<p>In a fluidized bed reactor (10) particles are internally circulated, moving down the walls forming the reactor chamber (12, 112, 312). A particle chamber (22, 122, 222, 322) having a particle gathering top wall with a horizontal projection area A is disposed in the downward flow of particles. Openings (32, 132, 232, 332), 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 (40, 140) may be disposed in the particle chamber.</p> |
