Abstract:
1. A method of melting a batch of raw vitrifiable materials, comprising the following steps: a batch of raw vitrifiable materials is introduced into a furnace in a charging direction (D) parallel to a longitudinal central axis (X-X) of the furnace, distributing the batch substantially continuously and uniformly over a defined charging width (L), so as to form a layer of the batch on the surface of the melt; and an oxyfuel burner is placed above the melt in a vertical plane (P) including the axis (X-X) of the furnace, the burner being directed toward the batch layer so as to create a melting front of the batch present in the layer, the melting front being symmetrical with respect to the plane P, adjusting the parameters of the burner, carried out so that:
