Comprehensive renewal of the Prunéřov II – OB 12 cooling towers
The work involved general repair of two Iterson-type cooling towers with a height of 120m, the diameter of the pool of cooled water being 106.6m and the design flow being 46600 t/h. The scope of repair of both towers was identical. The cooling tower shell was restored from work platforms. Holes for smokestack admissions were made into shells, reinforced by pre-stressed rings. New ascension channels and prefabricated reinforced concrete internal were performed. At the end of the general repair, stainless steel grids were mounted on the new internal to carry the new cooling fills and water supply, as were walkthrough structures also from stainless steel profiles for carrying eliminators. New winter tower protection was mounted on the upper level of the air inlet, made up of perforated FRP pipeline supplied from delivery channels. The works culminated in electro and M&R installation.
