Abstract

An electrode assembly for an electrode boiler employing electric current flow between spaced electrode assemblies immersed in an electrically conductive fluid in a boiler vessel for raising the temperature of the fluid includes an upright electrode member having an internal flow passage terminating in outlet slots in the outer peripheral surface of the bottom portion of the electrode member. The conductive fluid is pumped under pressure through the internal passage and exits through the slots into contact with fluid guide vanes on the electrode member and surrounding the bottom portion thereof. The guide vanes, which may be cupped-shaped or curved, are arranged in the path of the fluid exiting the outlet slots and create fluid circulation adjacent to outer peripheral surface of the electrode member to remove steam bubbles therefrom for the prevention of detrimental arcing.
