Abstract

A container (1, 11) comprises a bottom (4) which is traversed by air nozzles (3). Air blown through the air nozzles (3) maintains a fluidized bed composed of inert material. Fuel is provided to the fluidized bed after it has reached the ignition temperature. Air entering through the air nozzles (3) to form the fluidized bed is imparted with a movement of which a component (14) provides at least a rotation (7) in a horizontal plane, and fuel is injected to the lower part of the fluidized bed, preferably at about 20% of the height of the bed. Additional air for generating the rotation of the fluidized bed is supplied by an eccentric supply (5). Preferably, at least the air nozzles (3) located close to the wall of the container are sloped with respect to the vertical and in the same direction thereof.
