Abstract

The steam generator includes a cylindrical tank, a plurality of circumferentially-spaced electrical terminals extending through the tank top wall. To afford the capability of adjusting the horizontal distance between adjacent electrodes while maintaining the sides parallel and uniformly spaced, the underside of the tank top wall is provided with a radially extending row of radially-spaced bosses in conjunction with each terminal and each boss includes an aperture radially aligned with the corresponding terminal. The upper end of each electrode includes a radially-extending row of apertures which are adapted to receive the inner end of a terminal and are spaced so that, when a terminal is positioned in one of the electrode apertures, at least one other is in registration with a tank boss aperture to receive a metal screw or the like for anchoring the electrode on the tank. The electrodes each include a pair of vertical, generally flat, elongated perforated metal side members joined together in angular relationship along an inner edge to form a V-shaped cross-section and have an upper portion with vertical outer edges extending generally parallel to the tank side wall and a thicker lower portion having outer edges which extend at an incline downwardly and radially inwardly from the outer edges of the upper portion and terminate at the bottom in a generally horizontally extending edge.
