Heat and Mass Transfer Model for the Thin Material Layer Consisting of Zinc-Containing Pellets in Rotary Hearth Furnace

Abstract:

In this paper, a mathematical model is established to simulate heat and mass transfer process among the thin material layer consisting of zinc-containing pellets while being reduced in Rotary Heath Furnace (RHF). The material layer model is based on a single pellet model, coupling heat and mass transfer and chemical reactions. The model essentially involved solving the unsteady-state equations with appropriate initial and boundary conditions using the control volume formulation. Temperature distribution, gas phase concentration, metallization rate, and dezincing rate have been obtained and discussed.
