Title:
METHOD FOR MELTING A COMPOSITION OF RAW MATERIALS WITH AN ARCHED BURNER
Document Type and Number:
WIPO Patent Application WO2006061530
Kind Code:
A3
Abstract:
The invention concerns a method for melting a composition of raw materials including introducing the composition in an oven to form a layer (2) at the surface of the molten pool (4). An oxycombustion burner (10) is arranged above the pool and directed towards the composition layer (2) to produce a melting front (3). Parameters of the burner are adjusted to produce a large covering flame (12) 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 (3) 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.
