Abstract Predictions of two pulverised coal flames issued from a swirl burner are compared with measurements. Both flames are from a high volatile Canadian coal; one is a low NOx flame while the other is a high NOx flame. The paper focuses on flame properties inside and just downstream of the burner quarl. In the computations, the numerical errors have been minimised by application of a second-order numerical scheme and very fine grids. As a turbulence closure, an algebraic stress model appropriate for swirling flows predictions is used. Good quantitative predictions of the flow pattern, temperature, oxygen and carbon dioxide concentrations are achieved. However, the carbon monoxide concentrations are only in qualitative agreement with those measured. Substantial differences in the near-burner-zone properties of the two flames are highlighted in the predictions.
