Abstract
A system for separating solid particles from the combustion products of coal in which high temperature, high pressure flue gas containing the particles is directed tangentially into a cyclone separator so that the relatively large particles are driven by centrifugal forces to the inner wall of the separator. Electrical charges generated at ambient temperature are blown into the cyclone separator via aerosol charge-carriers which charge the relatively small particles in a manner so that the small charged particles are attracted to the wall, which is of an opposite polarity, and are scrubbed off the wall by the larger particles. A double-cone flow regulator is positioned in the path of the aerosol charge carriers and the particles to direct the carriers and particles toward the inner wall. An outlet is provided at the lower portion of the cyclone separator for discharging the separated particles and an additional outlet is provided for discharging the clean gas.
