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 The stream of solids withdrawn from the solids tank is fluidized at a bottom of the downer by supplying a conveying gas so as to convey the withdrawn stream of solids upward via a riser branching off from the downer, a size of the conveyed stream of solids being adjusted by the supplying of the conveying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.
