Abstract:

Based on earlier experiments, this paper compares characteristics of coal combustion and pollutant formation under O₂/CO₂ atmosphere with conventional air by numerical simulation.It focuses particularly on the combustion fundaments， such as flame temperature, heat transfer, and NO_x formations.The results showed that coal combustion under O2/CO2 atmosphere excelled combustion under conventional air.And the obtained data are necessary for reasonably organizing flow field, controlling flame temperature and adopting appropriate O₂ concentration, which help to design new oxy-fuel combustor.
