Combustion process and burner using atomized liquid fuel

摘要

The combustion process is for melting glass. Feeding of a fuel is assured by a burner equipped with at least one injector (1). Each injector is made up of a first conduit (2) fed with liquid fuel presenting at least one internal wall (25) and a second conduit (3) fed with an atomized fluid arranged concentrically with respect to the conduit fed with liquid fuel. Immediately before the injection of the liquid fuel into its feed conduit it is put into the form of a hollow jet essentially adopted to that of the internal wall. The burner used in this combustion process and its use for reducing NOx emissions are also claimed.
