“…For the treatment of the turbulence-chemistry interaction of the homogeneous reactions, the Eddy Dissipation concept (Gran and Magnussen, 1996) is recommended for modelling oxy-fuel combustion (Breussin et al, 2000;Andersen et al, 2009;Leiser, 2011). In this model, the total reaction space is subdivided into the fine structure region where perfect mixing of the reactants is assumed, and the surrounding fluid.…”

“…Therefore, available models describing these pathways are adopted for oxy-fuel combustion conditions (Breussin et al 2000). As generally accepted due to the relatively small impact of the NO x reactions on the temperature and flow field compared to the main combustion reactions, the NO x chemistry is modelled within a post-processing step (Chui and Hughes, 1996;Chui et al, 2004).…”

Oxy-fuel combustion boiler for CO2 capturing: 50 kW-class model test and numerical simulation

2010

View full text Add to dashboard Cite

A novel oxy-fuel burner was devised and integrated into a 50 kW-class furnace-type boiler system. A series of experiments was conducted to verify its feasibility for industrial applications. Additionally, numerical simulations were performed and the results validated against experimental data on the detailed physics inside the conventional-design combustion chamber. The oxy-fuel burner, with the help of gas radiation, could effectively heat the combustion chamber. The composition of the exhaust gas revealed that the sealing of the system is crucial to the achievement of high CO 2 concentrations and low NOx emissions.
