ABSTRACT:
An electrical steam generator includes a plurality of spaced trays disposed in a vertical axis within a pressure vessel defining a steam generating chamber. Alternate trays are electrically connected to the pressure vessel while the other trays are electrically insulated therefrom. Each tray has an overflow over which sump a film of water flows downwardly into the next lower tray to sump in the vessel below the trays and from which water is pumped to the uppermost tray. The other trays and vessel are connected to an electrical power source. Each tray is provided with a flat horizontally disposed stilling element at the overflow to calm the water in the tray, a perforated vertical water and steam permeable stilling wall upstream of the overflow and a vertical water impermeable shielding wall downstream of and spaced from the overflow. The spacing of the shielding wall provides a gap with a horizontal dimension greater than the maximum expected thickness of the film of water flowing out of the respective tray. The stilling element may be designed to float on the water in the tray.
