Abstract
A vertical conduit closed at one end by a head wall and connected at its opposite end to a fluidization gas delivery means is provided with side blowing nozzles longitudinally spaced in planes. A shutter is movable inside the conduit so that the bed in which the conduit is disposed in use can be progressively brought into a state of fluidization by supplying fluidization gas to the nozzles successively and cumulatively starting from the top. The invention obviates the need for the introduction via the bottom of the fluidized bed of compressed air at a high pressure when starting up the fluidization of the bed.
