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.
