Demonstration of an oxyfuel combustion system

Doosan Babcock is aiming to develop a competitive oxyfuel firing technology suitable for full plant application post 2010, and is taking a phased approach to the development and demonstration of oxyfuel technology. Doosan Babcock is leading a number of UK Government supported collaborative projects that are developing oxyfuel combustion technology. The "Fundamentals and Underpinning Technologies" project aims to develop a competitive oxyfuel firing process based on the integration of well proven and innovative power plant design components, addressing critical technology gaps such as combustion fundamentals, furnace design and operation, novel flue gas purification technologies and generic process issues. The "Demonstration of an Oxyfuel Combustion System" project aims to demonstrate an oxyfuel combustion system of a type and size (40MW(t)) applicable to new build and retrofit advanced supercritical boiler plant. These two projects are discussed in the paper and preliminary results from pilot-scale testing undertaken in the first of these are presented. (C) 2008 Elsevier Ltd. All rights reserved.
