Abstract: A combustor for providing homogeneous combustion of liquid fuels includes an essentially tube shaped combustion body, including a combustion chamber having a plurality of reaction zones, one of which is an injection zone, the others being combustion zones for staged homogeneous combustion of evaporated fuel and air. A swirler, including a base and swirler elements, is configured to operate at a swirl number between 0.6-2.5 in combination with a flow constriction plate whose size is such that the ratio of the open diameter (De) of the constriction to the diameter (D) of the combustion body is <0.7 and the constrictor plate is placed at a distance (L1) from the base of the swirler base so that L1/De>1. A primary mixing plate is placed downstream from the constriction plate at a distance (L2) so that the ratio L2/L1<1 to allow maximum mixing of the homogeneous combustion.
