Abstract
The steam generator is provided with electrodes each of which is constructed with at least one longitudinally slotted tube into which a plate is placed in order to deflect incoming water from a central source tangentially into the tube. The deflecting plate is secured against one side of the slot and projects into the electrode tube to form an opening into the tube interior and has a free end within the tube. A trough collects excess water below the plate for delivery into the tube. The delivered water flows in a helical path within the tube while being heated to steam. The water discharge nozzles in the base of the electrode are partitioned so that water flows continuously and evenly from the electrode to prevent arcing below the electrode.
Claims11
An electrode for a water-jet electrode steam generator comprising
- a water-collecting box including at least one vertically disposed cylindrical tube having a vapor outlet in upper portion, a water outlet at a bottom thereof and a slot in a wall thereof for passage of a flow of water into said tube;
- and
- each said tube having a deflecting plate extending through said slot and disposed to deflect a flow of water impinging thereon into said tube and tangentially of said wall, said plate being mounted in sealed relation to one side of said slot and disposed to pass between the center of said tube and the opposite side of said slot to form a free opening, said plate having a free end located within said tube downstream of the flow of water.
An electrode for a water jet electrode steam generator comprising
- at least one cylindrical tube defining a water collecting chamber having a vertically disposed longitudinal axis, each said tube having a vapor outlet in an upper portion, a water outlet in a bottom thereof, and a longitudinally disposed slot in a wall thereof between said outlet and bottom for entry of water into said chamber;
- and
- each said tube having a deflecting plate extending through said slot into said tube, and having a free end within said tube, said plate being disposed to deflect a jet of water impinging on said plate into said chamber and onto said wall tangentially of said axis.
In a water-jet electrode steam generator, the combination of
- a circumferential array of electrodes for heating water to steam, each said electrode including at least one cylindrical tube defining a water collecting chamber having a vertically disposed longitudinal axis, said tube having a vapor outlet in an upper end, a water outlet in a bottom thereof and a longitudinally disposed slot in a wall thereof above said bottom for entry of water into said chamber;
- a plurality of deflecting plates, each said plate extending through a respective slot of a respective tube with at least a number of said plates having a free end in a respective tube, each said plate being disposed to deflect a jet of water impinging on said plate into a respective chamber and onto said respective wall tangentially of said axis;
- and
- means within said array of electrodes for directing jets of water onto each respective plate.
