ABSTRACT:
A circumferentially stirred variable residence time vortex combustor including a primary combustion chamber for containing an annular combustion vortex and a first plurality of louvres peripherally disposed about the primary combuston chamber and longitudinally distributed along its primary axis, the louvres inclined to impel air circumferentially about the primary axis within the primary combustion chamber, to cool its interior surfaces, to impel air inwardly to assist in driving the annular combustion vortex in a helical path, and to feed combustion in the primary combustion chamber. The vortex combustor further includes a second annular combustion chamber and a narrow annular waist region interconnecting the output of the primary combustion chamber with the second annular combustion chamber for passing only lower density particles and trapping higher density particles for substantial combustion in the annular combustion vortex of the primary annular combustion chamber.
