At Home in Lignite …
It is not only coal power plants but also lignite-fired ones which can guarantee an
assured supply of electricity around the clock. Over the past few years various energy
suppliers have either started to modernize their lignite power plants or to rebuild them.
On account of its many years of experience with this fuel, Hitachi Power Europe has
established itself as a supplier of the latest generation of highly efficient utility steam
generators for these projects.
For example: the two new RWE Power AG power plant units (total 2,240 megawatts
capacity) at the Neurath site. This is where Hitachi Power Europe, as consortium leader,
is erecting two utility steam generators with an efficiency up to 43 % – a peak figure
worldwide. The two units represent the latest stage reached in steam generator
technology across the world. They feature supercritical steam pressures and the highest
steam temperatures ever realized for lignite.
Hitachi Power Europe has also erected an ultra-modern utility steam generator for a new
lignite power plant unit at Boxberg in Saxony and placed it into operation. Just like other
customers, Vattenfall relies on the large lignite reserves which make it possible for lignite
power plants to be built and operated. Thanks to the much greater degrees of efficiency,
the new plants emit much less CO 2 than today’s power plants. At the same time, the
plants conserve valuable resources since less fuel is needed for the same quantity of
electricity.
A further benefit is that Hitachi Power Europe has its own firing technology components
which are optimally adapted to the particular requirements of the various lignite types
(e. g. circular jet burners).
