System for protecting glass structures in a combustion zone

摘要

A system for protecting glass structures in a combustion zone wherein heat refractory material is applied to the glass structure. The applied heat refractory material substantially is opaque and non-reflective to visible light and also is resistant to degradation at temperatures of up to about 2500 degrees farenheit. The heat refractory material acting to absorb radiant energy and to inhibit the devitrification of glass structures maintained at temperatures elevated to about 1000 degrees centigrade for extended periods of time.
