Abstract: In this study, the exergy performance of a biomass drying system was analysed using MATLAB-based simulations under varying operating conditions. Maximum exergy efficiency was 42.3%, while maximum exergy destruction occurred at elevated inlet air temperatures. These results emphasise the reliance of system performance on operating parameters, and the relevance of critical points for improvement regarding energy efficiency. The results presented herein are anticipated to stimulate the development of more effective and sustained biomass drying technologies.
