In a combustion process, especially one used for melting glass, the delivery of fuel is ensured by an apparatus having at least one burner ( ) which is equipped with at least one injector ( ) that includes a liquid fuel delivery tube ( ) which has at least one internal wall ( ) and an injected fluid delivery tube ( ) arranged concentrically with respect to the liquid fuel delivery tube. Immediately before injecting the liquid fuel from its delivery tube, one puts it in the shape of a hollow jet basically assuming the shape of the internal wall. This has application for the reduction of NO in a glass-making oven.

Combustion process and fuel injection burner for implementing such a process

A method of regulating the calorific power of a stream of gaseous fuel of the fossil-gas type, comprising a predominant fuel gas, denoted &ldquo;A&rdquo; and flowing in a pipe. This regulation is performed, at least partly, by controlled addition of at least one fuel gas called having a calorific power greater than that of &ldquo;A&rdquo; into the stream. The subject of the invention is also its apparatus for implementation and its applications.
