BOC is helping Saint Gobain Glass to boost productivity at one of its European furnaces.

The company has installed its 35th CGM(tm) advanced melting technology system on one of Saint Gobain's float glass furnaces, which produces glass used around the world in automotive manufacturing and building construction.

In a 90-day trial in late 2005, the CGM technology enabled Saint Gobain to boost production by 19 per cent over air fuel operation, and nine per cent over the conventional oxy-fuel boosting technologies used in the furnace before the CGM system was installed.

Following the trial, Saint Gobain agreed to adopt the technology under a longer-term contract.

'Our plant has never achieved the higher pull rates obtained by the use of the CGM technology without damaging the superstructure of the furnace. The CGM technology exceeded our expectations for increasing pull while maintaining our exacting product quality,' said Claude Voide, international technical director, Saint-Gobain Glass.

The BOC CGM technology melts glass faster than side-fired configurations by directly applying oxy-fuel flames on the batch in the furnace. The resulting improved heat transfer rate has several benefits, including better quality, increased pull, decreased furnace size, decreased NOx emissions and improved thermal efficiency.

The European country location or financial terms of the contract were not enclosed.
