DESIGN
- The superstructure is designed for optimal combustion system performance
- Modular construction system to achieve optimal thermal homogeneity combined with minimum energy output
- Used for up to 50 t/d
- Typical length starts at 10 ft
- Standard width from 16” to 26”
- Standard glass depth of 4” to 6”
- T-type, F-type or Y-type for tandem production available, depending on machinery layout
- Radiation openings are provided in the forehearth superstructure at each cooling zone
- Openings are sized according to the required cooling and are located at the beginning of each zone
- The heat radiation through the opening can be varied by adjusting the damper
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
- Fast and effective cooling with radiation openings
- Refractory can be designed for additional stirrers, VARI-DRAIN® or forehearth boosting
