ABSTRACT:
Combustion apparatus for a gas turbine engine comprises a burner which is so configured and located within a combustion chamber so as to urge fuel and air mixture ejected therefrom into a fuel rich toroidal vortex in an upstream first combustion zone of the combustion chamber. Unburnt fuel from the first combustion zone is mixed with additional air in a second fuel weak combustion zone downstream of the first zone. Adjustment of the air to fuel ratios in the two combustion zones results in the reduction of smoke and oxides of nitrogen reduction.
