Method and device for cleaning combustion exhaust gas using plasma

摘要

The present invention relates to a method and device for cleaning of exhaust gas from a power plant burning hydrocarbon fuel including the step of letting the exhaust gas pass a cold plasma excited in a discharge chamber by creeping electric discharge at low, normal or elevated pressure of the exhaust gas. According to the invention volumetric creeping discharge is excited by a system of capacitors connected in series.
