ABSTRACT:
A water-cooled skimmer is provided for a glass-melting furnace. The skimmer includes a platinum plate which is designed to fit closely within the interior of the throat of a glass-melting furnace and extend transversely thereof. The plate is rectangular and is peripherally cooled, with a coolant passage extending along the lower edge and side edge portions of the plate and having end portions extending outside the throat for connection with a coolant inlet and outlet. A supporting member is affixed to the plate and extends horizontally therefrom, being supported by the side walls of the throat, and an additional coolant passage preferably extends along the support and is in heat-exchange relationship with the upper edge of said plate. The cooling of the skimmer provides a long life therefor and also causes the molten glass tending to flow between the side edges of the skimmer plate and the side walls of the throat to solidify or freeze, thereby preventing the molten glass and impurities from flowing therearound. The skimmer takes up little room longitudinally of the throat and can be inserted as a repair skimmer in an existing throat through a narrow slot formed therein, greatly facilitating the repair.
