Application of coal combustion model to pulverised fuel furnaces. Backreedy, R.I.; et al. Journal of the Energy Institute, June 2006, Vol 79 No 2, pp 101-109

Standard coal combustion submodels included within computational fluid dynamics codes are simplified in order to reduce computing time and can result in reduced accuracy. The present paper describes a furnace model, which incorporates a detailed coal combustion model allowing predictions of unburned carbon and NOx to be made from basic fuel properties of the parent coal. The model has been validated against experimental data acquired on three large power stations, firing coals with fuel ratios between 1·5 and 2·1. Overall, for accurate predictions of furnace performance the effects of tramp air in leakage must also be taken into account.
