Method of regulating mass streams
 A method of adjusting the mass stream and flow density of a finely divided, fine-grained solid fuel is described. The method uses a dosing container having a fluidized bed at its bottom part and into which the solid fuel is charged above the fluidized bed. A fluidizing gas is adjustably fed to the bottom part of the container and a compensation gas is fed to the upper part of the latter. Mass stream parameters and density are measured in the discharge or supply pipe communicating with the fluidizing bed and the required weight of flow of the fluidizing gas is computed by a computer. In this manner, the regulation of the mass stream is effected by adjusting the loose density of the charge of the dusty material in the container.
