Research Topics

The fluidized bed technology possesses various procedural advantages in many industrial processes, as a drying, granulation, agglomeration and/or coating. Often these processes are still associated with high energy consumption, since there is a controlled heating mainly of the air flow (fluidizing gas), i.e. the heating is performed by convection. In that way, however, very little heat energy densities can be obtained and at the same time high energy losses exist.

To increase the efficiency and the economy of the processes taking place in fluidized bed, new technologies for the heating of particles, without accompanying deterioration of the product quality are planned. The emphasis is on the reduction of energy consumption. An alternative method is the inductive energy input into the fluidized bed of inert particles electrically conductive.

In this case, the fluidizing gas is not the source of energy, but the electrically conductive inert particles (such as iron hollow spheres) in the fluidized bed, in which an induction field of energy is transferred. On the surface of these particles, the heat is released directly into the fluidized bed. Here, since the heat is emitted via a large overall surface area of the bed material, a very high energy density and eventually highly efficient heat transfer can be achieved. By energy input into the fluidized bed through inductively heated particles due to the high energy densities and short heating times and the good efficiency, a reduction of energy consumption during particle formulation in fluidized bed processes is sought in the end.

The work on this project will be funded by the Federal Ministry of Education and Research (BMBF) as part of the "InnoProfile transfer" program.
