Oxyfuel combustion and carbon storage

Combustion of carbon-based fuels remains an important energy generation method. In this context, it remains important to reduce harmful atmospheric combustion emissions, including carbon dioxide (CO2), carbon monoxide (CO), nitrous oxides (NOx) and sulphur oxides (SOx). One promising method is Moderate or Intense Low-oxygen Dilution (MILD) oxyfuel combustion. In contrast to common combustion technologies using air and fuel for the reactants, oxyfuel combustion involves oxygen (O2) only, without the nitrogen from the air, diluted in CO2 from the exhausts, burning with the fuel. In MILD combustion, the oxidant (air or O2/CO2) is preheated above the self-ignition temperature, with both the oxidant and fuel injected at high speed. This results in stable combustion that produces little NOx and negligible unburnt fuel. The combination of MILD and oxyfuel combustion techniques is expected to reduce atmospheric pollution and maintain high thermal efficiency. The resulting combustion system can also be easily coupled to a separation unit to remove CO2 from the product stream, facilitating carbon capture and storage.

These case studies are only several of our projects. There are many more types of opportunities and case studies. If you'd like to discuss partnering or sponsoring a research project in Turbulent Combustion Modeling or would like more details:
