A New Combustion Method in a Burner with Three Separate Jets

Autor: Mohamed Ali Mergheni, Toufik Boushaki, Mohamed Mahdi Belhajbrahim, J.C. Sautet

Oxy-flames from burners with separated jets present attractive perspectives because the separation of reactants generates a better thermal efficiency and reduction of pollutant emissions. The principal idea is to confine the fuel jet by oxygen jets t
