Distributor plate for fluidized bed equipment

---

Abstract

---

The invention refers to a distributor plate (12) for fluidized bed equipment (9) with openings (3) and deflector strips (1) arranged directly above them. It is characterised by the deflection strips (1) having an oblong shape, being mounted longitudinally in the fluidized bed equipment (9), in parallel to the main flow direction (19) of the product above the openings (3) in the base plate (2), and having spacers (6) that form an outflow cross-section around the periphery of the deflection strip (1) for the fluidizing gas, where the base plate openings (3) can be designed advantageously with an oblong cross-section. This ensures good fluidization of the material, while also conveying it.
