  • Compact dual cyclone combustor
    Patent number: 6601526
    Abstract: An apparatus and method of creating a high combustion rate in a combustor used to burn combustible matter. The combustor comprising a cylindrical combustion chamber extending vertically with at least one side loading bin for loading combustible matter into the combustion chamber while combustion is ongoing. The combustor creates a high combustion rate by inducing an acoustic excitation and an ascending vortex in hot gases that is reflected by a conical surface, converting the ascending vortex to a descending vortex. The shear between the ascending and descending vortices increases mixing. The descending vortex acts to separate the small, fully-combusted particles from larger particles that are thrown by centrifugal force back into the combustion zone.
