Abstract

1. A device for the thermal treatment of solid particulate substances in a circulating fluidized bed with recovery of product gases, comprising an elongate fluidization chamber (1) of vertical axis into whose lower portion the solid particles are introduced and fluidized by an an upwardly directed oxidizing gas flow ; at least one recirculation cyclone (2) for the solid materials which communicates via its upper portion with the upper portion of the fluidization chamber (1) ; a duct (3) for recirculating the solid materials via which the lower portion of the recirculation cyclone (2) communicates with the lower portion of the fluidization chamber (1) ; and means for the recovery and treatment of the product gases taken from the upper portion of the recirculation cyclone (2), characterized in that the recirculation cyclone (2) comprises means (17) for injecting reagent gases into the turbulent flow of gase and solid particles which is formed in its upper portion, to form a reaction zone for the circulating solid materials and gases inside the recirculation cyclone (2).
