“…The resulting flue gas is primarily CO 2 , with trace amounts of oxygen and other gases that can be flashed off during the compression of the CO 2 . A major part (70-80%) of the CO 2 -rich exhaust gas is recycled back to the boiler to control the combustion temperature (Buhre et al, 2005). The remaining part of the flue gas, (consisting mainly of CO 2 and water vapour and small quantities of Ar, N 2 , NO x , SO x and other constituents from air leakage and fuel) is cleaned, compressed and transported to storage or another suitable application, such as enhanced oil recovery (EOR).…”

“…The role of coal as an energy source has attracted renewed interest due to the stability of its supply and its relatively low cost, which will probably guarantee its inclusion in the energy mix in the foreseeable future [1]. Until renewable energy sources can reliably produce significant amounts of energy, the immediate energy demand is likely to be met by conventional fossil fuel combustion, such as coal.…”

The ignition temperature, burnout and NO emissions of blends of a semi-anthracite and a high-volatile bituminous coal with 10 and 20 wt.% of olive waste were studied under oxy-fuel combustion conditions in an entrained flow reactor (EFR). The results obtained under several oxy-fuel atmospheres (21%O 2 -79%CO 2 , 30%O 2 -70% CO 2 and 35%O 2 -65%CO 2 ) were compared with those attained in air. The results indicated that replacing N 2 by CO 2 in the combustion atmosphere with 21% of O 2 caused an increase in the temperature of ignition and a decrease in the burnout value. When the O 2 concentration was increased to 30 and 35%, the temperature of ignition was lower and the burnout value was higher than in air conditions. A significant reduction in ignition temperature and a slight increase in the burnout value was observed after the addition of biomass, this trend becoming more noticeable as the biomass concentration was increased. The emissions of NO during oxy-fuel combustion were lower than under air-firing. However, they remained similar under all the oxy-fuel atmospheres with increasing O 2 concentrations. Emissions of NO were significantly reduced by the addition of biomass to the bituminous coal, although this effect was less noticeable in the case of the semianthracite.

“…The current mainstream approach to achieving this goal is to curb the emission of CO 2 by capturing at point-sources and geologically storing it. So far, three industrial combustion processes have been identified as the point-sources for carbon capture: [3][4][5][6][7][8][9][10] pre-combustion, postcombustion and oxy-combustion. Although significant progress has been made over the past decades, today's carbon capture technologies (capture, compression and storage or collectively CCS) are still too expensive, cumbersome and energy intensive.…”
