Sixth Meeting of the SCO2 Oxy-Combustion Working Group
At the first meeting, computational modeling results were presented by Dr. Pete Strakey of NETL. Dr. Jacob Delimont from Southwest Research Institute gave a presentation at the second meeting on recent efforts to design, build, and test an oxycombustor in the existing Sunshot loop at Southwest Reasearch Institute. At the third meeting which took place in April we had two presenters: Dr. Wenting Sun from Georgia Tech and Dr. Subith Vasu from the University of Central Florida, who both presented progress associated with University Turbine Systems Research awards to investigate autoignition delay of syngas and natural gas in sCO2 oxycombustion conditions. Last August we heard a presentation from Dr. Lee Shunn from Cascade Technologies, Inc. At the UTSR Workshop in Daytona Beach last November, we had a session to review all of the ongoing NETL-funded projects in sCO2 oxycombustion. In July, we had a presentation from Dr. Matthias Ihme from Stanford University titled “Thermostructural Analysis and Numerical Modeling for Scalar Mixing and Combustion at Supercritical Conditions”.
At this sixth meeting, Dr. Wenting Sun joined us from Georgia Tech to discuss some of the final findings from the UTSR project that just came to a close at the end of September. The title of today’s talk is “Investigation of Methane and Syngas Autoignition for Supercritical CO2 Power Cycles".
As a reminder the mission of this working group is to promote a technical dialogue on the subject of oxy-combustion for direct SCO2 power cycles to identify priority technology gaps and track progress on addressing technical challenges.
Conclusions – CH4
