In one aspect, exemplary embodiments of the present invention may be useful in, for example, residential or commercial environments. Aspects of the present invention may supply an oxy-hydrogen fuel as an alternative heating source to petroleum based systems. Aspects of the present invention may generate oxy-hydrogen fuel on demand rather than storing a static supply of fuel.

Moreover, another aspect of the present invention provides a control system for enabling generation of oxy-hydrogen fuel under safety conditions.
- Referring now to
FIG. 1 , a schematic of an oxy-hydrogen generation control system 100 (also referred to as the “system 100”) is shown in accordance with exemplary embodiments of the present invention. Thesystem 100 may include acontroller 110, aburner assembly 120, and an oxy-hydrogen generator 160. Thesystem 100 may also include amanifold 130 between theburner assembly 120 and the oxy-hydrogen generator 160. Aflashback arrestor 150 may be positioned between themanifold 130 and the oxy-hydrogen generator 160. Anon-combustible air source 140 may be coupled to themanifold 130. - In one aspect, the
controller 110 may be configured to control the production of oxy-hydrogen and the feed of oxy-hydrogen to theburner assembly 120 safely. For example, thecontroller 110 may be a programmable device, for example, a microprocessor including non-volatile memory incorporating instructions to operate elements of thesystem 100. It will be understood that lines emanating from thecontroller 100 to other elements in thesystem 100 may be electrical connections carrying signals. - In one exemplary embodiment, the
controller 110 may be coupled to athermostat 115. Thethermostat 115 may be programmable to indicate to the controller 110 a threshold temperature that is needed at a heat distribution source (not shown), for example, a furnace or a hot water system. Aswitch 170, for example, a relay, may be coupled between thecontroller 110 and the oxy-hydrogen generator 160. When the thermostat is below the threshold temperature, thecontroller 110 may be configured to close theswitch 170 so that a power supply (not shown) is delivered to the oxy-hydrogen generator 160. In one exemplary embodiment, the oxy-hydrogen generator 160 may be an electrolysis system carrying a water reserve that is converted into oxy-hydrogen fuel on demand rather than stored. - Referring now to
FIGS. 1 and 2 , thesystem 100 and an enlarged view of theburner assembly 120 is shown in accordance with an exemplary embodiment of the present invention. Theburner assembly 120 may include a micro-nozzle 125 and a primaryfuel ignition nozzle 126. The micro-nozzle 125 may be proximate the primaryfuel ignition nozzle 126 so that fuel being expelled by the micro-nozzle 125 may be ignited by a lit primaryfuel ignition nozzle 126. The micro-nozzle is utilized in this low pressure application to insure a positive exit pressure is maintained prohibiting any potential burn back and to insure the gas travels to the center of the primary flame pattern insuring even heat distribution. Thecontroller 110 may be connected to theburner assembly 120 so that theignition nozzle 126 may be enabled and ignited by igniters 123 by commands from thecontroller 110. An ignitionthermal sensor 127 may be proximate theignition nozzle 126. Thecontroller 110 may be connected to the ignitionthermal sensor 127 to determine based on feedback from thethermal sensor 127 that verifies theignition nozzle 126 is indeed lit. - Referring now to FIGS. 1 and 3A-3C, the
system 100 and various configurations of themanifold 130 are shown in accordance with exemplary embodiments of the present invention. Thecontroller 110 may also be connected to themanifold 130. Themanifold 130 may include an electrically activated pneumatic threeposition valve 135 allowing fluid to flow from themanifold 130 throughconduit 175 to the micro-nozzle 125. Theconduit 175 may include an internal volume insufficient to support combustibility within the line, for example, less than 200 mL. Thecontroller 110 may control the position of thevalve 135 between an oxy-hydrogen gas delivery mode, an air purge delivery mode, and a closed mode.FIG. 3A shows the oxy-hydrogen gas delivery mode where thevalve 135 oxy-hydrogen gas to flow throughsection 131 to theburner assembly 120.FIG. 3B shows the air purge delivery mode where thevalve 135 closes thesection 131. Thus, the flow of oxy-hydrogen gas through to theburner assembly 125 is cutoff. Meanwhile,section 137 is opened, allowing non-combustible air from anair source 140 to flow into theconduit 175 and purging any residual oxy-hydrogen gas from the line to theburner assembly 120. The air source may be under low pressure, for example, less than 100 psi.FIG. 3C shows the closed mode wheresections conduit 175. - Referring now to
FIGS. 1 and 4 , use of thesystem 100 through a series of steps of amethod 400 are illustrated according to another exemplary embodiment of the present invention. Instep 405, thesystem controller 110 may be activated. Instep 410, thecontroller 110 may determine is power is available. If not, instep 415, thecontroller 110 may wait for power to be available or thesystem 100 may enter a shutdown mode. If power is available, instep 420 thesystem 100 enters a ready state. Instep 425, thecontroller 110 may receive temperature level request from thethermostat 115 activating thecontroller 110 to supply heat to a heat distribution source. Instep 430, thecontroller 110 activates theprimary burner unit 120 control which initiates primary fuel ignition at the primaryfuel ignition nozzle 126 and may check if theignition nozzle 126 is indeed lit. If thecontroller 110 determines that theignition nozzle 126 is not lit, then thecontroller 110 may activate an alarm until thenozzle 126 is lit or thesystem 100 is shutdown. If thenozzle 126 is indeed lit, then instep 440, thecontroller 110 may provide power to the oxy-hydrogen generator 160 to produce oxy-hydrogen gas and move thevalve 135 into oxy-hydrogen gas delivery mode where the oxy-hydrogen fuel may be combusted in theburner assembly 120 and the resultant heat is delivered to the heat distribution source (not shown). Instep 445, thecontroller 110 may receive an indication from thethermostat 115 that the temperature threshold is reached and additional heating is not needed. Instep 450, thecontroller 110 may open theswitch 170 and cut off power to the oxy-hydrogen generator 160. Thecontroller 110 may also move thevalve 135 into the air purge delivery mode for a predetermined time, for example 10 seconds and thevalve 135 may then enter into the closed mode. Instep 455, thecontroller 110 may wait until thethermostat 115 indicates the need for more heating or the system may then proceed into a shutdown instep 460. - It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
