DESIGN
- Higher superstructure at the entrance zone – crown execution
- Flat cover blocks at downstream zones
- Optimally calculated distances from the furnace centreline to each forehearth to minimise the risk of glass flow short-circuiting and to optimise the forehearth entrance temperature
- Differentiated control sections for accurate temperature adjustment
- Width individually customised depending on total pull, required temperatures and residence time
- Length individually customised to available space, number and arrangement of forehearths
- Depth individually customised depending on total pull, required temperatures, residence time and glass colour
- Several natural or forced cooling systems are available which are adapted to the design of each distributor:
- Radiation openings
- Direct cooling system (individually adjustable)
STEEL WORK
- Assembly of the forehearths follows conventional design
- Substructure refractories are enclosed in steel casings
- Braced frames support the superstructure
- Designed to meet modern technical requirements to achieve optimal thermal homogeneity combined with minimum energy requirement
- Channel blocks of zircon mullite, fused cast AZS or alumina material
- Forehearth superstructure in sillimanite material and premium insulating refractory materials
- Constant air/gas Ratio
- Safety switch-off system (in accordance with DIN EN 746-2)
- Automatic lambda control (optional)
- Preassembled skids for easy installation including pipework
- Used at distributors and forehearths (GCS® Series 200 and 301-advanced)
COOLING EQUIPMENT FOR DISTRIBUTORS AND FOREHEARTHS
- Customised cooling fan layout
- Alternatively two central cooling air fans for all air cooling systems, one in operation and one as stand-by
- Radiation and/or flue gas openings can be operated manually or automatically
- Fully automatic temperature control loops in each zone
- Spout heating can be controlled manually or automatically
- Different types of temperature measurements (thermocouples or pyrometers) are available for each zone
- Grid-measurement in equalising zone with K-factor calculation, according to Emhart 9 point formula
- All measuring and control instrumentation housed in a completely assembled and wired control panel
- “Blind” connection possible for the subsequent installation of an additional forehearth
- Opening for the glass level measuring device
- Tailor-made for optimised pre-conditioning of the glass
- Different cooling systems are available and adapted to the specific requirements
