ABSTRACT:
As a rule a melt-good consisting of glass fragments and glass batching will be moist and tend to agglomerate and bridge-form when being preheated in a plate heat-exchanger 10 whereby the travel of the melt-good through the plate heat-exchanger 10 may be blocked. To remedy these drawbacks, the preheating stage is preceded by a drying stage of the moist melt-good. For that purpose, in the intake zone of the melt-good, the moisture of the melt-good is evaporated by means of a separate feed of hot heating gas into the already cooled flows of heating gas. At the same time the heated melt-good is made to pass through cavities 12 through which the steam may escape to the outside. Thereby condensation shall be precluded and only fluid or friable melt-good arrives at the preheating stage.
