(195e) Oxy-Coal Combustion For CO2 Control

Oxy-fuel combustion is gaining more support as a viable CO2 capture alternative for reducing CO2 emissions from the power plants. This paper will discuss ongoing work in three key areas of oxy-coal combustion. First, recent work evaluating the impact of oxygen purity and CO2 purification requirements on the cost of purification will be shown. A comparison between retrofit and grassroots scenario will be presented and importance of higher efficiency will be highlighted. Second, ongoing work on non-cryogenic oxygen sources will be discussed. Finally, experimental work on the effect of oxy-coal combustion on key operating parameters, such as slagging and carbon burnout will be described.
