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