PPG Industries' fibreglass business is collaborating with other leaders in glass manufacturing and affiliated organizations on two projects funded by the U.S. Department of Energy.
The team comprises PPG, the Gas Technology Institute, Corning Inc, Owens Corning, Schott Glass Technologies Inc, Johns Manville, CertainTeed Corp, Fluent, Inc, A.C. Leadbetter and Son Inc, Praxair Inc, Combustion Tec/Eclipse and the New York State Energy Research and Development Authority. Over the next three years they aim to design, fabricate and validate an oxygen-fuel-fired submerged combustion melting system using a $3.8 million grant. Adoption of this technology throughout the glass manufacturing industry would increase energy efficiency, reduce capital costs and simplify glass-manufacturing systems.
Another grant provided $125,000 for PPG, the Combustion Tec brand of Eclipse Inc., and the Diagnostic Instrumentation and Analysis Laboratory (DIAL) at Mississippi State University to assess furnace operations and model a method of saving 1 to 5 percent of the total energy consumed by a single glass furnace. The project used a PPG fibre glass furnace with a Combustion Tec burner that was assessed using data collection methods devised by DIAL for high-temperature environments. Data showed a 10 percent increase in energy transfer to the glass and a 20 percent reduction in generation of nitrogen oxides (NOx). The team has documented and written a protocol for achieving energy efficiencies and is in the process of reporting on energy improvements and the assessment methodology.
