Conventional power generation in the UK faces a significant challenge in the face of decarbonising and maintaining a reliable, secure and cost effective electricity supply. The requirement for fossil-fuel based systems to integrate smoothly with CCS technologies has led to the realistic consideration of oxyfuel based generating plant for CCGT-CCS processes. For CCS to become more technically and economically feasible, it has been suggested that the CO2 scrubbing component of the CCS process will work more effectively if the CO2 concentrations in the exhaust gas were higher. Hence, enhancement of oxygen in the combustion process and the enhancement of CO2 concentration in the plant exhaust via Exhaust Gas Recycling (EGR) can dramatically increase the net efficiency of CO2 scrubbers. Whilst oxyfuel and EGR are known to be potentially very promising technologies for integration with CCGT-CCS processes, there exists a significant lack of fundamental data on the design and reliable operation of industrial burner systems with this technology.

Pictures of sulphides and trace element concentrations from ore minerals in the El Teniente porphyry Cu-Mo deposit, Chile. Samples were picked for analysis from the Natural History Museum London’s ore collection. This data contains petrological photographs and trace element concentration of ore minerals. This data was collected as part of the TeaSe consortium NERC grant in order to determine the concentration and hosting of critical and precious metals in various types of ore deposits and barren rocks from different geological environments. This data was collected and interpreted by researchers at Cardiff University.
This poster on the UKCCSRC Call 1 project Oxyfuel and exhaust gas recirculation processes in gas turbine combustion for improved carbon capture performance was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-26. This research is concerned with oxyfuel combustion in gas turbine applications, in particular concentrating on the use of modern swirl-stabilised burners. Oxyfuel is considered a particularly challenging idea, since the resultant burning velocity and flame temperatures will be significantly higher than what might be deemed as a practical or workable technology. For this reason it is widely accepted that EGR-derived CO2 will be used as a diluent and moderator for the reaction (in essence replacing the role of atmospheric nitrogen). The key challenges in developing oxyfuel gas turbine technology are therefore: • Flame stability at high temperatures and burning rates. • The use of CO2 as a combustion diluent. • Potential for CO emission into the capture plant. • Wide or variable operating envelopes across diluent concentrations. • Differences in the properties of N2 and CO2 giving rise to previously unmeasured flame heat release locations.
