This patent describes a dry ash handling system for a combustor, comprising: an ash hopper accepting ash from the combustor and providing a fixed ash height sufficient to allow substantially complete combustion of partially burned objects. The ash hopper includes mixing means for mixing the ash and preventing air channels, and the mixing means comprising an inner wall of the hopper under the combustor angled away from the combustor at a first angle and an outer wall of the hopper angled away from the combustor at a second angle less than the first angle; and ash conveying means, coupled to the bottom of the hopper, for conveying ash away from the hopper at a rate which maintains the fixed ash height.
