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 9MWth heavy-oil-fired...
On-line monitoring of flame stability is crucial as it is closely related to plant safety, combustion efficiency, and pollutant emissions. This paper presents a new method for the stability monitoring of a burner flame using its medial axis. Flame video clips are acquired on a combustion test rig under different combustion conditions. Each frame of the flame video clips is processed and the medial...
This paper presents the design, implementation and evaluation of an instrumentation system for flame stability monitoring and characterisation on industrial furnaces. The system, incorporating digital imaging and spectral analysis techniques, is designed to monitor a range of flame characteristic parameters. The stability of the flame is then assessed through statistical analysis of the flame parameters...
