Description |
Outline: 1) Introduction 2) Objectives 3) Experimental setup 4) Methodology to quantify flame stability 5) Results and discussion 6) Conclusions 7) Acknowledgements. The objective of this presentation is to better understand, the effects of partial pressure of O2 in a) the coal transport jet, and b) the secondary oxidant jet, and also the effects of other burner operation parameters on co-axial coal jet ignition and flame stability. To contribute to validated, turbulent diffusion coal flame simulations that predict the effects on flame stability of conversion from air fired to oxy-fired conditions in existing units. To develop techniques to quantify coal flame length and stand-off distance from photo-images to allow quantitative comparison with simulations, together with uncertainty quantification. |
