The FriendlyCoal proposal focuses on advanced boiler concepts for CO2-free hard coal fired power plants with oxyfuel technology.
The main challenge of this technology is the high combustion temperature from the combustion with pure oxygen. The commonly discussed concept to overcome this problem is the recirculation of significant amounts of CO2.
The focus of this project is to compare this commonly discussed concept with a newly invented concept - the inversely staged combustion. The project includes the burner and boiler design for an 300MWth hard coal fired power plant and in particular the testing of a newly design 3MW burner.
