MODELLING OF THE SWELLING OF SIC-BASED REFRACTORY LINING USED IN WASTE-TO-ENERGY PLANTS

Abstract : This work provides a computational model to predict the life-span of SiC based refractories used in waste to energy plant (WTE) linings. In this application, oxygen gas present in the atmosphere diffuses through the porosity and reacts with the re- fractory producing silica (SiO2). This new phase clogs gradually the pores and causes swelling of the refractory lining. The pro- posed thermo-chemo-mechanical model which simulates these phenomena is briefly summarized. The results obtained from the model implemented in a F.E code prove the ability of the model to reproduce qualitatively the swelling of post-mortem bricks taken from WTE linings.
