Abstract: The method for the distribution of a solid flow (m 0) drawn-off from a cyclone or a fluidized bed container (1), comprises conducting the solid flow (m 0) over a first down pipe (7) and then fluidizing at the bottom of the down pipe by supplying a carrier gas, conveying a part of the solid flow (m 1) towards the top by the carrier gas over a first riser (9) branching off from the first down pipe, leading away the remaining part of the solid flow (m 0) over a second down pipe (13) adjacent itself to the first down pipe and then fluidizing at the bottom of the second down pipe. The method for the distribution of a solid flow (m 0) drawn-off from a cyclone or a fluidized bed container (1), comprises conducting the solid flow (m 0) over a first down pipe (7) and then fluidizing at the bottom of the down pipe by supplying a carrier gas, conveying a part of the solid flow (m 1) towards the top by the carrier gas over a first riser (9) branching off from the first down pipe, leading away the remaining part of the solid flow (m 0) over a second down pipe (13) adjacent itself to the first down pipe and then fluidizing at the bottom of the second down pipe by supplying the carrier gas, and conveying a part of the solid flow (m 2) towards the top by the carrier gas over a second riser (15) branching off from the second down pipe. The supply of the carrier gas is varied at the bottom of the first and/or the second down pipe. The pressure difference over the fluidized bed container is used as controlled variable for the supply of the carrier gas to the first or the second down pipe. The supply of the carrier gas is constantly held at the bottom of the first down pipe. The pressure difference between the bottom and the head of the first and/or the second down pipe is smaller than the pressure loss corresponding to the fluidized down pipe. The pressure at the bottom of each down pipe is larger than the pressure at the head of this down pipe. The conveying air is brought beneath the first and/or the second riser in each case over a downwardly arranged nozzle. The carrier gas is admitted with low volume flow for the interruption of the solid flow in a riser, so that the minimum fluidization speed is not exceeded in the riser. An independent claim is included for a device for the distribution of a solid flow drawn-off from a cyclone or a fluidized bed container.

Abstract: The method involves drawing off of a solid flow by a down pipe (6), and fluidizing the solid flow on a base (8) of the down pipe by a supply of carrier gas. The solid flow is transported to a high level by an ascending pipe (9) branched off by the down pipe, and dimension of the solid flow extracted by the ascending pipe is varied by variable supply of the carrier gas. The level of the flow or solid stock in a solid container is used as a controlled variable, and a volume flow of the carrier gas is used as a correcting variable of a control loop. Independent claims are also included for the following: (1) a method for regulating a temperature and/or mixing ratio in a mixing vessel (2) a device for regulating a level and/or solid stock in a solid container.

Abstract: There are described a method and an apparatus for controlling the level and/or the inventory in a fluidized bed in a fluidized-bed tank, wherein a stream of solids is withdrawn from the fluidized-bed tank via a downer, the stream of solids is fluidized at the bottom of the downer by supplying a conveying gas flow and is conveyed to the top through a riser branching off from the downer. The size of the stream of solids conveyed through the riser is varied by the variable supply of the conveying gas, wherein the level of the solids or the solids inventory in the solids tank is used as a control variable and the volume flow rate of the conveying gas is used as an actuating variable of a control circuit.
