Demonstrations of coal-fired oxy-fuel technology for carbon capture and storage and issues with commercial deployment

Biomass devolatilization at high temperature under N2 and CO2: Char morphology and reactivity

“…In this process, the net volume of flue gas (and hence the boiler size) is reduced and a rich stream of CO 2 (> 95%) is produced, which after purification and compression is ready for transport and storage [3]. The oxy-fuel combustion of biomass could provide a CO 2 capture method that would avoid further CO 2 emissions, besides reducing costs and efficiency penalties [4]. Although some problems might arise from the use of biomass, such as milling or transportation costs, these could be overcome if adequate consideration were given to the fuels, design and operating conditions of burners and boilers.…”

Comparison of CO2 Capture Approaches for Fossil-Based Power Generation: Review and Meta-Study

“…However, without N 2 , some other gas must be used as a diluent, and usually captured CO 2 downstream is recycled to the combustor for this purpose. Although there are many technical challenges with this approach, pilot plants up to 30 MW have been constructed [40], making them less mature than IGCC, but still feasible for large-scale implementation in the relatively near term. As will be shown in this work, oxyfuels have lower GHG emissions than post-combustion solvent-based capture, and are more cost effective on average, although there is high variability from study to study.…”

Fundamental Experiments of Coal Ignition for Engineering Design of Coal Power Plants

“…Ultra supercritical power plants have been developed for improvement of power efficiency [13]. Oxy-fuel combustion technology is being pursued for carbon capture and storage [14]. Further reduction of the environmental load, such as NOx reduction, is also still required [15].…”

“…Estimated results reproduced the tendency. Recently, development of oxy-fuel combustion technology has been particularly active using pilot-scale plants [14]. Fundamental studies of ignition for oxy-fuel combustion have also been promoted [9,31,32].…”
