Under the FutureGen 2.0 project (https://www.futuregenalliance.org/) sponsored by the U.S. Department of Energy, a novel process is used to convert coal into electricity with minimal greenhouse gas (CO2) emissions to the atmosphere. In the process, coal is combusted in a boiler with pureO2; the heat released produces steam, which is then used for heating and to drive turbines that generate electricity. An excess ofO2is supplied to the boiler to convert all the coal into a flue gas consisting of carbon dioxide, steam, and any unreacted oxygen. The mass flow rate of coal to the boiler is 50 kg/s, andO2is fed in 8.33% excess. For the purposes of this analysis, the chemical formula of coal can be approximated asC5H8O2.
