HORN system for supporting the glass melting process

The addition of an electric heating system can greatly support the glass melting technique. Beside concentrated regulation of the glass flow the melting output is increased due to the Joule effect within the glass. Depending on the existing situation or the customer’s request the boosting system can be manufactured for melting boosting with lateral and bottom electrodes, as barrier boosting or as throat boosting. A combination of these systems is also possible.

Key:

1. Boosting/ Sidewall electrodes
2. Barrier boosting/ Bottom electrodes
3. Throat boosting

When designing the boosting system HORN applies the latest technical aids as well as its vast experience of boosting system installations. Melting boosting and barrier boosting mainly increase melting pull and quality by concentrated regulation of the convectional flow. The purpose of throat boosting is concentrated regulation of the convectional flow. The purpose of throat boosting is concentrated heat input in the throat in order to prevent “freezing” of the glass in this zone, mainly during the starting stage with darker glass colors.

The boosting systems can be equipped as one-phase or multiple-phase systems. Depending on the situation continuous thyristor-controlled system or a continuously working transformer may be used.

When designing such systems HORN takes into account both optimum operational function and optimum integration in the existing electric net-work.

All boosting systems supplied by HORN are fully installed and commissioned.
