A potted head combustion chamber is provided with an annular gap between the downstream end of the pot and the combustion chamber itself. Air is supplied radially inwardly through this gap to remove any fuel which adheres to the walls of the pot, and prevents it from reaching the walls of the combustion chamber. Fuel on the combustion chamber walls can cause localized burning of the fuel with a consequent increase in temperature of that part of the combustion chamber wall.
