Industrial furnaces discharge high-temperature flue gas after combustion. The energy-saving air preheater recovers residual heat from waste flue gas to preheat cold combustion air sent to furnace burners.
Preheated air improves combustion completeness, cuts fuel consumption, lowers flue gas heat loss, and raises overall furnace thermal efficiency significantly.
Application:
- Metallurgy: Steel heating furnace, forging furnace, annealing furnace, aluminum melting furnace
- Petrochemical: Cracking furnace, reformer heater, crude distillation furnace
- Thermal treatment: Quenching furnace, tempering furnace, powder metallurgy furnace
- Food & Light Industry: Drying furnace, baking furnace, thermal oil furnace
- Waste treatment: Industrial waste incinerator, VOC catalytic combustion furnace
Core Energy-Saving Design Highlights
1. Counterflow heat exchange structure to maximize heat recovery efficiency
2. Fin enhanced heat transfer surface to fully recover low-grade waste heat
3. Anti-corrosion structure for cold end to avoid efficiency attenuation caused by acid corrosion
4. Supporting automatic steam/pneumatic soot blower to remove ash deposits and maintain stable energy-saving effect
5. Tight sealing design to reduce air leakage and avoid heat waste
