Power Plant in Kozienice, Poland

Cost reduction and highest standards of quality and safety
The Kozienice power plant, working since 1972, is the second largest coal power station of Poland and the first one with regard to productive capacity.

Description

The Kozienice power plant, working since 1972, is the second largest coal power station of Poland and the first one with regard to productive capacity. A new energy unit is under construction since 2012. With 1,075 MW, it will increase national energy production by nearly 5%.

ULMA Solution

ULMA supplied equipment for the construction of several installations of the project: the boiler house, the flue-gas desulphurisation system, the building for electric equipment and the cooling tower.

  • Boiler house

For the 87.1 x 63.35 m big and between 3 and 6 m high boiler house, 20,000 m3 of concrete were poured in a single stage. The solid walls necessary in the foundations were built with single-sided SMK trusses assembled with MK walers which made them compatible with any type of wall formwork, in this case ORMA Modular Formwork. This phase also included 3.3 m high canalisations built with the same system of single-sided wall formwork.

    • Flue-gas desulphurisation system

The geometry of each structure determined the choice of product:

    • ORMA for the straight walls due to its high efficiency and minimum labour and assembly costs
    • BIRA for the curved walls since its simple curving mechanism easily adapts to the required curvature
    • ENKOFLEX for the slabs, powerful in irregular geometries
  • Cooling tower

At 13 m height, the construction of the circular beam made up of prefabricated beams required a working space to join the different segments. The 2.25 x 2.65 m working platforms with the MK system eased and ensured the pouring in between the beams.

The project includes a 4 m wide and 2.7 m high underground hot water pipe running from the tower perimeter towards the center where it reaches 20 m height. The walls were built with ORMA while for the roof perimeter Tables VR of two sizes were used: 150 x 270 cm and 150 x 360 cm easy-to-handle and adaptable to any area.

ULMA accomplished the challenging requirements of this type of projects: cost reduction and highest standards of quality and safety.
