Title
(DE) Verfahren und Installation zum Glasschmelzen
(EN) Method and installation for melting glass
(FR) Procédé et installation de fusion de verre
Abstract
(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 oeuvre dudit procédé de fusion.
