New Filter Plant in Medupi, South Africa

The South African energy company Eskom has built one of the world's largest coal-fired power plants in Medupi with a capacity of about 4,800 MW, about 400 km (248.5 mi) north of Johannesburg.

It consists of six 800 MW blocks. The power plant will be equipped with the latest bag filter systems for dust reduction.

Design in RFEM

Dlubal's long-time customer Prof. Schmidt & Partner was commissioned by the company Balcke-Dürr, NL Rothemühle, with the structural design and calculation of the bag filter housing, including the flue gas/clean gas ducts, the support structure, and the staircase housing. The supporting structure with the total dimensions of W/L/H = 18 m / 48 m / 27 m (59 ft / 157.4 ft / 88.5 ft) was entered in RFEM because it turned out to be useful in determining the structure in an FE model. The consideration of South African standards and semi-finished products (sections) posed a particular challenge. The extensive RFEM cross-section library was a great help here. The supporting structure was designed structurally and dynamically, including for various temperature conditions and the seismic load case.
