Method for renewing a glass making operation coolant

摘要

A method for renewing a recirculating coolant employed to cool various devices used in the production of glass before the level of hardness and solids content of the coolant increases beyond acceptable limits. The coolant, comprised of tap water and a rust or corrosion inhibiting material, is circulated within a closed system. A measured quantity of the coolant is withdrawn at frequent intervals from the closed system and used as the liquid medium in making up batches of raw glass making materials. Like quantities of demineralized or soft water, and additional rust inhibiting material, are added to the coolant remaining in the system for maintaining the hardness and corrosiveness of the coolant in a range that inhibits the build up of deposits and rust and corrosion within the closed system, respectively.
