“…For all the studied coals, the burnout obtained with the mixture 79%CO 2 -21%O 2 is lower than that reached in air. This result is in agreement with the findings of other researchers using other experimental devices [23,24,25,26]. When N 2 is replaced by CO 2 , the heat capacity of the gases increases and the particle temperature during combustion is lower.…”

Oxy-fuel combustion is a GHG abatement technology in which coal is burned using a mixture of oxygen and recycled flue gas, to obtain a rich stream of CO 2 ready for sequestration. An entrained flow reactor was used in this work to study the ignition and burnout of coals and blends with biomass under oxy-fuel conditions. Mixtures of CO 2 /O 2 of different concentrations were used and compared with air as reference. A worsening of the ignition temperature was detected in CO 2 /O 2 mixtures when the oxygen concentration was the same as that of the air. However, at an oxygen concentration of 30% or higher, an improvement in ignition was observed. The blending of biomass clearly improves the ignition properties of coal in air. The burnout of coals and blends with a mixture of 79%CO 2 -21%O 2 is lower than in air, but an improvement is achieved when the oxygen concentration is 30 or 35%. The results of this work indicate that coal burnout can be improved by blending biomass in CO 2 /O 2 mixtures.

“…Although the first application of fuel burnt in high purity O 2 was as early as the 1900s for welding and cutting (Carlisle, 2004), it was not until the early 1980s that the use of RFG was proposed for the purpose of producing a CO 2 stream of high purity for use in Enhanced Oil Recovery, EOR (Abraham et al, 1982), and to simultaneously reduce the environmental impacts from the use of fossil fuels in energy generation (Horn and Steinberg, 1982). Pilot scale and demonstration plant studies were subsequently carried out by Argonne National Laboratories and the Energy and Environmental Research Corporation (Payne et al, 1989;Abele et al, 1987;Weller et al, 1985) with corresponding numerical modelling investigations (Berry and Wolsky, 1986;Wang et al, 1988). During the 1990s, the technology received further interest for greenhouse gas and NO x reduction with pilot-scale studies conducted in a project led by the International Flame Research Foundation (Woycenko et al, 1995) and in work carried out by Ishikawajima Harima Engineering to consider oxyfuel retrofits to Japanese boilers (Nozaki et al, 1997;Kiga et al, 1997;Kimura et al, 1995;Nakayama et al, 1992).…”
