A combustion method for melting glass in which two fuels of the same nature or different natures are fed into a fusion furnace at two locations remote from each other for distributing the fuel to reduce NOx emissions. The combustion air is supplied at only one of the locations. In a method for operating a glass melting furnace, the fuel injection is distributed to reduce NOx emissions. The furnace includes a melting vessel for receiving the glass to be melted and containing a bath of molten glass, walls defining the furnace, a hot combustion air inlet, a hot smoke outlet, at least one burner for injecting a first fuel, and at least one injector for injecting a second fuel. The injector has an adjustable flow complementary relative to the flow to the burner so that up to 100% of the totality of the first and second fuels used may be injected.

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.
