Combustion Science and Technology Experi

This article examines the combustion regimes occurring in a small-scale laboratory cylindrical combustor, in which the burner and the exhaust port are mounted at the top end of the combustion chamber. The study aims to investigate the dynamics of combustion processes in this specific setup, considering various operational parameters. A combination of experimental methods was employed, including the measurement of flue-gas composition data and hydroxyl radical concentration to analyze combustion performance. The results indicate distinct patterns of combustion depending on the fuel-air mixing ratios and burner configurations. It was observed that conditions leading to stable combustion regimes significantly affect the emissions profile, notably the production of pollutants such as NOx. Additionally, the experiments provide insights into optimizing the design and operation of small-scale combustors for enhanced efficiency and reduced environmental impact. These findings contribute to a better understanding of combustion behavior in controlled environments and offer practical implications for industrial applications aiming for cleaner combustion technologies.
