ABSTRACT:
A combustion chamber10for a gas turbine that operates in a highly diluted mode of combustion has a substantially toroidal plenum30. At least one combustion fluid injector is located at the periphery of the plenum. The shape of the plenum and the disposition of the combustion fuel injectors are such that a vortex flow2is established in the combustion chamber in use. Gasses are entrained in the vortex which provides high enough levels of flue gas re-circulation to allow for the onset of highly diluted combustion.
