Title
(EN) GLASS-MELTING EQUIPMENT AND PROCESS
(FR) INSTALLATION ET PROCEDE DE FUSION DE VERRE
Abstract
(EN) Process for melting glass in which, during a first phase, use is made of flow DO1 of an oxygen-rich oxidizer for the combustion of a fuel in the combustion chamber 100, the oxygen-rich oxidizer being preheated by heat exchange with an oxidizer that is less rich in oxygen, said less rich oxidizer being heated via heat exchange with the flue gases generated, and during a second phase, use is made, as oxidizer, of a reduced flow DO2 of the oxygen-rich oxidizer and also a flow DA2 of the heated less rich oxidizer; and equipment for the implementation of said melting process.
(FR) Procédé de fusion de verre dans lequel, pendant une première phase, on utilise un débit DO1 d'un comburant riche en oxygène pour la combustion d'un combustible dans la chambre de combustion 100, l'oxydant riche en oxygène étant préchauffé par échange thermique avec un oxydant moins riche en oxygène, ledit oxydant moins riche étant chauffé par échange thermique avec les fumées générées, et pendant une deuxième phase, on utilise comme comburant un débit réduit DO2 de l'oxydant riche en oxygène ainsi qu'un débit DA2 de l'oxydant moins riche chauffé; et installation pour la mise en œuvre dudit procédé de fusion.
