  • Patent number: 8388711
    Abstract: The present disclosure provides an apparatus and method for removing particulates from a gas stream. The apparatus includes a ceramic filter, at least one electrode, and at least one conductor. The electrode is located at an end of the filter and produces an atmospheric glow discharge in order to oxidize carbon deposits trapped in the filter. The conductor extends at least partially into the filter and acts as a counter electrode. Through various arrangements of the electrodes and conductors, the present disclosure provides closer connection between the trapped carbon deposits and the electrodes. This improves the regeneration of the filter without increasing the size and/or weight of the apparatus.
    Type: Grant

  • Patent number: 4013866
    Abstract: A heating device which produces a plasma flame of elongated cross-section comprises a plasma torch and means for generating a magnetic field. The nozzle of the torch has an elongated exit aperture, across which the magnetic field is directed, and the torch incorporates at least one internal electrode arranged so that when an arc is struck between it and the nozzle the arc root at the nozzle will move along the aperture under the influence of the magnetic field.
