Abstract
Oxy-fuel combustion is a promising strategy to minimize the environmental impact of combustion-based energy conversion. Simple and flexible tools are required to facilitate the successful integration of such strategies at the industrial level. This study couples measured residence time distribution with chemical reactor network analysis in a close-to-reality combustor. This provides detailed knowledge about the various mixing and reactive characteristics arising from the use of the two different oxidizing streams.
Highlights
The combustion of fossil fuels plays an essential role in power generation, owing to its high power density and flexibility
The Residence Time Distribution (RTD) is the probability of how long fluid elements remain inside a continuous process
A thorough investigation of oxy-fuel combustion is crucial in order to understand this technology, and flexible modeling strategies must support the interpretation of experimental results
Summary
The combustion of fossil fuels plays an essential role in power generation, owing to its high power density and flexibility. Is identified as a key strategy to mitigate combustion-induced climate change [1,2,5,6,7] It allows for exploitation of the benefits of carbon-based energy conversion with minimal changes and high retrofitting possibilities. Oxy-fuel combustion is a promising technology that significantly enables CCS by leading to an exhaust gas mainly composed of carbon dioxide (CO2 ) and water vapor [8,9]. Such a concept, though exhibiting undeniable advantages, must be carefully studied in order to fully understand the hidden aspects required for successful integration at the industrial level
