| Abstract: | The experiments of deeply oxygenating roasting of lead oxide (litharge) particles at high temperature were conducted in a moving bed with 0. 25m I. D. and 2. 4m in height. The effects of roasting temperature and particle residence time on the product quality and the bed temperature profiles were investigated. The optimum operation conditions for high quality and low cost were determined. A two-dimensional mathematical model for heat transfer between gas and solid in the moving bed was developed. The experimental results show that product purity reaches up to 99.7% and meets the national standard. The calculated results are in good agreement with experimental data. The model has been used in the design of industrial equipment. The equipment has been put into operation successfully. |
