Claim 13:
14. An automated volatiles consumption system for a coated scrap metal furnace, said furnace having a delacquering chamber and a melt chamber separated from said delacquering chamber, said furnace having a computer control system, said automated volatiles consumption system comprising:
a. an eductor system having a gas suction port, a gas mixing chamber, a motive gas inlet, and a gas discharge port; said gas mixing chamber being positioned between said delacquering chamber and said melt chamber; said gas suction port opening into said delaquering chamber and said gas mixing chamber; said gas suction port providing a gaseous conduit between said delaquering chamber and said gas mixing chamber; said motive gas inlet opening into said gas mixing chamber and injecting a motive gas into said mixing chamber in an orientation directed away from said gas suction port; said directed motive gas creating a Venturi in said mixing chamber; said Venturi drawing exhaust gases and volatiles from said delacquering chamber and into said mixing chamber; said gases and volatiles from said delacquering chamber mixing with said motive gas in said mixing chamber to form an eductor gas mixture; said gas discharge port opening into said gas mixing chamber and said melt chamber; said gas discharge port providing a gaseous conduit between said gas mixing chamber and said melt chamber; said gas discharge port providing a gaseous conduit between said gas mixing chamber and said melt chamber; said gas discharge port directing said eductor gas mixture out of said gas mixing chamber and into said melt chamber;
b. an igniter, said igniter positioned proximate said gas discharge port in communication with said eductor gas mixture, said gas igniting said eductor gas mixture;
c. an electronic gas flow control loop, said control loop comprising a computer processor, an electronic sensor positioned in said eductor system, and a gas flow regulator positioned in said eductor system; said gas flow regulator controlling the flow of one or more gases in said eductor system; said sensor measuring a first process condition in said eductor system, generating an electronic signal indicative of said first process condition, and communicating said electronic signal to said computer processor; said computer processor controlling said gas flow regulator in response to said electronic signal.
