摘要 |
<p>A glass melting tank has a melting chamber 11, a shallow uniflow conditioning chamber 50, a shallow refining chamber 51 and a riser chamber 14 between the melting chamber and refining chamber. Heat is input to glass in the riser chamber 14 by electrodes 25 located centrally in the riser chamber near the base 26 of the riser chamber. Temperature sensors 24,32 sense the temperature entering the riser chamber through a throat 23 and near the base of a downstream wall of the riser chamber and the heat input is controlled to produce torroidal flow in the riser chamber. <IMAGE></p> |
