Finite Element based thermal analysis of a rotary Kiln seal

Lamella type seals are widely used in rotary kilns for sealing the connection between a rotating kiln and the stationary parts. In the present research work, a finite element based methodology is developed to predict the temperature distribution across a rotary kiln seal installed in a cement plant. Loads and boundary conditions are arrived based on literature and the plant data. Experimental measurement of temperature on the parts of kiln seal has been carried out using a non-contact type infra-red thermometer. A steady-state thermal analysis has been performed to predict the temperature on the kiln seal. It is found the Finite Element results are in good agreement with experimental results.
