Tuyere Stocks

Design Features Of Tuyere Stock

  • Minimizing of heat loss of process temperature due to optimized thermal insulation (Thermoblocker)
  • Pressure rating up to 6 bar.
  • Service temperatures up to 1550°C.
  • Nominal sizes up to 600 mm (24 inch).

The Design Guarantees

  • Extended operational life of the Tuyere Stock due to thermal insulation which reduce the thermal stresses.
  • Reduced operating costs due to decreased heat loss of process temperature.
  • Increased safety due to reduced surface temperature.
