摘要

The global energy crisis underscores the need for alternative energy solutions like biomass-fired boilers. Improving energy efficiency is crucial, with waste heat recovery systems playing a key role. Technologies such as condensing heat exchangers, commonly used in natural gas boilers, recover latent and sensible heat from exhaust gases to reduce energy loss. Adapting this technology for biomass-fired systems can significantly boost their efficiency and sustainability. This study is related to a research project on the development of a waste heat recovery system integrating a condensing heat exchanger an enthalpy wheel to enhance biomass boiler performance. The present work is focused on the analysis of the condensing heat exchanger. In the present initial phase of the investigation, the condensing heat exchanger is analyzed under non-condensing conditions, to provide a basis for the future analysis under condensing conditions. A 3D numerical model using ANSYS Fluent was developed and validated with experimental data to reduce reliance on extensive testing. A mesh independence study, multiple turbulence models and plate angle study ensured result robustness. The strong agreement between methods confirmed the reliability of CFD simulations in predicting the heat exchanger's performance.
