CDMS were consulted to investigate the design of a carbon reaction kiln that was exhibiting severe cracking over a brief operating period. Carbon reactivation kilns are used for catalyst recycling in mining processes.
The work required analysis of the current design to establish if the arrangement was causing the fatigue damage or if it was primarily a result of process conditions.
The analysis conducted by CDMS specifically included detailed static and combined stress analysis of the retort assembly. Linear and non-linear thermal heat transfer calculations and associated thermal stress analysis for fatigue damage assessment were included.
Analysis results were reviewed to draw conclusions as to existing design flaws and recommendations made to remedy the design with minimal wastage and down time. The new design recommendations were validated through numerical analysis by CDMS to relevant industry codes and standards.
