PULSE REACTOR, FLUIDIZED-BED PULSE UNIT, AND SOLID FUEL BURNING PROCESS Russian patent published in 1998 - IPC

FIELD: endothermic reactions, residue burning, including those in medicine practice and organic wastes, material drying, air heating, calcination, etc. SUBSTANCE: system has reactor vessel 10, device 70 for feeding fluidizable solid material to vessel 10 placed in center of its height, device for feeding fluidizing medium for solid material to vessel placed under solid-material inlet in vessel 10 for producing solid-material fluidized bed between them, heat-transfer device 60 placed in vessel 10 and communicating with fluidized bed to remove heat therefrom, and device 80 for exit of waste gas communicating with vessel 10 and used to evacuate combustion products therefrom; pulse combustion chamber 30 is provided with resonant chamber at outlet facing bottom part of vessel 10 and carrying diffuser 40 on its outlet end to reduce speed of combustion products leaving it; diffuser is arranged so that combustion products leaving it can interact with fuel and fluidized-bed material; vessel outlet device 80 used for evacuating combustion products from it has device 82 for separating solid particles from combustion products and conveying them back to fluidized bed for further reaction; reactor vessel 10 has also device 17 for removing ash and other products from it. EFFECT: enlarged functional capabilities. 35 cl, 9 dwg, 3 tbl
