Patent ID: 7309442

Claim:
A method of controlling a biomass waste stream having a pre-determined flow rate, at least one tube having an inlet and an outlet, a plurality of conductors being disposed in said at least one tube, a power source adapted to provide a pre-determined magnitude of electrical current to at least one of said plurality of conductors, and a control box adapted to measure a second magnitude of electrical current between at least one pair of said plurality of conductors and provide a third magnitude of electrical current to at least one of said plurality of conductors, the method comprising the steps of: collecting said waste stream; passing said waste stream at a pre-determined flow rate into said inlet of said at least one tube; measuring said second magnitude of electrical current between at least one pair of said plurality of conductors; comparing said second magnitude of electrical current with said pre-determined magnitude of electrical current; providing said third magnitude of electrical current to at least one of said plurality of conductors to generally equalize said second magnitude of electrical current with said pre-determined magnitude of electrical current; and passing said waste stream from said outlet of said at least one tube.
