Beschreibung
Zusammenfassung:	A fluid bed combustion method and apparatus are disclosed utilizing an induced draft fan downstream of the exhaust port of the combustion chamber. Fluidizing air is given a velocity vector toward one side of the chamber for moving foreign objects to that side where the objects are removed and separated by air classification from bed particles which are returned to the fluid bed. Air classification is accomplished using a blower which is valved off during preheat operation to draw hot air from above the fluid bed down through the particle bed.
