  • A heat-transfer model for the rotary kiln: Part I. pilot

    01.06.1989· A model for rotary kiln heat transfer, which accounts for the interaction of all the transport paths and processes, is presented in a three-part series. In this first paper, the pilot kiln facility is described, and the significant results from the heat-transfer trials are identified. Limestone, Ottawa sand, and pctroleum coke were heated using a range of firing rates, while other operating

    01.06.1989· A model of rotary kiln heat transfer, which accounts for the interaction of all the transport paths and processes, is presented in a three-part series. In this second paper, the development of a unified model for heat transfer at a kiln cross-section is described. Heat transfer within the kiln refractory wall was solved using a finite-difference approximation for one-dimensional

  • A Mathematical Model of Heat Transfer in a Rotary Kiln

    A one‐dimensional axial heat transfer model for an internally heated rotary kiln has been developed. Both predicted temperature profiles and heat transfer fluxes agree well with the experimental data of Barr et al. The simulated results are used to successfully explain for the first time the coupling phenomenon of the bulk bed and covered wall temperatures discussed in previous publications.

  • A thermal model for the rotary kiln including heat

    A mathematical model was developed to predict heat transfer from the freeboard gas to the bed of a rotary kiln. The thermal model incorporates a two-dimensional representation of the bed's transverse plane into a conventional one-dimensional, plug flow model for rotary kilns. The result, a quasi-three-dimensional rotary kiln model, significantly improves the ability to simulate conditions

    A three‐dimensional steady‐state model to predict the flow and heat transfer in a rotary lime kiln is presented. All important phenomena are considered for the pre‐heat and calcination zones including turbulent gas flow, buoyancy, all modes of heat transfer, evolution and combustion of species and granular bed motion with calcination reaction. The model is based on a global solution of three
