FOREHEARTH GCS® SERIES 200

GENERAL

 

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

 

DIMENSIONS
  • 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
  • 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

 

REFRACTORIES
  • 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

 

CORA® MIXTURE HEATING SYSTEM
  • 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

 

MEASUREMENT AND CONTROL SYSTEM
  • 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

FEATURES

  • Fast and effective cooling with radiation openings
  • Refractory can be designed for additional stirrers, VARI-DRAIN® or forehearth boosting
