Description

The HORN® Forehearth GCS 200 system works with Centreline Radiation Cooling and represents a today’s most advanced technology in the areas of forehearth design for low and medium capacity and accurate temperature adjustment. The refractory structure design is up to date modern construction employing all today’s techniques to achieve optimum thermal homogeneity combined with minimum energy requirement.

High quality refractory material is used for channel blocks. All channel block joints are backed up with zircon mullite split tiles and are surrounded with suitably graded insulation material.

The roof blocks of the superstructure in the cooling sections are of a special shape to ensure the best possible heating of the glass. The blocks are shaped like flat roof blocks with the central portion lowered towards the glass surface. The lowered part of the roof block provides a turbulent waste gases coming from the burners. The heating of the outer edges is also assisted by reflected flame radiation, due to the inclined design of parts of the roof block. This design provides a reduction in the temperature difference in the glass between the centre and the outer edges of the channel.

The combustion system is characterized by its long-lasting reliability in any operational situation and includes the constant gas/air ratio CORA system for stable firing by small pencil burners along the whole length of the forehearth.

Centreline Radiation Cooling  

For additional temperature homogenization there are one or more radiation cooling opening foreseen in the superstructure cover blocks of the cooling zone. This opening is sized and located according to the cooling requirement. The actual heat loss through the opening is varied by the movement of the damper block which is used to open or close the opening.
