Abstract
A fluidized bed reactor is provided with vertically oriented heat exchange coils for controlling the temperature of the fluidized bed. Tuyere elements discharge fluidizing gas at a level substantially above the constriction plate. The bed solids below the level of the tuyere ports constitute a static layer during fluidization and the lower return bends of the heat exchange coils are embedded in this layer and so are shielded from erosion by the fluidized solids of the bed proper.
