Thermal Ceramics Kaolite 2000-HS Insulation Castables
Categories: Ceramic; Oxide

Material Notes: Kaolite 2000-HS is a general-purpose, lightweight castable for use up to 2000°F (1093°C). It maintains excellent volume stability throughout its temperature use range. This is an excellent advantage for applications where strength and low thermal conductivity are required.

Features:

  • Light weight and low thermal conductivity reduce both the quantity of heat storage and heat transfer producing significant savings in furnace fuel consumption
  • Lower densities reduce the amount of supporting furnace steelwork required and provide more insulation with a thinner lining.
  • Applications:

  • Backup insulation in two component linings in petrochemical process units
  • Hot face lining in ductwork from waste heat recovery boilers and process unit
  • F.C.C.U. linings - regenerator.
  • Hydrogen or reducing atmosphere linings
  • Radiant section in steam flood generators.
  • Hydrogen or reducing atmosphere linings.
  • Steam flood generator convection sections and target walls
  • Cat cracker regenerator linings
  • Petrochemical applications
  • Information provided by Thermal Ceramics
