PROCESS OF THERMALLY TREATING FINE-GRAINED SOLIDS IN AN INTERNALLY HEATED FLUIDIZED BED

Granular solids are thermally treated in a fluidized bed utilizing internal combustion. The process is carried out in such a way that the hot load can be varied independently of other operating conditions by supplying at least one third of the air supplied to the fluidized bed as secondary air which...

Beschreibung
Zusammenfassung:	Granular solids are thermally treated in a fluidized bed utilizing internal combustion. The process is carried out in such a way that the hot load can be varied independently of other operating conditions by supplying at least one third of the air supplied to the fluidized bed as secondary air which is fed to the upper half of the height of the fluidized bed below the top level thereof.
