TREATING MATERIALS IN A FLUIDIZED BED REACTOR

摘要

A fluidized bed reactor where material from a prereactor is brought into contact with hot particles separated from flue gases. The particles when removed from the flue gases by a separator are passed to a prereactor having a gas supply and vapor removal port where the hot particles are mixed with fresh feed material and the mixture is passed to the fluidized bed reactor for chemical and/or thermal treatment.
