<p>PURPOSE:To remove combustible fine particles efficiently, by a method wherein a porous filter is formed from conductive ceramic and a metallic electrode means for heating the filter by passing a current therethrough is provided. CONSTITUTION:To respective filter end surfaces of a short cylindrical porous conductive ceramic filter 1 having a large mesh size and a short cylindrical porous conductive ceramic filter 2 having a fine mesh size, metallic electrodes are formed entirely or partially in a communicated form as metallized layers 4a, 4b, 5a, 5b. To the metallized layer 4a, a circular corrugated metal net 3c made of stainless steel is attached in a contacted state so as to overlap one surface thereof with said layer 4a each other. In addition, a circular corrugated metal net 3b made of stainless steel is provided so as to hold the front and the back surfaces thereof between the metallized layer 4b and the metallized layer 5a in a state contacted with said layers 4b, 5a.</p> |
