Annular ring burners are widely used in industrial kilns, such as tunnel, shaft, and rotary kilns, because they provide consistent and controlled burning. To investigate how operational parameters, such as air to fuel ratio, air velocity, O2 concentration in combustion gases, and air inlet diameter, affect flame behaviour, including temperature distribution and flame length, this study uses ANSYS Fluent to simulate non - premixed methane flames in a rotary kiln. The results show that lower intake diameters are associated with increased air velocity, which leads to shorter flames. Additionally, compared to flames in combustion gas conditions, flames in ambient air have higher peak temperatures and longer durations.
