Abstract:
1. Method for regulating the quantity of circulating solid in a circulating fluidized bed reactor system having a fluidized bed reactor, the method comprising: tangentially feeding a solid flow/gas flow mixture leaving the fluidized bed reactor into at least one cyclone separator; separating the solid flow from the gas flow within the cyclone separator; recirculating at least a portion of solid flow to the fluidized bed reactor through a recirculation line; exhausting the gas flow through a gas outflow opening in the cyclone separator; and directing a partial quantity of the solid flow quantity from a wall of the cyclone separator to the gas outflow opening with a jet blast from at least one gaseous free jet emitted from a nozzle, whereby a particle spectrum of the solid flow quantity circulating in the circulating fluidized bed reactor system is substantially maintained after separation into two partial quantities of solid flow.
