Abstract

The invention relates to a liquid fuel spray injector comprising a liquid fuel intake duct and a spray fluid intake duct, said liquid fuel intake duct comprising an element perforated with oblique channels for shaping said fuel into a hollow rotating jet before ejection from said injector, characterized in that the generatrix of each of said channels makes an angle of less than 10° with the liquid fuel intake direction. The injector is intended to form part of a burner, in particular for glass furnaces. The injector serves to obtain a significant reduction of NOx.
