Flue gas treatment in waste incineration presents unique technical challenges, especially when waste heat recovery is required. Flue gases often contain corrosive compounds such as SO₂, SO₃, NOₓ, hydrofluoric acid (HF), and hydrochloric acid (HCl), which can quickly damage conventional metal heat exchangers.
CALORPLAST tube bundle heat exchangers are made entirely from corrosion-resistant plastics, making them the ideal solution for these demanding environments. They are widely used for waste heat recovery in waste and sewage sludge incineration, particularly where flue gases have already been partially cooled.
The all-plastic construction ensures long service life, reliable performance, and minimal maintenance—even in highly corrosive applications.
