When the gas flow is too low, respectively the gas velocity decreases and the separation efficiency of the cyclone deteriorates. To have a constant gas flow through the cyclone, some of the already dedusted gas is recirculated to the inlet of the HURRICLON®. The amount of the recirculated gas depends on the required gas flow in the coal mill.
