Experimental Study on Nitrogen Oxides Formation of Pulverized Coal during Nonstaged and Staged Oxyfuel Combustion

摘要

1 .Char+CO_2 gasification in oxygen insufficient conditions that enhanced reactivity and CO formation was observed. 2 .Gasification was activated in several cases of O_2/CO_2 and it was along with enhanced mass loss at low SR and high temperature compared to O_2/N_2. 3 .NO_x concentration of oxy-fuel conditions was lower than that of O_2-N_2 conditions and this might be attributed to the high CO concentration (trade-off btw NO_x CO shown).
