IMPROVED DEVICE FOR PURIFYING COMBUSTION GASES AND FUMES FROM A HEATING DEVICE USING A SOLID FUEL, IN PARTICULAR WOOD

摘要

The invention relates to an improved device for purifying (1) combustion gases and fumes, including an electrode (5) brought to a high voltage for electrifying particles, and a filter structure (7) brought to a different electric potential for attracting the particles in the fumes (H) by the effects of static electricity. A collection means (8), preferably heated to a high temperature by a heating means (13), is combined with a catalytic means, the whole being arranged so as to trap said particles and eliminate said particles by carbonisation or calcination and/or by mechanical vibration. Said invention is useful for manufacturers of wood heating appliances.
