<p>A combustion chamber has a plurality of side chambers (10, 12, 14, 16) distributed about the central area of the chamber. A partition wall (28) divides the chamber into a first and a second chamber (32 and 34) and is extended by wall portions (28a) partly projecting into the side chambers and being attached to their side walls (12a, 12b) as well as leaving a through-flow opening (30) at the end edge (28b) of the respective wall portion (28a). The partition wall is provided with a plurality of stress concentration locations (36, 38, 40, 42) at which the partition wall ruptures into narrow cracks during the first few starts and heatings up to normal operational temperature and the coolings occurring during stopping, so that the partition wall will be free from stresses in subsequent operations of the apparatus. </p> |
