Abstract
The invention concerns a method for melting a composition of raw materials including introducing the composition in an oven to form a layer () at the surface of the molten pool (). An oxycombustion burner () is arranged above the pool and directed towards the composition layer () to produce a melting front (). Parameters of the burner are adjusted to produce a large covering flame () causing an essentially radiation-based thermal transfer. Additionally, a plane containing a longitudinal section of the flame (Z-Z) and a horizontal direction perpendicular to the axis of the oven (X-X) intersects the melting front () at a height (h) included ranging between one third and half of the thickness of the composition (e). Such a method provides for a stable operation of the oven and is particularly adapted to a large-capacity oven.
