Variable residence time vortex combustor
First Claim
1. A variable residence time vortex combustor comprising:
- a primary combustion chamber for containing a combustion vortex;
a plurality of louvres peripherally disposed about said primary combustion chamber and longitudinally distributed along its primary axis, said louvres inclined to impel air about said primary combustion chamber to cool its interior surfaces and to impel air inwardly to assist in driving the combustion vortex in a first rotational direction and to feed combustion in said primary combustion chamber;
a second combustion chamber including a secondary zone; and
said primary combustion chamber further including a narrowed waist region, interconnecting the output of said primary combustion chamber with said secondary zone for passing only lower density particles and trapping higher density particles in the combustion vortex in said primary combustion chamber for substantial combustion.

Abstract
A variable residence time vortex combustor including a primary combustion chamber for containing a combustion vortex, and a plurality of louvres peripherally disposed about the primary combustion chamber and longitudinally distributed along its primary axis. The louvres are inclined to impel air about the primary combustion chamber to cool its interior surfaces and to impel air inwardly to assist in driving the combustion vortex in a first rotational direction and to feed combustion in the primary combustion chamber. The vortex combustor also includes a second combustion chamber having a secondary zone and a narrowed waist region in the primary combustion chamber interconnecting the output of the primary combustion chamber with the secondary zone for passing only lower density particles and trapping higher density particles in the combustion vortex in the primary combustion chamber for substantial combustion.

17. A variable residence time vortex combustor comprising:
-
a primary combustion chamber for containing a combustion vortex and including a fuel injector, an air swirler for entraining fuel in air to form a fuel-air mixture deliverable to the combustion vortex, and an ignitor for igniting the fuel-air mixture; a plurality of louvres peripherally disposed about said primary combustion chamber and longitudinally distributed along its primary axis, said louvres inclined to impel air about said primary combustion chamber to cool its interior surfaces and to impel air inwardly to assist in driving the combustion vortex in a first rotational direction and to feed combustion in said primary combustion chamber; a second combustion chamber including a secondary zone having a plurality of apertures inclined to drive air about said second combustion chamber in a second rotational direction to cool its interior surfaces, to resist the continuance of the vortex beyond said waist region in the first rotational direction, and to assist in cooling combustion gases; and said primary combustion chamber further including a narrowed waist region, interconnecting the output of said primary combustion chamber with said secondary zone, for passing only lower density particles and trapping higher density particles in the combustion vortex in said primary combustion chamber for substantial combustion. - View Dependent Claims (18, 19)
