The Dürnrohr power plant is a steam power plant , a CHP plant and a thermal waste treatment plant in Zwentendorf in Lower Austria with rail and ship connections. After almost 33 years, electricity generation with coal was discontinued at the beginning of August 2019.
history
The power plant was built on the site of the former Moosbierbaum hydrogenation plant and near the Zwentendorf nuclear power plant , which never went into operation , in order to be able to use the electrical lines and switchgear that had already been built in the Dürnrohr transformer station and to close the gap in the energy supply. It consists of two power plant blocks, the first of which has an output of 405 MW and belongs to VERBUND Thermal Power GmbH & Co KG , while the second with an output of 352 MW belongs to EVN AG . It was put into operation in 1987.
The power plant has a 210 m high chimney, which is the tallest chimney and the third tallest structure in Austria (see list of tallest structures in Austria ). The two units were operated with Polish and Czech hard coal , although the Republic of Austria had already been working on coal supply contracts with the Węglokoks company in Poland , which was economically difficult at the time, as well as related guarantee liabilities since 1974 . The flue gas was cleaned by an electrostatic precipitator , a desulphurisation system and a denitrification system. The power plant can also be operated with natural gas . CHP heat from the power plant supplies the towns of Zwentendorf and Pischelsdorf through a district heating network operated by EVN Wärme .
In 2008, the control technology of the power plant in both units was renewed by Siemens Power Generation . Commissioning was completed in August of the same year, and both units have been fully operational again since then.
In 2009, the district heating pipeline from the power plant to St. Pölten was installed and is in operation by EVN Wärme . At 31 km, it is the longest district heating pipe in Austria and provides almost two thirds of the district heating for the state capital.
In May 2014, Verbund AG announced the closure of its part of the Dürnrohr hard coal-fired power plant for economic reasons. The first power plant block was closed on April 30, 2015. The coal combustion in the only remaining block 2 (EVN block) was stopped on August 2, 2019. In addition to generating energy through waste incineration, sewage sludge is to be recycled and a large photovoltaic system is to be built at the site.
Technical specifications
The CO 2 emissions in 2011 were approx. 810 g / kWh .
Bomb find
During World War II , the industrial area around the places Moosbierbaum and Dürnrohr was the target of bombs . A bomb was uncovered when the ground was leveled at the former power station. The demining service defused them by unscrewing 2 intact detonators.
Photovoltaic power plant (under construction)
Preparatory work for "one of the largest photovoltaic systems in Austria" is ongoing at the site of the former coal-fired power plant.
Dürnrohr waste incineration plant
In 2004, a facility for thermal waste treatment was built in the immediate vicinity . This is currently the largest in Austria. The conversion of this plant to 300,000 t of household waste saves around 50,000 t of coal and 10 million m³ of natural gas annually. The rail infrastructure was designed in such a way that both coal and waste from all over Lower Austria can be transported by rail. The Moosbierbaum-Heiligeneich station on the Tullnerfelder Bahn is one of the largest train stations in Austria in terms of handling volume.
In 2010 EVN Waste Utilization Lower Austria put the third waste incineration line into operation, which is about the size of the two existing blocks. The steam generated during thermal waste incineration is then converted into electricity via the EVZ 2 steam turbine in the Dürnrohr power plant and used for the Agrana bioethanol plant and for feeding into the district heating pipeline to St. Pölten. A tubular belt conveyor was also installed in 2010 that can transport coal, garbage, slag and biomass to the Pischelsdorf Danube port . This now makes it possible to deliver garbage for recycling by ship as well as by rail. This is the only facility in Europe that has these logistics options. Austria's largest mobile material handler was put into operation on the Donaulände for this purpose.
