The simplest type of scrubber ash collector is a centrifugal scrubber, in which a water film runs down the wall, so the ash, separated due to inertial forces, is better removed from the scrubber into the hopper, and ash re-entrainment from the walls by the gas flow is reduced. Scrubbers have the ash collection efficiency of 0,82 ... 0,90.
