Fused cast refractories are widely used in glass soda-limee-silica furnace superstructures due to their high resistance to corrosion by the furnace atmosphere. However exudation of the vitreous phase ofAZS refractories at high temperatures, can lead to the formation of defects in the glass, especially during furnace start-up. The ability of the furnace to digest these inclusions may not be sufficient to avoid production losses for glass makers. To solve this problem, a new fused cast AZS refractory named ER2001SLX has been developed. It offers a zero exudation level under typical glass furnace operating conditions and maintains or enhances all other positive characteristics offused-cast AZS.

In response to tightening environmental and legislative pressures, Pilkington has developed a unique technology for the reduction of NO x emissions from most glass melting furnaces, including float glass. The technology, called 3R (Reaction and Reduction in Regenerators), has been successfully demonstrated on several types of glass furnace, ranging in output from 500 to 5000 tonnes/week. The results of extensive trials show that this technology is able to achieve the highest environmental standards, but at considerably lower overall costs than any competing process. This paper outlines both the theoretical and practical aspects of this patented technology and compares it with the main alternatives-selective catalytic reduction and oxy-fuel firing.

The lifetimes of different glass tanks can vary greatly between a few months and several years. Lifetime depends on many factors including the glass composition, furnace temperature and daily glass pull rate. The duration of a tank campaign is determined by the extent of wear within the tank and the subsequent failure of important functions. The following glass contact areas of the glass tank are critical: dog house; throat; bubbler area and barrier wall. Cladding with molybdenum sheet can protect these critical areas of the glass tank against wear, maintaining their performance and reliability for longer periods. Of course, this helps to sustain melting efficiency, glass quality and, may, significantly improve the service life of the glass tank. An important issue is the possible impact of molybdenum reinforcements on the operating parameters of an electrically (Joule) heated glass tank. To demonstrate that there is no relevant influence of the reinforcements mathematical simulations were undertaken.
