Modeling and simulation of an anode carbon baking furnace

Abstract

The anode temperature profile in a Hydro Aluminium baking furnace is obtained by solving the three dimensional heat equation. The main heat transfer and chemical processes are taken into account. Due to symmetry, one half of a pit is modeled. Along the gas path, submodels are derived for the under-pit area, pit area and under-lid area. For the gas flow, a stationary model is derived, whereas the heat equations are dynamically solved. The numerical model is derived from the control volume formulation.
