Refractory Modeling
First-principles engineering analysis and advanced modeling were used to develop a low-cost solution for a blast air distribution inlet main experiencing frequent refractory failures. Piping flexibility analysis was used to identify issues causing refractory damage and locate new expansion joints. Finite element analysis was used to develop a custom-designed elbow-to-elbow tie-rod system to ensure thermal loads are not placed on connecting piping. Computational fluid dynamics analysis determined heat transfer coefficients through elbows. Cast refractory design changed to a more reliable brick refractory design. This approach allowed for design optimization and verification, ensuring an improved blast air distribution system campaign life.
