Abstract
The injector comprises a duct (31) through which a liquid fuel which forms a film lining its wall, and an atomizing fluid, are transmitted to its downstream part, from where the fuel is sprayed, forming a mist with the atomizing fluid. The downstream part has, from the duct (31) towards the free end of the injector, a chamber (32) for destabilizing the film which has a cross section that is larger than that of the duct, a throat (33) for detaching the film extending the destabilization chamber and having a cross section that is smaller than that of this chamber, and a spray orifice (34) which is open at the end of the injector, into which the throat opens, and which has a larger cross section. Use: heating furnaces, especially glass furnaces.
