ABSTRACT:
A reactor chamber of a fluidized bed reactor has an internal circulation of particles. Larger recirculated particles are prevented from contacting heat transfer surfaces by classifying particles adjacent the bottoms of the reactor chamber using a particle chamber having a barrier wall with holes or slots of a maximum dimension of less than about 30 mm. The heat transfer surfaces may be disposed in the particle chamber. Larger particles flow down the walls of the particle chamber into the reactor chamber, and some fine particles within the particle chamber are preferably recirculated back to the fluidized bed. The barrier wall is preferably the top wall of the particle chamber, and may be refractory lined with furrows, and/or may be formed of water tubes connected together by fins, with the holes or slots formed in the fins.
