Prior to treatment in a cyclone, the gases are sepd. into two parts. The part contg. dust below the tolerance limit for atm. emissions is released in the air, the part with a higher dust content is processed (instead of by an electrofilter according to 1557112) by methods other than electrofiltration (pref. a hose filter, disc filter, Venturi scrubber or other dust remover). |
