    摘要: Disclosed is a fluidized bed system which includes a fluidized bed reactor, a solids separator and a return line and serves to carry out exothermic processes in a circulating fluidized bed for large thermal capacities. Secondary gas is introduced into the reactor on a level which is at least 1 meter above the bottom of the reactor. The fluidized bed system is provided with one or more displacing bodies, which cover 40 to 75% of the bottom surface area of the fluidized bed reactor and have a maximum height that is equal to one-half of the height of the reactor to ensure a satisfactory transverse mixing of the oxygen-containing secondary gas and fuel in reactors having large dimensions.
