Abstract
Abstract An improved corona reactor method and apparatus for subjecting a fluid reactant to a corona discharge, and particularly for generating ozone. The corona reactor includes a housing containing an air-cooled, modular, corona reactor core comprising a plurality of separate, individually removable, air-tight corona reactor cells. Each corona reactor cell includes two, spacedapart, metallic electrodes or shell portions defining an airtight corona discharge chamber therebetween. The exterior surfaces of the electrodes are bare and exposed to ambient; the interior (facing) surfaces are covered with a ceramic dielectric; and the fluid reactant is subjected to the corona discharge within the corona discharge chamber by appropriate inlet and outlet ports. The individual cells are electrically connected in series.
