Abstract

This paper proposes a simple universal index for on-line quantitative assessment of flame stability. The proposed index has a dynamic range of [0, 1] and is designed by combining the dynamic characteristics of seven parameters extracted from flame images in HSI color space. It assesses the flame stability in terms of color, geometry and luminance. Experiments were carried out on a 9MW_th heavy-oil-fired combustion test facility. The impact of the swirl vanes on the stability of a heavy oil flame is investigated. The results obtained demonstrate the effectiveness of the proposed approach to quantitative flame stability assessment.
