Anhydro Fluid Bed Design SPX FLOW offers a wide range of different Anhydro fluid bed designs enabling us to offer the optimal solution to any By providing a significant part of the required energy through application. Many important factors influence the design and heating panels, the need for fluidising air as energy carrier is shape of fluid beds. reduced. This has the following advantages: • Low air throughput (low energy consumption) • High thermal efficiency Plug flow is obtained in three different ways: • Smaller bed area, i.e. smaller and cheaper plant • With a long and very narrow...

F I N E S S E PA R AT I O N The upper part of the fluid bed is often designed according to the actual need of dedusting or fines separation. By widening the flow area of the upper part a lower air separation velocity is achieved and thereby a smaller fraction of the fine particles is removed with the air, i.e. a larger part of the fines falls back into the fluidised bed. inlet section

The most common air treatments are: The most common closed cycle systems are: • Heating (directly or indirectly), • Self-inertising systems • Superheated water vapour systems In cases where the...

The term “self-inertising” system is used for a drying system, in In inert gas systems the drying takes place in an inert gas which the oxygen content is reduced, and which comprises: atmosphere – usually nitrogen. • Direct heating by gas or oil combustion Inert gas systems are used: • Condenser for the circulating gas, condensing the • When an organic solvent is to be evaporated in the fluid bed water vapour • When the actual product is sensitive to oxygen Atmospheric air is supplied as combustion air to the gas or • When other reasons call for a special, specific drying atmosphere oil...
