    摘要： The present invention relates to a melter assembly (1) for melting solid raw batch material, which comprises a submerged combustion melter section (3) and an afterburner section (5), wherein the submerged combustion melter section is designed to contain the melt bath (4) at a maximum melt level (4′) and comprises at least one submerged combustion burner (21) and a melt outlet (9), and wherein the afterburner section (5) is designed as a space contiguous with, and in continuity of, the internal space defined by the submerged combustion melter section (3), and arranged over the maximum melt level (4′) of the submerged combustion melter section (3). The afterburner section (5) is dimensioned such that the gases escaping from the melt bath (4) remain for at least 2 seconds at a temperature of at least 850° C. in said afterburner section (5), prior to being evacuated to the environment. The invention also relates to a process making use of such melter assembly (1).

    摘要： The present invention relates to a process for melting solid batch material, comprising the steps of introducing solid batch material into a melter, and melting the solid batch material in the melter by submerged combustion and subjecting the melt to a flow pattern which when simulated on a computer by making use of common fluid dynamic equations shows a substantially toroidal melt flow pattern in the melt, comprising a major centrally inwardly convergent flow at the melt surface, the central axis of revolution of the toroid being substantially vertical. The invention further relates to a melter assembly for carrying out the process. The toroidal melt flow pattern is achieved by suitable arrangement, angle and spacing of multiple submerged combustion burners in the floor of the melter.
