Hot air duct

Post on: 12-12-2023

With the trend of saving energy and reducing carbon footprint in production, more and more cement plants are equipped with heat recovery systems from clinker cooling to generate electric power. The refractory layer for hot air ducts is designed to be thin so it has high abrasion resistance from clinker dust and has insulation properties to reduce heat loss. Suitable materials to use are heat-resistant and abrasion-resistant grout Novaflex-1000H, Novaflex-1200H, for patching or gunning onto the hex-mesh layer welded to the inner shell of the hot air duct, or Novacast-60AZ, Novagun-60AZ for casting or gunning into areas with sufficient thickness according to design.
