Unfired drying and sorting apparatus for preparation of solid fuel
The invention comprising a drying and sorting apparatus for preparation of solid fuel prior to firing in a combustion furnace. Unsaturated air/gas is passed through a bed containing a mixture of solid fuel and inert material particles, fluidizing them. The unsaturated air/gas is the drying vehicle. When in a fluidized state, the lighter organically derived solid fuel particles separate from the heavier inert material particles. The air/gas is admitted to the bed directionally in a manner which drives the mixture in a retraceable path to outlet points downstream of the point of feedstock entry, the heavier inert material settling at the bottom and the lighter solid fuel particles rising in the bed. Means are provided in the sorter floor for selectively concentrating and directing the solid inert material to the collection point transversely to the direction of particle flotation.
