By a News Reporter-Staff News Editor at Journal of Engineering -- CLEARSIGN COMBUSTION CORPORATION (Seattle, WA) has been issued patent number 9496688, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.
The patent's inventors are Krichtafovitch, Igor A. (Kirkland, WA); Wiklof, Christopher A. (Everett, WA).
This patent was filed on November 27, 2013 and was published online on November 15, 2016.
From the background information supplied by the inventors, news correspondents obtained the following quote: "In electrodynamic combustion control systems (ECC), electrical energy is employed to control various aspects of a combustion reaction. Typically, the electrical energy is applied by electrodes in contact with, or in close proximity to the combustion reaction. For example, one known method is to position a first electrode near or in contact with the combustion reaction and employ a burner nozzle as a second electrode. A voltage is then applied across the combustion reaction between the two electrodes, producing an electrical field extending through the combustion reaction, between the electrodes. As fuel (and/or oxidizer) are emitted via the burner nozzle, an electrical charge is imparted to the fuel. This produces a charge to the combustion reaction whose polarity is opposite that of the first electrode. The position of the first electrode, the polarity and value of the applied voltage, and many other related factors determine the effect of the electrical energy on the combustion reaction."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "In an embodiment, a system is provided for employing a flow of charged particles to impart a charge to a combustion reaction. For example, the system may include an ionizer configured to provide an ion flow having a first polarity. The ion flow is introduced to the combustion reaction at a first location with respect to a burner or fuel source of the combustion reaction. The ion flow can be configured to impart a charge to any of a component of the combustion reaction, the combustion reaction itself, or a product of the combustion reaction. According to an embodiment, the system also includes a first electrode positioned at a second location that is downstream from the first location, and a voltage source operatively coupled to the first electrode. The system can also include a controller operatively coupled to provide one or more electrical signals to the ionizer and the voltage source. The controller is configured to control the combustion reaction by selection of the one or more electrical signals to compel a response by the charged combustion reaction.
"In an embodiment, a method is provided for employing an ion flow to control a combustion reaction. The method may include supporting a combustion reaction at a burner or fuel source. The method may also include applying one or more electrical signals to an ionizer to generate an ion flow having a first polarity. The method may further include contacting the charged ion flow to the combustion reaction or a reactant of the combustion reaction at a first location. The first location is at least intermittently upstream with respect to at least a portion of a reaction front of the combustion reaction. The method may additionally include imparting a charge to the reactant of the combustion reaction, the combustion reaction, a product of the combustion reaction, or a combination thereof. The method may include controlling the combustion reaction by applying one or more electrical signals to one or more first electrodes. The first electrode is at a second location that is downstream of the first location. The first electrode controls the combustion reaction by causing the charge to respond to the one or more electrical signals."
