Process regulating the amount of particles circulating in a cyclone reactor system

摘要

Regulating the solid material circulation of a circulating fluidized bed reactor comprises guiding a partial amount (11a) of the solid material stream fed to a return line from the wall (20) of a cyclone separator (4) into a gas removal line (21) using jet impulses of a gaseous free jet (12) formed by a nozzle (13) and feeding the remaining residual amount (11b) to the return line. The grain spectrum of the solid material stream circulating in the reactor system is maintained after dividing into the partial streams. An independent claim is also included for a device for carrying out the above process.
