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


A method for improving the performance of a radiating burner designed to be supplied during operation by means of a flow (F) comprising a mixture of air and combustible gas. The burner includes a body defining a combustion chamber and provided with an inlet for the mixture; a porous wicking agent closes off the chamber in a non-sealing manner and is arranged downstream of the inlet in the direction of flow (F) of the mixture; and a distribution grid is arranged between the mixture inlet and the wicking agent. The method includes creating an electric field in the combustion chamber by applying an electric potential difference of at least 5 kV between the wicking agent and the distribution grid.


The invention relates to a nondestructive testing device for detecting possible thickness anomalies (Ve) of a wall (P), this device comprising a sensor (
