INJECTOR INJECTING A HOLLOW JET OF LIQUID FUEL

摘要

The invention relates to an injector for spraying liquid fuel, comprising a liquid fuel supply duct and an atomization-fluid supply duct, said liquid fuel supply duct comprising an element pierced with oblique passages to bring said fuel into the form of a swirling hollow jet before it is ejected from said ejector, the generatrix of each of said passages making an angle of less than 10° with the direction in which the liquid fuel is supplied. The injector is intended to form part of a burner, particularly to be fitted to glass-making furnaces. The injector allows an appreciable reduction in NOx.
