“…Oxy-fuel combustion technology, where CO 2 replaces nitrogen as diluent to control the flame temperature, holds a great promise of increased energy efficiency, reduced nitroxide pollution, , and an opportunity for carbon sequestration. , In many studies the standard combustion mechanisms are presumed to be valid at CO 2 -reach conditions for data interpretation and modeling the flame composition, , or turbine design . Although several kinetic models for the methane combustion mechanism were developed, none of them was designed for oxy-combustion specifically. , These mechanisms involve a large number of elementary reactions, and some of them may be altered by the presence of carbon dioxide in large concentrations and high pressures …”
