Abstract: A method of producing an optical fiber is provided that includes the steps of flowing a first gas into an optical fiber draw furnace. The first gas is passed through a heated section configured to contain and heat a glass source from which the optical fiber is drawn, passing the first gas through a muffle which defines a capture chamber. A portion of the first gas is removed through at least one reclaim port operatively coupled to the capture chamber. A second gas flows into a gas screen at a rate configured to substantially recover a pressure drop associated with removing the portion of the first gas.

Abstract: Disclosed herein are methods for regenerating metal catalysts used in the purification of inert gases for use in fiber draw furnaces and other applications. The methods described herein can regenerate metal catalysts alone or in combination with molecular sieves. The methods disclosed herein are able to prevent the formation and retention of unwanted byproducts during and after the regeneration process, thereby efficiently converting oxidized catalysts to their reduced or elemental form. Gases purified with catalysts regenerated by the methods disclosed herein, when used in fiber draw furnaces and similar applications, can lead to extended equipment lifetimes and higher-quality products due to the lack of degradation by contaminants in the gas stream.
