In these years, glass industry has several problems to solve which are derived from environmental protection, energy saving, resource saving, demands for high quality glass and so on. Refractory for the glass melting also has some problems corresponding to the glass industry, such as more corrosive service circumstance, less glass contamination from the refractory, recycling and so on. NOx reduction, one of the environmental protection, brings the oxy-fuel combustion and/or the reducing atmosphere operation of glass melting into the glass industry. Under the reducing atmosphere, some kind of refractories can not endure for a long period of time and under the oxy-fuel combustion, refractories ought to endure around 3 to 4 times more severely corrosive circumstance. Thus, the problems of refractory that are corresponding to the glass industry are explained and discussed in this presentation. The solutions for the above are also discussed and presented, if possible in the presentation. |
