Boundary Conditions for Designing the Lining of a Glass-Founding Furnace with Innovative Parameters to Improve Technical Efficiency

Resumo

This article presents results obtained from numerical modeling of external heat exchange in an innovative gas-fired glass-founding furnace with an output of 2.92 tons/m²·day). Unit heat consumption in the furnace is 4.187 MJ/kg. Boundary conditions are determined for designing and building a lining for the working space of the furnace. It is established that the average and maximum temperatures are 1512.6 and 1608.4°C for the roof, 1548.3 and 1596.3°C for the longitudinal wall (on the burner side of the furnace), and 1553.2 and 1622.2°C for the end wall (next to the flow). The average temperatures of the surface of the bath in the founding and fining zones are 1404.8 and 1426.6°C, respectively.
