The regenerative burner system recovers heat from high-temperature flue gas and uses it to preheat combustion air. This improves fuel utilization and helps reduce the cost per ton of molten aluminum.
For scrap and recycled aluminum, twin-chamber and side-well furnace designs can use a molten aluminum pump to create a vortex. Scrap is fed into the vortex for immersive melting, helping reduce oxidation and metal loss.
A twin-chamber furnace can be designed with a secondary chamber door bridge. Large unbroken scrap can be preheated, de-painted and melted through internal flue gas circulation while the secondary chamber maintains a lower oxygen atmosphere.
Low-temperature and high-temperature gas intake channels, wide-angle burner nozzles, flue gas recirculation and precise air-gas ratio control reduce local high-temperature flame concentration and help lower NOx emissions.
The furnace shell uses qualified steel plates and section steel. Scientific structural design supports the strength requirements of different capacities and furnace types, with a service life of over 10 years under proper use.
Segmented furnace doors reduce deformation caused by thermal cycling. Precision-machined heat-resistant castings around the furnace entrance improve sealing, and externally bolted castings are easier to replace.
