Primary glass melting furnaces were made of mud and clay bricks and the most used fuel was wood. These furnaces changed and improved over time and their body was made of refractory bricks instead of mud and clay, and today, with the innovation of various refractory products, their lifetime has increased from a few months to 10-15 years. Glass melting furnaces are thermal chambers in which the glass melts using fuel combustion or electricity. In this paper, glass melting furnaces and their related issues are discussed with a practical and experimental approach so that it is useful for the glass industry.First, main areas of a glass melting furnace are reviewed and adverse factors which may reduce the furnace lifetime are identified and introduced and different related assumptions are discussed and investigated. Also the suitable refractory selection methods for different areas of the melting furnace are discussed. Finally, a few points related to maintenance and repair of various areas of the furnace are stated.
