Refractory Tiles for Improved Recovery Unit Floor Tube Protection, 2004 11th International Symposium on Corrosion in the Pulp and Paper Industry
Floor tube overheating in Chemical Recovery Units (CRUs) is a significant concern due to the danger of smelt water
reactions. The highly corrosive nature of molten smelt and the environmental concerns and restrictions with
chromium based refractories have resulted in disappointing service life for many refractories. This paper will
present the development and field experience of Alstom’s smelt resistant refractory floor tiles - SmeltGuardTM.
