<p>PCT No. PCT/BR86/00014 Sec. 371 Date Apr. 4, 1988 Sec. 102(e) Date Apr. 4, 1988 PCT Filed Aug. 15, 1986 PCT Pub. No. WO88/01181 PCT Pub. Date Feb. 25, 1988.An apparatus for the oxidation of particles suspended in the air with a refractory material block (4) provided with small volume ducts (5) inside which s resistive wire is passed in order to generate a higher power density. The maximum volume of the ducts (5) is 103m3 and its maximum cross section area is 1 cm2, the ducts being dimensioned in such a way that the minimum permanence time of the air mass in their interior is 1 second and the minimum power density is equal 50 KW/m3. The block (4) may be disposed inside a metal box (7) which also contains a fan, the motor (11) of which is commanded by an electronic control circuit (10) that receives signals related to the block temperature by a thermal sensor (9) disposed within the block.</p> |
