| Abstract |
The paper discusses nitrogen oxide (NO)/char reactions at pulverized-coal flame conditions. The effective rate of the NO/char reaction, measured over the temperature range 1250 to 1750 K, was found to be retarded by water vapor and enhanced by carbon monoxide (CO) by amounts that decrease with increasing temperature. This is consistent with a hypotehsis that the NO/carbon (C) reaction is retarded by the formation of a chemisorbed layer that can be removed by reaction with CO. Support for the hypothesis is provided by transient experiments which show that, at low temperatures, NO reacts with C to form nitrogen (N2) and a chemisorbed oxygen (O2) layer, and that the chemisorbed O2 decomposes at higher temperatures to form CO or reacts with CO to form carbon dioxide (CO2). |
