Glass in the form of fibres has found wide and varied applications in all kinds of industry.
Its composition and production method dependant on the intended use. Continuous strand methods are used for application such as strengthening or stiffening thermo-plastics and polypropylene and the crown method is used for applications such as heat and sound insulation in buildings, and domestic appliances.
Fibre, whether formed using the Crown or Continuous strand method, has a common need for a stable production temperature. In recent years that need for stability and accuracy of temperature control has become more and more prevalent. In addition BH-F longitudinal cooling in the pre-bushing section allowed fibre producers to increase production tonnage's using the same forehearth footprint.
We are able to meet these needs head on with the
BH-F 400 and 4000 series forehearth system which has been supplied to fibre producers around the globe. Our tailor made solutions are the result of an evolution of glass conditioning products, which allow today's fibre producers to meet today's production requirements. Within our range of forehearths we have incorporated specific components for fibre production such as condensate trap exhausts.
The forehearth combustion equipment can be supplied with either
BH-F VSF air gas combustion systems or
BH-F oxy-gas combustion systems allowing utilisation of spare oxygen capacity from the furnace. The use of an oxy gas combustion system has an additional advantage in reducing the amount of volatilisation experienced with some of today's glass types.
