Simulation of coal combustion in high CO2 and O2 environment

This study represented the first in a series to investigate the novel approach of combusting fossil fuels in an environment with re-circulated flue gas as a means to generate a concentrated stream Of CO2 for enhanced oil recovery or coal bed methane recovery. The tool for investigation was a combustion simulation model which was implemented together with experimental studies to develop an optimal approach in re-circulating flue gas. The results of five test cases indicated that the model provided the same trend of variation in combustion, heat transfer and pollutant characteristics as observed in the pilot-scale experiments.
