ELECTRIC BOOSTING SYSTEMS

GENERAL

Electric furnace boosting systems have been effectively installed within the glass industry since 1970. With its boosting systems, HORN® provides different boosting applications to meet the challenging demands during the glass melting process. The individual electric boosting systems are tailor-made for each furnace regarding the required effect on the melting process. Each boosting system is unique and contributes to the most efficient and flexible operation of the furnace.

Generally  the  furnace  is  designed  for  an  input  of  additional electric energy to melt up to 20% of the total output. Due to economic reasons, a percentage of approximately 10% is regarded as appropriate. However, it depends largely on the required effect of the electric energy on the melting process.

HORN® provides individual and tailor-made boosting systems:

  • Melting boosting with side or bottom electrodes
  • Barrier boosting
  • Refining boosting
  • Throat boosting
  • Feeder boosting

These effects are:

  • Increased melting output of the aggregate
  • Improved glass quality
  • More efficient utilisation of fossil energy sources
  • Emissions reduction   
  • More stable and flexible production
  • Accelerated re-melting processes in case of colour changes
  • Quicker change between the different products

 

The HORN® electric boosting system is a complete stand-alone system ready for operation and consists of:

  • Electrodes and water-cooled electrode holders along with accessories, e.g. piping and cables
  • Transformer units, e.g. single-, two-, or three-phase aggregates or thyristor controlled transformers
  • Fully automatic instrumentation and control system
  • Power and control cables
  • Cooling water cycle with flow control station

 

When designing the boosting system HORN® applies the latest technical aids as well as its comprehensive experience in boosting system installations. The effect of the boosting system can be simulated via modern software on computers before starting with the detailed planning and manufacturing of the equipment.

FACTS

  • Increased melting output and stabilisation of the glass flow
  • Reduced emissions
  • Increased glass quality
  • Retroactive installation in melting ends already operating
  • Prevention of critical situations in case of pull change
  • Increased re-melting process
  • Computer Modelling – establishing optimal dimensions and positioning of the boosting system
