METHOD OF HEAT TREATMENT, MAINLY BURNING OF VEGETABLE WASTE IN FLUIDIZED BED Russian patent published in 2006 - IPC F23C10/00 F23G5/30 

FIELD: heat treatment of loose materials.

SUBSTANCE: proposed method of heat treatment of vegetable waste, mainly burning vegetable waste in fluidized bed includes moving waste over gas distributing grate from loading to unloading sections and maintaining sum of hydraulic resistances of fluidized bed ΔP_bed and grate ΔP_gr constant ΔP_bed=ΔP_gr= constant; hydraulic resistance of fluidized bed in loading section ΔP_bed at concentrated delivery is calculated according to: h_gr=h+π(H-h)² ctgα/6 for case B≥L and h_gr=K[h+(H-h))/2] for case B<L where h_gr is rated height of fluidized bed at loading section outlet, m; L is length of loading section, m; L=(H-h)ctgα; h is height of fluidized layer at loading section outlet, m; H is height of loading unit above grate, m; α is angle of repose of material, deg; B is width of loading section, m; K is coefficient.

EFFECT: improved quality of process.
