The Krauss-Maffei gypsum centrifuge VZU-G is most suitable for desulfurization of flue gases from coal-fired heat/ power plants, waste incinerators, and copper smelters. Washing the flue gas with limestone slurry is the most successful method and generates reusable gypsum.
The development of many different processes for desulfurization of flue gases from coal-fired heat and power plants started more than four decades ago.
Washing the flue gas with a limestone slurry became established as the most successful method. Efficient dewatering provides gypsum slurry as an end product with good reusability. High purity levels and low residual moisture are best obtained using Krauss-Maffei vertical centrifuges. ANDRITZ KMPT has extensive experience in gypsum dewatering, as well as in corrosion and wear protection as it has over 400 machines operating successfully worldwide. Continuous improvements to our machines guarantee reliability and maximum efficiency.
