| Abstract | 443 ABSTRACT Rotary kiln incinerators are widely used in the treatment of liquid and solid hazardous wastes. However, the complex transport and chemical processes within the system are still not well understood. The refractory failure caused by liquid slag attack is related to the gas flow and gas temperature distributions. The current paper describes the gas flow and mixing behaviour in an industrial rotary kiln incinerator for disposing hazardous wastes, by using a general purpose CFD-code PHOENICS. The results indicate that the gas flow and mixing inside the kiln is very complicated. The 3dimensional gas flow will help to better understand the heterogeneous temperature distribution inside the kiln, which will affect significantly the bed behaviour and refractory lining wear. In the future, heat transfer within the kiln will be included in this research. The numerical predictions will provide useful information for improved process control. |
