Chamber furnace

meltingelectricfor glass working

General description
Furnaces designed for melting and conditioning glass for tableware production (plates, bowls, stemware, etc.). Suitable for manual and automatic forming lines; furnace type selection depends on daily output and process automation.

Glass types

• Soda lime glass
• Barium glass
• Barium & lead glass
• Lead crystal

Glass colours

• Flint
• Extra flint
• Green (antique glass)
• Coloured glass

Design
Recuperative furnaces with metal recuperators are commonly used and are appropriate for capacities up to approximately 40–50 tpd. For larger installations, regenerative furnace designs offer higher thermal efficiency and better fuel economy.

Design can include

• Gathering bays, with manual gathering or robotic systems
• Forehearths and feeders for automatic production lines

Equipment and components
Options include colouring forehearths for special glass runs, electric boosters and air bubbling as thermal barriers to manage temperature and pull variations. Stirring mechanisms in gathering bays are recommended to reduce bubble defects.
