Patent ID: 7942006

Claim:
A combustion system, comprising: a combustor having a forward annular liner having a first plurality of effusion holes, and an aft annular liner having a second plurality of effusion holes and forming a combustion chamber with the forward annular liner, wherein the first plurality of effusion holes and the second plurality of effusion holes are adapted to receive compressed air from a compressor and contribute to a single toroidal recirculation air flow pattern in the combustion chamber; a rotary fuel slinger further adapted to receive a flow of fuel from a fuel source and to centrifuge the received fuel into the combustion chamber; and an igniter extending at least partially into the combustion chamber to ignite the fuel and compressed air in the combustion chamber, to thereby generate combusted gas, wherein the first plurality of effusion holes of the forward annular liner includes a first region of effusion holes, and the second plurality of effusion holes of the aft annular liner includes a second region of effusion holes, and wherein the effusion holes of the first region are oriented in a first direction and the effusion holes of the second region are oriented in a second direction, wherein the first direction is opposite from the second direction, wherein the aft annular liner further includes a first plurality of primary air holes downstream of the second region of effusion holes.
