Coal combustion modelling of large power plant, for NOx abatement

This paper presents the comparison of experimental results and computational fluid dynamics (CFD) simulations for a 600 MWe industrial pulverised coal power station. The power station measurements were made in a normal combustion mode and in an overfire air (OFA) mode. The agreement between the model and the data collected in the chimney is good; the NOx reduction modelled is in agreement with the measured one, but data taken in the flame show that the flame structure is imperfectly represented.
