Analysis of thermomechanical and failure behavior of refractory linings in a high temperature black liquor gasifier
Keywords and Phrases
Black liquor gasifier
"A coupled thermal-mechanical model accounting for chemical reaction is developed and implemented into a commercial finite element code to simulate the operational behavior of a high temperature black liquor gasifier. Furthermore, a continuum damage mechanics based analytical model is developed to study the failure behavior of the refractory linings of the gasifier. In the study, the heat transfer, thermomechanical behavior, and the failure modes of the gasifier components are investigated. The current work identifies the factors that affect the thermomechanical behavior of gasifier refractories and the steel shell. This work in addition to providing a mechanics and material science based method for the failure analysis of refractories, serves as a guide in the design of components of a BLG gasifier"--Abstract, leaf iv.
