By a News Reporter-Staff News Editor at Electronics Newsweekly -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventor Krichtafovitch, Igor A. (Kirkland, WA), filed on March 3, 2014, was published online on May 30, 2017.
The assignee for this patent, patent number 9664386, is CLEARSIGN COMBUSTION CORPORATION (Seattle, WA).
Reporters obtained the following quote from the background information supplied by the inventors: "Electric-field-based combustion control systems have been developed to use electric fields to manipulate the movement of electrically charged molecules (e.g., ions) of a charged flame. The flame is created by a combustion process and then electrically charged to generate the charged flame. The electric fields create electrostatic forces within the charged flame. The charged flame can be manipulated to control flame position, flame shape, heat transfer, and other flame characteristics. At the same time, the electric fields can help influence combustion chemistry to suppress formation of pollutants at flame sources.
"Generally, these combustion control systems involve the use of one or more electrodes, such as tubular, planar, or post-type, fabricated from macroscopic metallic sheets, pipes, or rods. Dynamic control of a flame trajectory may be difficult and/or non-effective.
"Therefore, developers and users of combustion control systems continue to develop technologies to improve combustion control systems and methods of manufacturing of combustion control systems."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventor's summary information for this patent: "The present disclosure provides combustion systems, flame control systems, and methods for dynamically controlling flame position and/or shape. In an embodiment, a combustion system is disclosed. The combustion system includes a burner, a flame charging device, and a flame control system. The burner is configured to output a flow including fuel that when ignited generates a flame. The flame charging device is positioned adjacent to the flame and configured to charge the flame to generate a charged flame. The flame control system includes one or more electrodes disposed adjacent to the charged flame, a charge managing module operatively coupled to the one or more electrodes, one or more sensors in electrical communication to the controller, and a controller in electrical communication with the charge managing module and the one or more sensors. The charge managing module is configured to control charging and discharging of the one or more electrodes. The one or more sensors are positioned and configured to measure at least one combustion parameter of the charged flame. The controller is configured to control operation of the charge managing module responsive to the at least one combustion parameter being measured by the one or more sensors.
"In an embodiment, a method for adjusting the position and/or shape of a flame in a combustion system is disclosed. The method includes charging a flame to generate a charged flame, disposing one or more electrodes adjacent to the charged flame, determining a position and/or a shape of the charged flame, and responsive to the determined position and/or shape, delivering bursts of electrical energy to the one or more electrodes to dynamically adjust the position and/or the shape of the charged flame toward a predetermined position and/or shape.
"In an embodiment, a flame control system is disclosed. The flame control system includes one or more electrodes configured to be disposed adjacent to a charged flame, and a charge managing module including an electrical energy device coupled to a pulse transformer that is operatively coupled to the one or more electrodes. The charge managing module is configured to control charging and discharging of the one or more electrodes. The flame control system includes one or more sensors in electrical communication with the controller. The one or more sensors are positioned and configured to measure at least one combustion parameter of the charged flame. The flame control system additionally includes a controller in electrical communication with the charge managing module and the one or more sensors. The controller is programmed to control the pulse transformer to deliver energy to the one or more electrodes responsive to the one or more sensors measuring the at least one combustion parameter of the charged flame.
"Features from any of the disclosed embodiments may be used in combination with one another, without limitation. In addition, other features and advantages of the present disclosure will become apparent to those of ordinary skill in the art through consideration of the following detailed description and the accompanying drawings."
