FIELD: heating.
SUBSTANCE: heat shield for the combustion chamber of a gas turbine contains a carrying structure and a plurality of bricks fixed dismountable on the carrying structure by means of holders. Each brick of the heat shield has a cold side facing the carrying structure and a hot side opposite it. Each brick holder comprises of at least one supporting portion for fixing a heat shield to the brick and one fixing portion on the carrying structure fixed dismountable within the mounting slots running in the carrying structure. To protect against hot gases in the carrying structure, at least one cooling air passage is provided. It extends down to the bottom of the mounting slot.
EFFECT: invention makes it possible to cool the heat shield down and to prevent scaling of the carrying structure.
