The German Environment Agency stated in 2023 [1], based on the recent report from the International Panel on Climate Change (IPCC), that “Expectations about the role of carbon capture and storage (CCS) in meeting the global temperature target of 1.5 °C are high”. This statement emphasises the critical role of CCS to meet climate targets. Of the various approaches to CCS, this book focuses on one route, oxy-fuel combustion. It presents the achievements and findings of a 12-year research initiative, funded by the German Research Foundation (DFG), on solid fuel combustion in an O2/CO2/H2O atmosphere (oxy-fuel combustion). The primary aim of the research was to understand the fundamental processes and mechanisms involved in order to determine the decisive differences arising from the replacement of air as the oxidising agent by an O2/CO2 mixture. Research and development activities led by the industry are focused primarily on system-level aspects demonstrating the feasibility of the concepts and to enable rapid implementation. Vattenfall for example, driving large scale oxy-fuel combustion, operated a 30 MWth boiler from 2008 to 2014 to specifically prove the viability of flue gas cleaning, the combustion process itself and the related controls. Due to changes in the political landscape, the focus of the power sector in Germany has shifted away from oxy-fuel to a mix of renewables and hydrogen-fueled power plants. Nowadays, the pace in oxy-fuel combustion development is therefore being set by industries that face the additional problem of unavoidable product-related CO2 emissions, such as the cement and lime industry. These industries are under particularly intense pressure to achieve future CO2 reduction targets. For example, a large-scale oxy-fuel-fired pilot cement plant is scheduled to begin operations in Mergelstetten (Germany) in 2026 and oxy-fuel lime shaft kilns are already offered on the market. With larger scale operations and feasibility studies, fundamental aspects often remain unexplored, yet they are crucial for a reliable design and the detection of failures in case of damage. Therefore, to address open questions around oxyfuel combustion of solid fuels, a research consortium (CRC/TRR129 “Oxyflame”) between RWTH Aachen University, Ruhr-Universität Bochum, and Technische Universität Darmstadt was established and funded by the DFG. Oxyflame got started in October 2013 and ended in June 2025. This book is of interest for scientists, advanced students interested in combustion, and development engineers in the industry. Readers are encouraged to refresh their understanding of the fundamental principles of oxy-fuel combustion.
