Abstract
In order to cool the hot surface of the heat shield that surrounds the burner of a gas turbine annular combustion chamber as efficiently as possible, especially in the vicinity of the burner throughflow opening, a cooling air stream that escapes through a ridge that runs around the edge of the throughflow opening is guided by a guide rib in the direction of the throughflow opening. This guide rib is aligned essentially parallel to the ridge and on the combustion chamber side has an end that is bent in such fashion that the cooling air stream that flows into the gap between the ridge and the guide rib is deflected thereby in the direction of the hot surface of the heat shield.
