Definitions

  • 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.
  • more advanced systems such as the diathermal water heater in U.S. Patent 5,506,391 .
  • 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.
  • 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.
  • FIG. 1 illustrates the steam generating device 10 of the present invention.
  • Device 10 has an outer tubular structure 16 with an input opening 17 into which water in introduced into steam generating device 10.
  • Figure 2 is a cross-sectional view of the entire structure.
  • Elements 11 and 12 are secured to an insulating structure 13, which electrically isolates elements 11 and 12 from each other and forms a tubular chamber 31 ( FIGURE 3 ) into which the water is introduced via inlet 17 to produce steam which exits through outlet 18 ( FIGURE 1 ).
  • An outer enclosure 16 is positioned around internal chamber 31 formed by electrical elements 11 and 12 and the insulating structure 13, which has two parts 13a and 13b ( FIGURE 3 ).
  • Enclosure 16 is spaced apart from the internal chamber 31 by spacing 32 and held in position by end mounts 14 and 15 ( FIGURE 1 ) which hold the electrical elements apart, insulating them from each other.
  • Each of the parts 14, 15 and 16 as well as inlet 17 and outlet 18 are heat resistant non conductive material.
  • electrical power is applied to electrical terminals 19 and 20.
  • Several different voltages can be applied to terminalsl9 and 20 and to elements 11 and 12 from approximate 210 volts A.C., to 880 volts A.C., but in testing the steam generated, 240 volts A.C, has been found sufficient to produce instant steam.
  • wet and dry steam was produced and began to flow out of opening 18 within about 15 seconds after power was connected to terminals 19 and 20.
  • FIGURE 3 is a cross sectional view 3-3 of FIGURE 2 .
  • the end mounts 14 and 15 (illustrated in FIGURE 2 ) hold the outer structure 16, and tubular structure comprised of elements 11, 12, 13a and 13b together and provided the opening 17 into which water is introduced and opening 18 from which steam exits. As the current flows between electrical elements 11 and 12, and through the introduced water, the heating of the water by the current flowing through produces steam.
  • 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 11 and 12.
  • FIG 4 illustrates a multi-unit system 40 for generating steam.
  • Each of the steam output openings 45a, 45b, 45c and 45d are connected to steam line 45. Steam then exits out opening 46, which may be a nozzle.
  • the electrical terminals 19a, 19b, 19c, and 19d and 20a, 20b, 20c and 20d are connected in parallel by electrical terminal input lines 50, and 51.
  • Control units 55, 57 and 59 are for determining when water flows into steam generating units 42, 43 and 44.
  • 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 through input 61. Steam will only be produced in unit 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 will 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 limited to about 40-60 amps. With each unit drawing approximately only about 15-20 amps, the total required is limited to about 60-80 amps total.
  • Units 55, 57, and 59 are timers set to open the connected water valves after a set time. Since the current in each steam unit 41-44 should reduce after about 15 to 20 seconds of introducing water into the steam unit, the timers 55, 57, and 59 can be set to open the water valves after the set time.
  • Timer 55 would open valve 56 after approximately 15 to 20 seconds allowing water to flow through input 62 into steam unit 42, timer 57 would open water valve 58 after approximately 30-40 seconds allowing water to flow through input 63 into steam unit 43, and timer 59 would open water valve 60 approximately 45 to 60 seconds after allowing water to flow through valve 60 and through input 64 to steam unit 44. These times are after water is initially supplied to water input 70.
