This HORN distributor channel design is an up to date, modern construction employing all today’s techniques such as high quality refractory material, direct and indirect air cooling systems, as well as radiation cooling equipment, to achieve optimum thermal homogeneity combined with minimum energy requirement.
The superstructure modules of the distributor are designed to obtain the maximum effect from the combustion system and the cooling system on the glass. The combustion system is characterised by its continuing reliability in any operational situation and includes the constant ratio CORA system for an optimum air/gas mixture.
The cooling system is designed to obtain high radiation cooling before the glass flows into the forehearth’s entrance. In special cases, e.g. short distance or high pull, direct and/or indirect air cooling systems are applied.
- width from 500 mm up to 1.500 mm (> 1.300 mm with restricted entrance)
- length individually adapted to the available space and the number of connected forehearths
- differentiated control sections for accurate temperature adjustment
- optimally calculated distances from the furnace centerline to each forehearth to minimize the risk of current short-circuiting and to optimize the forehearth entrance temperature
- higher superstructure at the entrance zone – crown execution
- different kind of refractory material
- narrowed entrance to minimize glass level fluctuations
- glass bath depth:
flint glass 600 mm up to 800 mm at the entrance area
green and amber glass 450 mm up to 550 mm
- graded glass bath depth to obtain the optimal residence time for each forehearth
- cooling systems:
- radiation openings
- direct cooling system (left & right at the entrance zone)
- indirect cooling system (installed as top or bottom cooling)
