The vaporized liquid is carried absent by the drying gases. Occasionally to save Power, the exit fuel is partially recycled.
Cures: Clear the filter According to the supplied frequency or all through batch changeover cleaning. Look at the force gradient during the manometer or alarm through the procedure.
Moisture Elimination: The dampness-laden air rises from the fluidized mattress, carrying the evaporated humidity with it. This ongoing circulation of air through the bed makes certain uniform drying.
Involves increased gasoline managing resulting from in depth recirculation of exhaust fuel for high thermal effectiveness Procedure.
