Method and apparatus for controlling the viscosity of glass streams

摘要

The disclosure embraces a method of and apparatus for transferring heat from streams of glass flowing from a feeder through the use of a closed hollow heat exchanger unit or instrumentality containing a working fluid for rapidly absorbing heat from intensely hot glass streams to raise the viscosity of the glass of the streams to enable attenuation of the streams to fibers and thereby attain increased throughput of glass and higher production of fibers.
