Superstructure Corrosion In Glass Tanks: Comparison Of Mathematical Model With Field Measurements

An increasing number of glass tanks are being converted to fuel-oxy firing for environmental or economical reasons. One of the problems associated with conversion is the increased crown wear rates that preclude use of silica as the crown material. Alternative refractory materials are significantly expensive. This paper describes the development of a mathematical model that is used to predict potential areas in the crown where the worst corrosion can be expected. Model predictions are compared with measurements in two glass furnaces.
