Abstract

LIQUEFYING OF PULVERULENT BATCH MATERIALS (E.G GLASS BATCH) IS CARRIED OUT IN TWO STAGES. THE FIRST STAGE UTILIZES EXTENDED GAS/SOLID CONTACT TO HEAT THE MATERIALS TO AN INTERMEDIATE TEMPERATURE, AND MAY RECOVER WASTE HEAT. THE SECOND STAGE RAPIDLY LIQUEFIES THE MATERIAL IN A CAVITY LINED WITH THE BATCH MATERIAL AND MAY EMPLOY SUBSTANTIALLY NITROGEN- FREE HEAT SOURCES. ANOTHER ASPECT INVOLVES MAINTAINING A WET CONDITION IN THE FIRST STAGE TO ENTRAP PARTICULATES.
