Tříleté soužití s nadkritickým kotlem 660 MWE předsunulo společnost DITHERM (dodavatele vyzdívek) daleko dopředu

Three-year co-existence with supercritical 660 MWE boiler means DITHERM (supplier of linings) is far in advance of its time

When the Czech company, DITHERM, began the construction of the internal linings of the supercritical 660 MWe boiler at the Ledvice Power Plant (investor ČEZ) it still had no idea that it would come up with a design and subsequent materials that would be far in advance of its time. The Ledvice boiler works at a steam temperature of 600°C, while the standard temperature of the boilers is about 540°C, and steam pressure 27.3 MPa (standard is about 17 MPa). Since water is converted directly into steam at these values, there are no fluid components in it. Thus this successfully increased the efficiency of the boiler by almost 50 %. This was a big challenge for DITHERM on the demands of the aggregate’s protective lining. Thanks to expert cooperation with the boiler manufacturer, ALSTOM POWER (today GE) all the work was managed successfully.
