  • Method and apparatus for controlling a stream of solids
    Patent number: 8602693
    Abstract: A method for controlling at least one of a level of solids and an inventory of solids in a solids tank includes withdrawing a stream of solids from the solids tank via a downer. The stream of solids withdrawn from the solids tank is fluidized at a bottom of the downer by supplying a conveying gas so as to convey the withdrawn stream of solids upward via a riser branching off from the downer, a size of the conveyed stream of solids being adjusted by the supplying of the conveying gas. At least one of the level and the inventory of the solids in the solids tank is used as an adjustment variable of a control circuit and a volume flow of the conveying gas is used as an actuating variable of the control circuit.

  • Method and apparatus for dividing a stream of solids
    Patent number: 8225936
    Abstract: A method for dividing a stream of solids includes discharging the stream of solids via a first downer. The stream of solids are fluidized at a bottom of the first downer by supplying a first conveying gas. By the first conveying gas, a part of the stream of solids are conveyed to a top of a first riser branching off from the first downer. A remaining part of the stream of solids are discharged via a second downer adjoining the first downer. The remaining stream of solids are fluidized at a bottom of the second downer by supplying a second conveying gas. By the second conveying gas, a part of the remaining part of the stream of solids are conveyed to a top of a second riser branching off from the second downer.
