BOC Gases has licensed its patented CGM advanced heat transfer technology to Stein Heurtey SA of France.

Stein Heurtey, one of the largest suppliers of glass melting and manufacturing equipment, will incorporate the BOC CGM technology into the furnaces it designs and builds for glass makers around the world.

Dick Marshall, glass marketing director of BOC Gases, said: "Incorporating the CGM technology from BOC in a new furnace allows manufacturers to reduce the size of furnace needed for the same capacity output, thus reducing capital costs and energy per ton of melted glass."

CGM technology is being marketed worldwide by BOC and under license by Linde AG, Linde Gas Division, Germany. To date, BOC and Linde have installed over 35 CGM melting systems at existing furnaces in many segments.

The CGM system from BOC melts glass faster than side-fired configurations by directly applying oxy-fuel flames on the batch in a glass-melting furnace. The resulting improved heat transfer rate brings a number of benefits, including; better quality, increased pull, reduced furnace size, reduced nitrogen oxide emissions and improved thermal efficiency.
