This paper presents a comprehensive set of in situ gas species concentration measurements of O2, CO2, CO, NOx, SOx, HCN, and NH3 and particle composition measurements of ash, carbon, hydrogen, and nitrogen taken in a 0.3 MWe pulverized coal flame in a controlled profile reactor with well-defined and controlled wall temperature and inlet flow characteristics. An evaluation of the effects of varying coal mass mean particle size, equivalence ratio, and secondary air swirl number on the measured data is shown through a graphical analysis of the data. Mass and carbon balances were calculated to ensure closure and overall accuracy of the data set. A series of seven combustion tests were conducted using Utah Blind Canyon high volatile bituminous coal. A water quenched probe was used to collect gas and solid samples from an average of 27 distinct locations in the reactor. Coal mass mean particle size, equivalence ratio, and secondary air swirl number were varied one at a time throughout the tests. Two tests were repeated twice to demonstrate the accuracy of reactor test conditions through repeatability of the data. A graphical analysis of the data shows that the repeatability of test conditions was very good except for the sensitivity of a centrally located recirculation zone to reactor settings. Carbon and mass balances were obtained for all test using the data presented in this paper and other temperature and particle data collected concurrently by other researchers.
