· Waste-to-Energy Boilers: Superheaters in municipal waste incinerators (resists KCl/ZnCl₂ corrosion).
· Refinery Heaters: Convection sections for vacuum residue upgrading.
· Chemical Processing: Cracked gas heat exchangers in ethylene plants.
· Power Generation: SCR duct heaters for coal-fired units (handles fly ash erosion).
· Cement Plants: Preheater exhaust gas economizers.
4. Why Engineers Specify TP347 Serrated HFW Tubes:
· Zero Carbide Precipitation: Nb stabilization prevents sensitization in 425–870°C range.
· Ash Self-Cleaning: Serrated fins reduce fouling by 50% (per EPRI study).
· Thermal Fatigue Resistance: 2x longer life than TP304H in cyclic duty.
· Customization: Fin height (12–25mm), serration depth (1–3mm), FPI (3–8).
