Abstract
Disclosed is provided to overcome problems of conventional methods using each of a solid discharge nozzle and a screw conveyer. According to one exemplary embodiment of the present invention, a fluidized bed system is provided to circulate solids using pressure and density difference. More particularly, a fluidized solid circulation system using pressure and density difference is characterized by comprising: a first fluidized bed reactor; a second fluidized bed reactor; a first cyclone; a second cyclone; a first pressure control valve; a second pressure control valve; a lower loop seal; an upper loop seal; and a control part, thereby circulating the solids between the first fluidized bed reactor and the second fluidized bed reactor.
