ABSTRACT:
Carbonaceous particles are removed from an exhaust gas stream by passing the stream through a frustoconically shaped bleaching zone into which a similarly shaped diverging beam of laser radiation that is absorbed selectively by the particles is directed countercurrent to the stream. The radiation is reflected within the zone to increase the radiation density in the zone over that generated by the laser directly.
