摘要： The present invention is related to methods and apparatus for improving distributions of both spent catalyst and transport gas into a regenerator of a fluid catalytic cracking unit. Spent catalyst and transport gases move upwardly through a spent catalyst riser and are diverted in a radially outward direction by a deflector cone. The catalyst and transport gas are re-mixed as they move radially outward between two disks before discharging from the outer edges (perimeter) of the distributor into the regenerator in a substantially uniform radial direction. The distributor is adapted to provide continuous discharge from its perimeter so as to cover the entire cross-section of the regenerator.

摘要： A process of continuously conveying granular solids from a first zone with a pressure of 4 to 16 bar through a descending line and via an ascending line to a second zone with a pressure which is lower than in the first zone by 3 to 15 bar, by means of a gaseous medium. To ensure that the pressure between two regions can be reduced at low cost and with little maintenance effort when continuously conveying granular solids, a gaseous medium is injected into a tube through an upwardly directed nozzle at the point where the granular solids are conveyed through a descending line into an ascending line.

摘要： An electric motor is operatively connected to a reel for selectively storing, paying out, and rewinding an air lance of a device for unloading catalyst from tubular reactors. The electric motor powered reel provides improved on/off control of the air lance mounted on the reel, a braking force during withdrawal of the air lance from the reel, constant speed operation during rotation of the reel, and avoids the problem of lubricant contamination of the catalyst and reactor tubes.

摘要： The invention provides an improved method and apparatus for feeding solids to a fluidized bed reactor. A back pressure control valve regulates the pressure drop between the pressure above a solids column in a standpipe and the pressure in the reactor. Solids are fed from the standpipe via a conduit without valve means, the conduit contains a bend of an angle greater than the angle of repose of the solids.

摘要： A system for the control and conveyance of particulate material from a standpipe to the furnace of a circulating fluidized bed boiler. Aeration means positioned in a first area of a conduit transports particulate material deposited by a standpipe to a second area of the conduit. Upon such relocation, additional material from the standpipe enters the first area of the conduit as a replacement for the previously removed material. Fluidizing means in the second area of the conduit fluidizes this removed material causing it to achieve a generally uniform level within this second area. As the height of this level exceeds that of the lower edge of a discharge opening, the fluidized material passes through this opening and into the furnace of a circulating fluidized bed boiler.

摘要： Mobilization apparatus for the treatment, drying for example, of particulate material comprises a mobilization zone bounded by upwardly divergent walls. Particulate material in the zone is mobilized by being subjected to a flow of gaseous mobilizing medium supplied at a multiplicity of sites of the divergent walls. The material is simultaneously subjected to a flow of gaseous accelerating medium supplied in an upward direction from a lower region of the mobilization zone. The obtains in the mobilization zone of circulatory pattern comprising downward flow at the divergent walls and upward flow from a lower region of the zone.In order to discharge the particulate material from the apparatus, a mask extending outwardly from the lower end of an upwardly extending discharge duct is brought to the upper end of the mobilization zone. The result is that the circulatory pattern is destroyed and the material is pneumatically transported up the discharge duct.

摘要： The invention relates to an arrangement for transporting disintegrated solid particles, in which the particles are transported by a quantity of air placed under an over pressure. The weight ratio of the particle/aix mixture lies within a range at which particle transportation gives rise to migrating particle agglomerations. Transportation of the particles is terminated in a particle agglomeration equalizing arrangement, from where the particles are transported further in the form of a particle/air mixture which has been equalized in time. Particle transportation is effected by at least two stages. A first stage in which the weight ratio of the particle/air mixture is greater than 15, and a second stage in which the weight ratio of the particle/air concentration is greater than 5 and lower than the weight ratio of the particle/air mixture in the first stage. The arrangement is used for transporting powdered coal to a powdered-coal burner connected to a combustion furnace.
