Abstract
Pressurized water is introduced into a steam production apparatus and system to produce steam. Electrical power is supplied to the apparatus though spaced apart electrical terminals which, in combination with two insulating elements, form a chamber to heat water introduce into the apparatus and chamber to turn the water into steam. The steam can be used for various purposes including powering of steam turbines for generating electricity, driving machinery, and for providing heat for heating systems. The generated steam can be used for various other purposes.
Description
- The invention relates to steam generation and to a device and system for generating high pressure steam.
- Water heaters have existed in many forms, such as boilers where water is heated by applying heat to the water container. In more advanced systems, such as the diathermal water heater in U.S. Pat. No. 5,506,391. In this system electrical oscillations are generated by an electrical controller, the oscillations being applied to a heater through which water flows while providing oscillations to heat the water.
- Another heater system is described in U.S. Pat. No. 7,764,869. This system also provides electrical oscillations to the electrodes in a diathermal heating chamber. This system also requires the liquid to be heated to have a predetermined minimum concentration of dissolved solids which are replaced when the minimum concentration falls below a predetermined concentration.
- The invention relates to a steam production apparatus and system to produce wet and dry steam for various purposes, including powering of steam turbines for generating electricity, driving machinery, and for providing heat for heating systems. The generated steam can be used for various other purposes.
- The technical advance represented by the invention as well as the objects thereof will become apparent from the following description of a preferred embodiment of the invention when considered in conjunction with the accompanying drawings, and the novel features set forth in the appended claims.

FIG. 4 shows a plurality of steam generating units connected together to produce steam and supply it to one steam outlet. -
FIG. 1 illustrates thesteam generating device 10 of the present invention.Device 10 has an outertubular structure 16 with an input opening 17 into which pressurized water in introduced intosteam generating device 10.Input opening 17 may have a oneway valve 9 to prevent the steam generated from flowing out the water input opening. There is asecond opening 18 from which steam leaves thesteam generating device 10. There is a changeable oradjustable nozzle 21 on second opening 18 which is a nozzle with an output opening 22 which is smaller than thechannel 18 a (FIG. 2 ) to limit the output of steam from the steam generating chamber. This causes an increase of the pressure of the output steam. There is a firstelectrical contact 19 and a secondelectrical contact 20 to which the electrical power is applied. There are twonon-conductive ends outer structure 16 encloses and electrically isolates the internalelectrical elements FIG. 2 . -
FIG. 2 is a cross-sectional view of the entire structure. There are twoelectrical terminals electrical elements Elements insulating structure 13, which electrically isolateselements FIG. 3 ) into which the water is introduced viainlet 17 to produce steam which exits throughoutlet 18 andnozzle 21 which has anoutput 22 which is smaller that thechannel 18 a(FIG. 2 ) to increase the output pressure. Anouter enclosure 16 is positioned around internal chamber 31 (FIG. 3 ) formed by electricalconductive elements insulating structure 13, which has twoparts FIG. 3 ).Enclosure 16 is spaced apart from theinternal chamber 31 by spacing 32 and held in position byend mounts 14 and 15 (FIG. 1 ) which hold the electrical elements apart, insulating them from each other. Each of theparts inlet 17 andoutlet 18 are heat resistant non conductive material. Theelectrical elements insulating structure parts FIG. 3 ), A current will flow from, for example,electrical element 11 through the water toelectrical element 12. This current flow turns the water into steam. The amount of steam that flows out of the steam chamber 31 (FIG. 3 ) is limited by the reduced output opening 22 innozzle 21 thus increasing the pressure in the chamber and of the output steam. - As shown in
FIGS. 1 and 2 , electrical power is applied toelectrical terminals contact 11 to contact 12 heats the water and converts the water to steam. Several different voltages can be applied toterminals elements nozzle 21 within about 15 seconds after power was connected toterminals -
FIG. 3 is a cross sectional view 3-3 ofFIG. 2 . Shown is theouter structure 16 enclosing the tubular steam generating structure made ofelectrical elements insulators insulators chamber 31, in which the steam is formed. Theend mounts 14 and 15 (illustrated inFIG. 2 ) hold theouter structure 16, and tubular structure comprised ofelements opening 17 into which water is introduced and opening 18 from which steam exits. As the current flows betweenelectrical elements - The present invention does not require an electronic controller as required in the prior art. Steam is simply generated by passing electrical current through water between
electrical elements -
FIG. 4 illustrates amulti-unit system 40 for generating steam. There are foursteam generating units FIGS. 1 and 2 . They are connected to consecutively generate steam in series. Each of thesteam output openings steam line 45. Steam then exits out opening 46, which may be a nozzle. Theelectrical terminals terminal input lines Control units steam generating units - Operation of multi-unit system is as follows. Electrical power is connected to each of the units, 41, 42, 43 and 44. Water flows only into
unit 41 throughinput 61. Steam will only be produced inunit 41. For example, with a power input of 240 volts A.C., the current flow can be initially about 40-60 amps. As steam is produced, the current could fall to as low as about 15 amps. This is possible as steam is not as conductive as water. By introducing water into the steam units 41-44 one at a time, the amount of current required is limited. When all units are producing steam the current required at any one time should be limited to about 40-60 amps. With each unit drawing approximately only about 15-20 amps, the total required could be limited to about 60-80 amps total. If units 41-44 were all supplied with water at the same time, the current could rise to about 200 amps. By sequentially introducing water in the four units, the current could be limited, thereby limiting the power required to produce steam. Since current in each unit should drop to about 15-20 amps in about 15 seconds, the multi-unit systems should be producing steam in all units in 60 seconds or less.Units timers Timer 55 would openvalve 56 after approximately 15 to 20 seconds allowing water to flow throughinput 62 intosteam unit 42,timer 57 would openwater valve 58 after approximately 30-40 seconds allowing water to flow throughinput 63 intosteam unit 43, andtimer 59 would openwater valve 60 approximately 45 to 60 seconds after allowing water to flow throughvalve 60 and throughinput 64 to steamunit 44. These times are after water is initially supplied towater input 70.
