Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner

Journal of Thermal Science and Technology, 2018
Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner was studied. A diffusion flame was stabilized in the gap between opposed ports ejecting fuel and oxygen gases, and its thickness which depended on the gap distance between burner ...

Study on flame stability in oxygen-enriched ammonia/N2/O2 laminar diffusion flame

Nihon Kikai Gakkai ronbunshu, 2018
Ammonia is regarded as one of the alternative fuels because CO2 is not emitted during the combustion process of ammonia. The physical properties of ammonia are suitable for transportation and storage as a “hydrogen carrier”.
