The cross flow heat exchanger for the units 1 and 2 of the Belchatów power plant station has to manage a high volumetric flow of flue gas. Therefore, Wallstein designed a solution using very high diameter tubes. The superior construction consists of 8 bundles in a row and 2 in depth. The total number of 16 bundles forms the entire cross-flow heat exchanger. As the tube material, Wallstein uses AlWaFlon®. Furthermore, we used a special tube compensator made of fluoropolymer materials for this project.
