Abstract

Melting burner of vitreous silica for the production of massive vitreous silica by the melting of silicon dioxide particles. Propulsion jets fed with oxygen are surrounded by a plurality of oxygen-fed heating jets forming a ring. Oxygen flows around the propulsion jets and the heating jets. The front ends of the propulsion jets, which are overlapped by the front ends of the heating jets, are inclined towards the axis of the melting burner.
