Claim 0:
1. A volatiles consuming eductor system for a coated scrap metal furnace, said furnace having a delacquering chamber and a melt chamber separated from said delacquering chamber, said system comprising:
a. a gas mixing chamber positioned between said delacquering chamber and said melt chamber;
b. a gas suction port, said gas suction port having a first end and a second end, said first end opening into said delaquering chamber, said second end opening into said gas mixing chamber, said gas suction port providing a gaseous conduit between said delaquering chamber and said gas mixing chamber;
c. a motive gas inlet, said motive gas inlet opening into said gas mixing chamber, said motive gas inlet injecting a motive gas into said mixing chamber and directing said motive gas in a direction 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 exhaust gases and volatiles from said delacquering chamber mixing with said motive gas in said mixing chamber to form an eductor gas mixture;
d. a gas discharge port, said gas discharge port having a first end and a second end, said first end opening into said gas mixing chamber, said second end opening into said melt chamber, said gas discharge port providing a gaseous conduit between said gas mixing chamber and said delaquering chamber, said gas discharge port directing said eductor gas mixture out of said gas mixing chamber and into said melt chamber; and
e. an igniter, said igniter positioned proximate said gas discharge port in communication with said eductor gas mixture, said gas igniting said eductor gas mixture.
