✦ Synopsis
This work describes an experimental and predicted assessment of the influence of coal particle size on the formation of NO in a large-scale laboratory pulverized coal flame. A detailed archive of quantitative and qualitative data, including an inventory of stable fuel nitrogen species, was taken from three flames of a high volatile coal: one of standard size (46/zm) and the others of a small (25 ~zm) and large (121 txm) particle size segregation, respectively. The formation/destruction mechanisms of nitrogen species are found to be subtly changed by the combination of the physical and chemical nature of the combustion characteristics associated with each particle size distribution. For this furnace and burner configuration it was found that both small
