Recycling Of Refractories From The Glass Manufacturing Industry

Refractories present at the end of campaigns of glass melting furnaces are to a large part corroded, infiltrated by glass and/or have reacted to its components. In addition to the refractories heavily contaminated by melted glass and its vaporized or condensated by-products, other refractories are retrieved, often in large quantities, which are only lightly contaminated or not at all. This paper will discuss the present situationof recycling refractories retrieved from glass melting furnaces by the glass and refractories industries with the aim of initiating the problem solving process.
