FLUIDIZED-BED THERMAL REACTION UNIT Russian patent published in 2000 - IPC

FIELD: burning or gasifying combustible materials containing non-combustible components. SUBSTANCE: unit has slight-dissipation plate, heavy-dissipation plate, and auxiliary dissipation plate each provided with great number of holes to admit fluidized gas and with outlet arranged between auxiliary dissipation plate and heavy-dissipation one to discharge non-combustible components. Some portion of fluidized gas is admitted through outlet for non-combustible components or the latter is made horizontally open. In this way, continuous circulating flow is organized at furnace bottom in fluidized bed. Both slight- dissipation plate and auxiliary dissipation one have their surfaces inclined downward towards non-combustible component outlet. Heavy-dissipation plate is inclined upwards gradually rising as it goes away from point of non- combustible component outlet. In this way, non-combustible components are continuously discharged and do not settled down inside furnace. EFFECT: improved efficiency of burning and gasifying processes. 8 cl, 11 dwg
