| 20130255482 | ELECTRICALLY-DRIVEN PARTICULATE AGGLOMERATION IN A COMBUSTION SYSTEM - Technologies are presented for applying electrical energy to a combustion reaction to produce agglomerated combustion particulates. For example, a system may include: one or more electrodes configured to apply electrical energy to a combustion reaction; a combustion zone configured to support the combustion reaction of a fuel at a fuel source; and an electrical power source operatively coupled to the one or more electrodes and configured to apply electrical energy to the combustion reaction. The combustion reaction is controlled to produce a distribution of agglomerated combustion particulates characterized by an increase in at least one of an average particulate diameter or an average particulate mass. | 10-03-2013 |
| 20130255549 | SOLID FUEL BURNER WITH ELECTRODYNAMIC HOMOGENIZATION - A solid fuel burner may include a system for electrodynamic homogenization. One or more electrodes may apply an electric field to burning solid fuel or a region proximate the burning solid fuel. The electric field causes mixing and homogenization of volatilized fractions of the solid fuel, combustion gases, and air. The improved mixing and homogenization may reduce emission of carbon monoxide (CO), reduce emission of oxides of nitrogen (NOx), reduce oxygen in flue gas, increase temperature of flue gas, and/or allow for a larger grate surface. | 10-03-2013 |

| 20140255856 | FLAME CONTROL IN THE BUOYANCY-DOMINATED FLUID DYNAMICS REGION - A burner system includes a nozzle configured to emit a fuel stream for the support of a flame, and first and second electrodes, each configured to apply electrical energy to a flame supported by the nozzle. The first electrode is positioned in a momentum-dominated fluid dynamics region of the flame, while the second electrode is positioned in a buoyancy-dominated fluid dynamics region. Application of charges to the flame via the electrodes can be employed to control flame characteristics in the buoyancy-dominated fluid dynamics region, such as shape and position. | 09-11-2014 |
| 20140272730 | ACTIVE MAGNETIC CONTROL OF A FLAME - A combustion system can allow for the interaction of a magnetic field and an electrical current within a flame supported by a nozzle. The magnetic field can be generated by one or more electromagnets in proximity to or contact with the flame. The electrical current can be generated by a voltage potential difference generated between a first electrode and a second electrode located at tip and base regions of the flame, respectively. The interaction between the electrical current and the magnetic field can generate a force that can produce a constant lateral movement of ions within flame, generating a vortex that can enhance mixing of air and fuel. The speed and direction of this vortex can be controlled by actively varying the magnitude and direction of electrical currents applied in the one or more electromagnets and the electric current induced within the flame, as well as by varying the spatial relationship between these two factors. | 09-18-2014 |
