| Popis: | Pavement material production requires a highly intensive energy processing related to the drying and the heating of granular materials within a rotary kiln. Thus, a better prediction of thermophysical parameters of bituminous concrete materials during their transformation is required to improve the processes in order to reduce their environmental impact. The present paper deals with accurate thermodynamics balance in a mix-asphalt plant. We report input and output mass flows captured within an instrumented flight rotary kiln devoted to a large range of asphalt materials. Hot-mix (Tmaterials ∼170°C), warm-mix (Tmaterials ∼120°C) and Recycled Asphalt Products (so-called RAP) are compared. Computation of the macroscopic energy balance exhibits an averaged energy flux source equal to about 7 MW, the major amount being connected to the power gas burner. The heat sink related to the drying is different according to the formulation, RAP particles having non-negligible moisture content. In situ temperature sensor... |
