%X A review of the projects that are developing the oxyfuel coal combustion technology  around the world has been undertaken based on their available progress. The evaluation  carried out is focused on different projects, such at small and large pilot scale as  demonstration projects. All these studies and projects undertaken and in process show  that fundamental understanding of the principles and basis of oxycoal combustion with  flue gas recirculation have been well established during the past 20 years of R&D  activities, but there are still some gaps in knowledge that are trying to be solved. The last  objective of all of these projects is to demonstrate the oxyfuel technology in a commercial  scale, taking into account another competitive alternatives, such the post-combustion for  retroffiting existing power plants or the IGCC option. he conclusion of this study is that the  oxyfuel combustion technology is suitable for retrofitting pf boilers and achieves clean coal  combustion, lowering NOx, increasing SOx removal, possibly lower mercury emissions  and obtaining a CO2 concentration for sequestration
