摘要： A fluidized bed reactor includes: a reactor body; a dispersion plate mounted within the reactor body to partition the inside of the reactor body in a traverse direction and having a plurality of holes through which a reaction gas passes; a nozzle unit mounted on one surface of the dispersion plate to receive an inert gas from outside the reactor and inject the inert gas so as to crush deposits on the dispersion plate; a sensing unit configured to sense the deposits on the dispersion plate; and a control unit configured to control operation of the nozzle unit according to information sensed in the sensing unit.
