Electrode-type steam generator

Abstract

An electrode steam generator of the type wherein water is directed in free fall from a water distribution device in a stream onto an electrode to generate steam employs a horizontal dish-shaped water distribution device having a circular rim defining a dam to cause a shroud of water to fall onto an electrode of either S-shaped transverse cross section or onto an annular electrode having a convex curvature. The water distribution device receives water from a load proportional supply means and the water overflows the dam in unthrottled manner for all loads of the steam generator. The rim defining the dam is rounded in a downward direction with the curvature thereof extending in each radial plane up to a point with an approximately vertical tangent. A portion of the water falling on the electrode is diverted to provide a gap to allow the release of steam generated within the water shroud.
