Abstract

A high-voltage hot water boiler includes a plurality of fluid heating units arranged parallel to each other. Each fluid heating unit includes a cylindrical housing which serves as a counter-electrode. Each housing is provided with a fluid inlet and a fluid outlet so that fluid to be heated can be conducted therethrough and the housing is supported so that the fluid flow path is closer to the horizontal than to the vertical. An electrode extending in the flow direction is provided in each housing for cooperation with the counter-electrode to electrolytically heat the fluid flowing through the flow path. A nozzle, which may be electrically conductive, is associated with the electrode to direct incoming fluid towards the latter. An electrically-insulating sleeve surrounds the electrode and is movable by an adjusting means both in and opposite to the flow of the fluid to modify the flow of current between the electrode and counter-electrode. The adjusting means also simultaneously adjusts the position of the nozzle means relative to the electrode. Manifolds connect the fluid inlets and the fluid outlets of the units together for parallel fluid flow. The adjusting means of the units are ganged together for simultaneous operation.

Dependent claims

An apparatus for heating fluids, particularly a high-voltage hot water boiler, comprising at least one fluid-heating unit, each of said fluid heating units including a housing formed of electrically conductive material and serving as a counter electrode, said housing having an inlet for conducting fluid to be heated in a path through said housing and an outlet for conducting heated fluid from said housing;

means for supporting said housing so that the flow direction of said fluid path is closer to the horizontal than to the vertical;
an electrode electrically insulated from said housing and extending in said flow direction and cooperating with said counter electrode so as to electrolytically heat the fluid flowing in said path;
modifying means for modifying the electric current flow between said electrode and said counter electrode as a function of position, said modifying means comprising a carrier movable within said housing, a sleeve of electrically insulating material mounted on said carrier so as to move with the latter both in and opposite to the direction of fluid flow to or through a position in which said sleeve at least partly surrounds said electrode, and adjusting means connected to said carrier for moving the same to or through said position in which said sleeve surrounds said electrode;
and flow control means including a nozzle located at one end of said carrier adjacent to said inlet for directing incoming fluid substantially towards said electrode.

flow control means provided in said fluid path for directing the flow of fluid substantially towards said electrode, said flow control means being formed of electrically conductive material and being electrically connected with said housing;
and means for varying the spacing between said flow control means and said electrode so as to vary the flow of electrical current between said electrode and said counter electrode and thereby handle different loading requirements.
