<p>An apparatus for the transportation and conditioning of particulate material, comprises a chamber (11) having an inlet (11a) for receiving material to be transported, an outlet (11b) for the transported material, gas inlet zones (13) in the chamber wall for the passage of gas (air and/or steam) under pressure into the chamber and gas outlet zones (14) in the chamber wall; conditioning means (17) including gas heating/cooling means (18), and gas humidifier means (19); duct means (16) for connecting said conditioning means (17) to said chamber (11) to feed the latter with conditioning gas under pressure; and means (20) for driving or drawing the conditioning gas through the chamber via the inlet (13) and outlet (14) zones. The inlet zone (13) and said outlet zone (14) have gas guide surfaces disposed transversely of the direction of transport along said chamber which guide surfaces are so positioned in the chamber wall and so dimensioned as to cause the gas to have a transverse velocity component directed to urge the transported material away from the wall of the chamber whilst being pneumatically conveyed along the chamber.</p> |
