Title: Method and apparatus for controlling thermal environment in a glass fiber forming process
Inventor: JENSEN THOMAS H
IPC: F28F27/00
Filed: 1988-12-16
Granted: 1993-09-21
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for controlling a glass fiber forming environment is disclosed.  A fin cooler having a plurality of hollow cooling fins, each provided with a coolant liquid flow passage and further having a header block provided with separate coolant liquid inflow and outflow channels, is placed in a closed loop coolant liquid circulation network.  Water may be employed as the coolant, but preferably a heat transfer liquid having a boiling point higher than water, low vapor pressure, and a high specific heat values is used as the coolant liquid.  The heat transfer liquid takes on heat from the glass fibers as it passes through the cooling fins, and gives up this heat in a heat exchanger which may use plant process water or forced air as the secondary heat transfer medium.  By regulating fluid flow, fin temperature can be manipulated to improve process control and product uniformity.  The cooling fins operate at a temperature high enough to prevent glass volatiles form condensing on the fin surfaces and to prevent the formation of fin corroding acids.  The closed loop cooling path prevents fin coolant passage occlusion or clogging.
