ABSTRACT:
Upper and lower vortex chambers are disposed immediately below a calcining furnace for calcining powdery raw materials. The scattering clinker particles from a fluidized-bed burning furnace are trapped in the lower vortex chamber and are returned to the fluidized-bed burning furnace so that the scattering clinker particles are positively prevented from flowing into the upper vortex chamber and the calcining furnace.
