Abstract
In an arrangement for sealing combustion-chamber bricks (8) which are force-cooled in a convective manner, the bricks (8) being arranged in at least two brick rows (6) in accordance with of an increasing combustion-space diameter and being put into supporting casings (7), and the cooling medium (12) flowing between brick (8) and supporting casing (7), and a gap (9) being present between the supporting casing (7) of the preceding brick row (6) and the respectively following brick row (6), which gap (9) is sealed by means of a seal (10), a plurality of springs (11) are firmly anchored to the supporting casing (7) in a distributed manner over the periphery, which springs (11) are connected to the seal (10) and press the seal (10) into the gap (9) between supporting casing (7) and brick (8) at least during the operation of the combustion chamber. The sealing effect is thereby increased without thermal stresses being introduced. The arrangement according to the invention is readily suitable for the conversion of existing combustion chambers, since it requires no alteration to the hitherto used bricks (8), the supporting casings (7) or seals (10).
