Waste gases leaving glass-melting furnaces attain temperatures as high as 1,200 to 1,400°C (the corresponding temperature range for float-glass furnace is 450 to 550°C). These gases contain a high carry-over of silicates and alkalis, besides residues from heavy oil firing.
Thermax has developed, supplied and successfully installed WHR boilers that recover heat from these exhaust gases to produce saturated/superheated steam for process heating, chilling or power generation applications.
