Filed:

Apr 29, 2020

Appl. No.:

16/861658

Inventors:

- Torrance CA, US
Jason M. Sanders - Los Angeles CA, US
Mark Thomas - Torrance CA, US
Patrick Ford - Torrance CA, US
Daniel Singleton - Hermosa Beach CA, US

International Classification:

H05H 1/48

Abstract:

A system for generating and delivering a low temperature, wide, partially ionized tunable plasma stream is described. The system employs a fast rising, repetitive high voltage pulse generator, flowing gas, and a plasma head to produce the described atmospheric pressure plasma stream and its associated active species. The plasma head may have an exit slit with a relatively wide dimension to produce a relative wide plasma stream. Electrodes may be located proximate the exit slit, for example one in an interior of the plasma head via with gas flows toward the exit slit, and the other exterior to the plasma head and offset from the exit slit. The plasma may include baffle material to enhance a uniformity of flow through and across the exit slit. Plasma heads with having exit slit with different widths may be provided as a kit.

International Classification:

B01D 53/34
F24C 15/20

Abstract:

A method and system to treat cooking emissions (e.g., smoke) employs a nanosecond high voltage pulse generator and a transient pulsed plasma reactor. The system is used in a scheme that substantially reduces particulate matter produced in commercial charbroiling processes (e.g., cooking of hamburger meat). Both a reduction in the size distribution and total particulate mass is achieved using the method and system described herein.

International Classification:

F24C 15/20
B01J 19/08

Abstract:

A method and system to treat emissions (e.g., smoke, particulate, odor, grease) employs a nanosecond high voltage pulse generator, a transient pulsed plasma reactor, and a DC voltage source that supplies a DC bias voltage, preferably a negative DC bias voltage to a conductor of the transient pulsed plasma reactor. The system is used in a scheme that substantially reduces at least particulate matter in emissions streams, for example emissions streams produced during cooking, for instance in commercial charbroiling processes (e.g., cooking of hamburger meat), or from operation of internal combustion engines. Both a reduction in the size distribution and total particulate mass is achieved using the method and system described herein.

International Classification:

F02P 9/00
F02P 23/04
F02P 3/08

Abstract:

A system and method for providing multiple fast rising pulses to improve performance efficiency. In one approach, multiple fast rising pulse power is employed to improve fuel efficiency and power of an engine. The system and method can involve a transient plasma plug assembly intended to replace a traditional spark plug. Alternatively, an approach involving a pulse generator and a high voltage pulse carrying ignition cable is contemplated.

F02P 15/04

US Classification:

123445, 313139

Abstract:

A device for providing ignition of a fuel-air mixture using a transient plasma discharge is provided. The device includes an anode coupled to receive a voltage; and a cathode disposed in proximity to the anode and coupled to a ground, wherein at least one of the anode and the cathode includes a protrusion that enhances an electric field formed between the anode and the cathode, the protrusion forming a sharp edge defining a plurality of points, each point forming a path of shortest distance between the anode and the cathode.
