Task 1.4: Oxy-fuel technologies
The overall objective of the task is to provide solutions for Oxy-fuel combustion and Flue Gas Recirculation based CO2 capture technologies
Task 1.4 contributes to the overall objectives of BIGCCS through:
- The installation of the high pressure oxyfuel combustion facility (HIPROX), a powerful experimental platform for the creation of new oxy-fuel burners and combustors, as well as an international site for testing equipment through the EU research infrastructure sharing program ECCSEL.
- The conception and study of thermal power cycles with exhaust gas recirculation (EGR or FGR) to reach concepts with fuel-to-electricity penalty less than 6 percentage points compared to state-of-the-art fossil fuel power generation.
- The collaboration with research groups: DLR (Stuttgart, Germany) and Målardalen University (Sweden) strengthening the international cooperation within the field of CCS.
- The study of innovative burner and flame technologies, such as MILD combustion, providing crucial knowledge and a basis for technology breakthroughs.
Some Task 1.4 achievements:
- Fully operative high pressure oxy-fuel combustion facility (HIPROX).
- Demonstration of the FLOX® concept for flue gas recirculation (FGR) cycles (DLR/Stuttgart).
- A supplementary fired unit cycle configuration that has achieved an efficiency penalty less than 6 %.
- Benchmarking evaluation of Exhaust Gas Recirculation (EGR) technologies applied to post-combustion cycles.
- Spin-off of a pilot scale oxy-fuel gas turbine project OXYGT with Siemens, NEBB Engineering and Lund University.
- Characterization of heat radiation and soot formation in oxy-fuel flames.
- New fundamental knowledge acquired in Laser Induced Incandescence (LII) flame diagnostic.
- Fate of CO and NOx and in oxy-fuel and post-combustion in FGR cycles.
- A PhD on pressurized oxy-coal cycles started in 2011.
- Several papers in international peer reviewed journals (Journal of Energy, Applied Energy, Applied Physics B: Lasers and Optics, Experimental Thermal and Fluid Science, Energy Procedia)
