Determination of Heat Conductivity and Thermal Diffusivity of Waste Glass Melter Feed: Extension to High Temperatures

Popis výsledku v původním jazyce

The heat conductivity (lambda) and the thermal diffusivity (a) of reacting glass batch, or melter feed, control the heat flux into and within the cold cap, a layer of reacting material floating on the pool of molten glass in an all-electric continuous waste glass melter. After previously estimating lambda of melter feed at temperatures up to 680°C, we focus in this work on the lambda(T) function at T } 680°C, at which the feed material becomes foamy. We used a customized experimental setup consisting ofa large cylindrical crucible with an assembly of thermocouples, which monitored the evolution of the temperature field while the crucible with feed was heated at a constant rate from room temperature up to 1100°C. Approximating measured temperature profiles by polynomial functions, we used the energy equation to estimate the lambda(T) approximation function, which we subsequently optimized using the finite-volume method combined with least-squares analysis. The heat conductivity increas
