<p>PURPOSE:To remove soot contained in an exhaust gas simply and efficiently by introducing said exhaust gas containing soot into an atmosphere in which at least oxygen and/or water exists and carrying out electric discharge in this atmosphere. CONSTITUTION:When removing soot contained in an exhaust gas, the exhaust gas containing the soot is introduced into an atmosphere in which at least oxygen and/or water exists and electric discharge is carried out in this atmosphere, thereby, removing the soot contained in the exhaust gas. As for the means of electric discharge, the quantity of discharge is controlled based on the detected result of the quantity of the soot, and a pulse corona discharge is employed. For example, a combustion device 1 is formed by stretching a nichrome wire 3 on the axial line of a cylinder part 2, and a high frequency current is allowed to flow in the nichrome wire 3, to generate silent discharge over the whole tube length. Thereby, the soot in the exhaust gas can be removed simply and efficiently.</p> |
