ABSTRACT:
In a fluidized bed reactor particles are internally circulated, moving down the walls forming the reactor chamber. A particle chamber having a particle gathering top wall with a horizontal projection area A is disposed in the downward flow of particles. Openings (e.g. holes or slots) with a controlling dimension of about 30 mm or less are provided in the top wall, the openings having total open area B less than half the area A. Heat transfer surfaces may be disposed in the particle chamber.
