COMBINED ASH CATCHER Russian patent published in 2012 - IPC F23J15/00 B01D49/00 

FIELD: machine building.

SUBSTANCE: proposed device comprises filtration element and moving packing working in fluidised bed mode. Set of elements arranged along gas flow comprises cyclone, apparatus with circulating fluidised layer and return cyclone, filtration ceramic element. Disperse particles with capillary-porous structure and size, at least, one order larger than that of ash particles fed with gases from cyclone into apparatus are fluidised. Gas velocity in said apparatus is defined subject to dancing of said particles, their capillary-porous structure being filled with ash particles so that their averaged bulk density makes, at least, 50% of ash density. Particles capillary-porous structure filled with ash particles are drained from layer bottom while these new particle are added to the layer.

EFFECT: improved design.
