Abstract
Glass-melting furnace is the most essential equipment in float glass manufacturing, which greatly affects the glass quality and energy efficiency. A three-dimensional simulation model of a float glass-melting furnace including combustion chamber and glass tank is performed in this paper by CFD software Ansys Fluent. To evaluate the glass quality with obtained simulation output data, a new fining index is proposed from the view of bubble elimination in fining zone of the glass tank. The fining index is verified effective in this paper by comparisons between simulation results and actual industry data. The simulation model and fining index then provide guidance for operating parameters optimization and glass quality improvement.
