摘要： A fluidized bed furnace includes: a lower reactor which forms a first fluidized bed space having a first diameter, and which includes a discharge port through which reduced iron fines are discharged; an upper reactor which forms a second fluidized bed space having a second diameter greater than the first diameter, and which includes a charging port through which iron ore fines are charged; and a tapered part which forms a connecting space that allows communication between the first fluidized bed space and the second fluidized bed space, and which directly connects the lower reactor and the upper reactor.

摘要： A method and an apparatus (50) for producing direct reduced iron (37) from dry pellets (25) composed of iron oxide and carbonaceous material. A mixture of pellets (25) and free coke particles (38) with weight relation from 3:1 to 5:1 is fed into the top of an electrothermal fluidized bed (32) that is fluidized by nitrogen. By exposing pellets (25) in the electrothermal fluidized bed (32)to temperatures of between approximately 850-1,100°C for an average period of between approximately 15-60 minutes, the volatiles are removed and the pellets (25) metallized. Reduced pellets (37) mixed with free coke (38) are discharged from the bottom of fluidized bed (32) and cooled. The reduced iron pellets (37)are physically separated from any free coke (38) and the free coke (38) is recycled back into the fluidized bed (32).

摘要： According to the method, granular ore or ore concentrate is introduced into a kiln (1) for roasting the ore at temperatures of 400 to 1050 DEG C, whereby the ore in the kiln forms a stationary fluidised bed (3). The ore is projected onto the fluidised bed through an opening (16) in the kiln housing located above said fluidised bed, the ore being accelerated by the blades (14a) of a rotating projection wheel. Said projection wheel (14) lies outside the kiln in the vicinity of the housing opening. Preferably, the speed of the projection wheel is variable and the projection wheel can be displaced and/or pivoted in relation to the kiln.

摘要： A method and a device, Fig 1, for sealing an opening (15, 8, 10) between two zones in a fluidized bed and/or between the bed and its surrounding (22). In the bed particles (2) are intended to be maintained suspended by means of a carrier gas, which is introduced in the bottom (3) of the bed below the level of aid opening (15, 8, 10). Through said opening (15, 8, 10) primarily workpieces (6) intended to be treated in the bed are intended to pass, which opening (15, 8, 10) is, for example, a horizontal gap in a vertical partition wall (11, 9) between the zones (12, 13, 14) or between the bed and its surrounding (22). The method according to the invention is characterized in that a heap (19, 27) or several heaps (19, 27) of particles (2), by utilizing the movements of the particles (2) and carrier gas in the bed, are caused to be built up at said opening (15, 8, 10) to such a height that the opening (15, 8, 10) is covered or substantially covered by the heap/heaps (19, 27) of particles (2). Workpieces (6) during their passage through the opening (15, 8, 10), and therewith through the sealing, demolish the heap/heaps (19, 27), whereafter said heap/heaps (19, 27) are built up again during and/or after the passage of the workpieces (6).

摘要： A method and apparatus for feeding solids into the bed of a fluidized bed furnace (18). The feed solids are separated into a fine fraction and a coarse fraction. The coarse fraction is supplied to fluidized bed (16) in an in-bed pneumatic transport feed system or in an over-the-bed feed system. The fine fraction as well as fluidizing air are supplied to fines admission zone (24) wherein the fine fraction and fluidizing air are thoroughly mixed. The mixture of the fine fraction of feed solids and the fluidizing air is then passed upwardly through air distribution means (38) into fluidized bed (16).
