The current work investigates experimentally the combined effects of oxy-combustion and partial premixing of the oxidizer (O2 plus CO2) and the fuel (compressed natural gas, CNG) on flame stability considering new burner configuration, namely perforated plate burner. The work explains and quantifies the limits of flammability, visual flame appearance as well as the extinction mechanisms and the visual...
Concerns about global warming have encouraged the interest in hydrocarbon combustion techniques that allow easy capture of carbon dioxide. One technique for achieving this objective is through the use of pure oxygen instead of air for combustion or what is called oxy-combustion carbon capture technology. The main goal of the manuscript is to study flammability limits, visual flame appearance and exhaust...
In this work, two sets of experiments were performed including air and oxy-combustion premixed flames stabilized over a perforated-plate burner. A set of experiments was performed considering air–fuel combustion in order to identify a range of equivalence ratio for stable flame operation at fixed oxidizer Reynolds number and over a range of premixing ratio (namely 7, 25, 45, 67 and 128). Also, effects...
