CA 2608869

A combustor heat shield has a body defining a fuel nozzle hole. The back face of the body is mounted adjacent and spaced-apart from a combustor dome. A ridge extends around the nozzle opening to a height adapted to substantially contact the combustor dome. The ridge thereby defines a cooling compartment between the body and the combustor dome. A plurality of slots is provided through the ridge. The slots are closed by the combustor dome to provide cooling holes when the heat shield is mounted on the combustor. The cooling holes direct pressurized cooling air from the compartment to adjacent regions of the back face of the heat shield body.
