| Research Abstract |
We developed fundamental theory to achieve ultra-clean and high efficiency coal combustion for zero CO_2 emission(O_2/CO_2 coal combustion) simultaneously. The conditions are shown to use high CO_2 concentration, which is the feature in O_2/CO_2 coal combustion, for low-NO_x combustion. The lowest NO_x conversion ratio in O_2/CO_2 combustion is lower than it in air combustion by 40%. Moreover, it is shown that carbonate, which has a potential to affect ash deposition and gasification, is formed due to the mineral reaction with CO_2.
