111, 113) to allow fluid communication (145) between the first volume portion (107) and the second volume portion (109); and a valve (115) arranged at the casing to allow an outgoing fluid flow (116) from the inner casing volume (107, 109) to an outside (119) of the casing (101) depending on a valve operating position; wherein the combustion chamber has a combustion entry port (121) for supplying an oxidant into the combustion chamber (103), wherein the combustion entry port (121) is in fluid communication with the first volume portion (107), wherein the arrangement (100, 125) is adapted to adjust the valve operating position for damping an oscillation of the arrangement.</p> |
