FURNACE FOR MELTING BATCH RAW MATERIALS WITH OPTIMIZED PREHEATING ZONE

摘要

Furnace for melting batch materials comprising: a tank (3) covered by a crown (4); a combustion zone (5) provided with burners (6); an inlet (8) for charging it with the batch materials; a downstream outlet for the melted materials, the tank containing a melt (7) when the furnace is operating and the batch materials forming a batch blanket (G) that floats on the melt and is progressively melted; the furnace includes, near the charging inlet (8), an intense heating means (B), predominantly covering the width of the batch blanket, for melting a surface layer of the materials introduced and for increasing the emissivity of the batch blanket.
