Abstract
A fluidized bed reactor includes a furnace defined by side walls, a roof, and a continuous bottom, and has a solid particle bed in the furnace. Vaporizing surfaces form at least two principally vertical chambers. The chambers have a round or polygonal cross section, and extend from the bottom upwards to at least 80% of the height of the furnace. Also, the chambers are spaced away from the side walls of the furnace and are arranged separately within the furnace, for the furnace volume to be free so that the particles move even in the proximity of the chambers.
