Abstract

A regulatable bypass device (9) diverts some of the solids particles away from the path (8) for fluidized particles to be treated in the apparatus at a first point (10) and returns them to the path (8) at a second point (11) downstream of the first in the direction of travel of the particles and in the fluidised bed (3) portion of the path (8). By adjustment of the bypass device (9) the apparatus can be adapted to fluctuating temperatures, of the air which is used to maintain the fluidised bed (3), or to fluctuating temperatures of the solids particles to be treated. The bypass device (9) may comprise an adjustable dam (12) (Figure 3), or a twin chute (14) (Figure 7) in which the proportion of particles fed into each chute may be varied.
