We have completed the chimney at ZUSOK, which is the last section in the flue gas cleaning system. Three flue pipes were placed in the shaft of the chimney – a separate one for each line (K1, K2, K3). Each pipe consists of four 20-metre segments weighing approximately 5.5 tonnes, which were lifted more than 80 m above the shaft and then lowered into the chimney where they were joined together. During the lowering process, the segments passed partially through previously installed platforms, where there is only 5 cm of clearance between the segment and the platform structure. The operation took a few days and was carried out using a crane with an arm of about 120 m.
