Abstract

Coal gasification with CO_2/O_2 mixtures rather than with air (N_2/O_2 ) recently attracts much attention to reduce CO_2 release into the atmosphere and to increase the efficiency of the gasification. To implement the Integrated coal Gasification Combined Cycle (IGCC) system efficiently and to mitigate the CO_2 emission problem, it is necessary to study CO_2/O_2-blown coal gasification. In this study, numerical simulations of coal gasification including soot formation are conducted with the aim of describing the coal gasification behavior under CO_2/O_2/N_2 atmosphere. The detailed reaction mechanism of coal volatiles under CO_2/O_2/N_2 atmosphere is developed. The numerical model considering transport phenomena with soot formation in the gasifier is developed. The results obtained from this study are considered to be an important step towards better designs of gasifiers.
