Abstract
Near-exit measurements of NO, HCN, NH;1 and coal burnout an: reported for a highmoisture,subbituminous pulverized coal fired with air in a laboratory combustor. Test variableswere coal moisture level, stoichiometric ratio and swirl number for the secondary inlet air stream.Data arc also reported for the undried coal wherein gas-char samples were obtained from throughoutthe combustor. Concentrations of major gas species, clcmcn tal composition of the char, gasmixture fraction and N-pollutant concentrations are reported. Effects of coal moisture on burnoutwere negligible and only small decreases in NO levels wereobserved when coal was dried. Resultscan be used for evaluation of predictive models.Keywords
