A cyclone separator arrangement includes a preceding apparatus having an outlet, and a cyclone separator having an inlet. The arrangement further includes a crossover duct connected to the outlet and the inlet for supplying gas flow including particles from the preceding apparatus to the cyclone separator. The preceding apparatus has a horizontal inner diameter (D), and a flow channel having a cross-section having a height (H) and a width (d), said width (d) relating to the inner diameter (D) such that 0.15×D<d<0.6×D.

Cyclone separator arrangement

A fluidizing nozzle for introducing fluid into a fluidized bed reactor and a fluidized bed reactor. The fluidizing nozzle includes a nozzle tube limiting at least a part of a feed channel in which fluid is configured to flow, at least one fluid discharge opening arranged near a downstream end of the nozzle tube, and a pot-like hood, which sealingly closes the nozzle tube with a hood cover of the pot-like hood at the downstream end of the nozzle tube at which said at least one fluid discharge opening is provided. The feed channel is provided with a flow restriction element defining at least one flow restriction feed channel upstream of said at least one fluid discharge opening.

Fluidizing nozzle and fluidized bed reactor

A device for cooling a fine-grained solid includes a fluidized bed cooler/heater in which the solid is fluidized with a fluidizing gas and thereby releases energy in the form of heat within the cooler/heater at least two cyclones which are connected in parallel. The cyclones are arranged such that after the fluidization of the solid the fluidizing gas passes through the cyclones so contained particles are removed.

The invention relates to a process and its relating plant for thermal conversion of aluminum chloride hydrate into aluminum oxide and gaseous hydrogen chloride. In a first step, aluminum chloride hydrate is fed into a decomposition reactor where it is heated to a temperature between 120 and 400&#xb0; C. Afterwards, the partially decomposed aluminum chloride hydrate is finally calcined to aluminum oxide at a temperature between 850 and 1200&#xb0; C. in a second reactor. The aluminum chloride hydrate is admixed with aluminum oxide in an intensive mixer with a mass ratio between 1:1 and 10:1 aluminum chloride hydrate to aluminum oxide for using a fluidized bed reactor as a decomposition reactor.

A cyclone for the separation of solid particles and/or at least one liquid from a fluid, featuring a housing, an inlet opening for introducing the fluid together with the solid particles and/or the at least one liquid into the housing, a discharge port for the solid particles and/or the at least one liquid, a dip tube for discharging the fluid from the housing, and at least two guide vanes. Each guiding vanes shows a geometrical form with at least three edges e, e, e. Further, each guide vane is directly or indirectly fixed to the housing with at least one edge eat a fixing point, whereby an area a is defined as the cross-sectional area of the housing intersecting the fixed edges e. In addition, each guide vane shows at least two edges eand ewhich are not fixed to the housing, whereby the first edge ehas a distance dand the second edge ehas a distance d, and whereby d&#x3c;dto the centerline c of the housing. According to the invention, the first edge eshows a distance Lto the area a and the second edge eshows a distance L, whereby L&#x3e;1,25*L
