Removing particle constituents from fire flue gases has high voltage electrode system in flue to electrostatically charge particles to be collected on anode electrode

摘要

A fireplace flue (2) has a mounting plate (9), in an opening (10) in the building outside wall, carrying a metal grille cathode (5) and cylindrical anode (6) concentrically on the axis (11) of the flue on insulators (7, 8). The anode is further mounted within a tube (13) on supports (16) and the lower end is conically arranged as is the upper end of the outer tube. A high tension voltage is supplied by a transformer and control system (17).
