Metallurgy & Smelting

INDUSTRY OVERVIEW

Recover More Value from High-Volume Process Exhaust

Steel mills and non-ferrous smelting facilities generate enormous volumes of low-temperature flue gas throughout sintering, coking, roasting, smelting, and utility boiler operations. These exhaust streams contain valuable recoverable thermal energy but often present severe corrosion challenges due to sulfur compounds, acidic condensate, and high-humidity conditions.
Fluoroplastic-steel systems enable deeper waste heat recovery while maintaining stable operation under demanding metallurgical environments.

    A real metallurgy facility featuring:
  • ● Blast furnaces
  • ● Sintering plants
  • ● Smelting furnaces
  • ● Flue gas ducting
  • ● Heat recovery systems
  • ● Large industrial steel structures
