Product Description
The 321 stainless steel high-temperature centrifugal exhaust fan is a top-tier power equipment designed specifically for harsh, high-temperature industrial environments. It is manufactured using internationally standardized AISI 321 stainless steel (titanium-stabilized austenitic stainless steel). Its core characteristics lie in its superior high-temperature resistance, oxidation resistance, and resistance to intergranular corrosion, enabling stable and efficient continuous handling of extreme high-temperature flue gas media up to 900°C.
Core Advantages
1. Extreme High-Temperature Resistance: Can withstand media temperatures up to 900°C with stable performance.
2. Superior Corrosion Resistance: The 321 material effectively resists acid dew point corrosion and intergranular corrosion in flue gas.
3. Long-Lasting Creep Resistance: High mechanical strength at high temperatures, resulting in a service life far exceeding that of ordinary materials.
4. High-Efficiency Energy-Saving Design: Aerodynamically optimized impeller provides large air volume and high negative pressure.
5. Fully Customized Service: One-to-one design based on operating parameters (temperature, flow rate, pressure, media).
6. The casing, impeller, main shaft, and air inlet—all core components—are made of high-quality 321 stainless steel plates/castings. Key areas are reinforced to ensure structural integrity and prevent deformation at high temperatures.
7. Standard configuration includes a water-cooling jacket or forced air cooling to ensure bearings operate at safe temperatures.
8. Shaft sealing system: Employs various methods such as labyrinth seals, gas seals, or packing seals to prevent heat and media leakage, ensuring safety.
Applications
Heat Treatment Industry: Flue gas emissions from annealing furnaces, quenching furnaces, tempering furnaces, and carburizing furnaces.
Environmental Protection and Energy Industry: Induced draft systems for waste incinerators, hazardous waste incinerators, biomass boilers, and coal-fired boilers.
Chemical and Metallurgical Industry: High-temperature gas transport from chemical cracking furnaces, coke ovens, steelmaking furnaces, and ceramic kilns.
Drying Industry: Hot air circulation and exhaust in high-temperature drying equipment and spray drying towers.
