Glass melting and/or refining furnaces are improved by inducing helicoidal motion of introduced glass composition particles to increase the particle dwell time

摘要

Glass melting and/or refining furnace improvement involves inducing helicoidal motion of introduced glass composition particles (6) to increase the particle dwell time. Glass melting and/or refining furnaces are improved by increasing the dwell time of particles of the glass composition (6) introduced into the furnace by making them describe a helicoidal trajectory about the main glass withdrawal direction between the charging region (9) and the glass withdrawal region (4).
