Abstract
The invention relates to a process for introducing fluids into a solids flow of a spouted bed apparatus, as well as an associated apparatus. For the present invention, it is characteristic that at least one circular solids flow is formed in the axial direction of the reaction space of the spouted bed apparatus, for which the inlet air required for forming the solids flow is fed through a gap in the lower region and in the axial direction of the reaction space and the fluid is introduced by means of one or more single or multiple-component nozzles at one or more positions into the solids flow. Therefore, the flow conditions in the injection region can be set, so that the fluid can be introduced selectively and adjustably into the solids flow. The resulting end product distinguishes itself through approximately equal grain size with equal material properties. Through the spraying of pure fluids, solutions, molten masses, or the like through one or more single or multiple-component nozzles into the solids flow, different end products can be produced.
