ABSTRACT:
The invention concerns the method of feeding particles at multiple points into a fluidized bed by forming at least one auxiliary fluidized bed of the particles and fluidization fluid from which the particles in fluidized state are introduced through a system of inlets into the main fluidized bed. The invention relates to equipment for performing the method consisting of at least one chamber for formation of the auxiliary fluidized bed including the inlet of solid particles and a grid for the inlet of fluidization fluid, and a chamber for the main fluidized bed including the inlet of fluidization fluid, and a system of inlet pipes by which both chambers are mutually interconnected. The system of inlet pipes has the cross-sectional area smaller than 10% of the horizontal cross-sectional area of the main fluidized bed.
