Beschreibung
Zusammenfassung:	Abstract A thermal machine, especially a gas turbine, comprises an annular combustor which is outwardly delimited by an outer shell and an inner shell (33) and through which a hot gas flow flows in the axial direction, wherein the outer shell and inner shell (33) are provided in each case with a concentric cooling shroud (31) which is attached at a distance on their outer side, forming a cooling passage (32) through which cooling passage (32) cooling air flows in a direction which is opposite to the hot gas flow. With such a machine, the cooling of the combustor is improved by at least one of the cooling shrouds (31), on the side on which the cooling air enters the cooling passage (32), having an outwardly curved, rounded inlet edge (37) for improving the inflow conditions.
