Dürnrohr Power Station

F2

The power plant Duernrohr is a steam power plant, a cogeneration plant and a thermal waste treatment plant in Zwentendorf in Lower Austria by train and boat connections.

History

The power plant was built on the site of the former hydrogenation plant Moosbierbaum and near the never went into operation in nuclear power plant Zwentendorf to use the already constructed electrical cables and switchgear in the substation Duernrohr can and close the resulting gap in the energy supply. It consists of two power plant units, of which the first has a capacity of 405 MW and the COMPOSITE Thermal Power GmbH & Co KG is one, while the second part with a capacity of 352 MW of EVN AG. It was commissioned in 1987.

The power plant has a 210 m high chimney, which is the tallest chimney and the third tallest building in Austria (see List of tallest structures in Austria ). The two units are operated with Polish and Czech coal, currently each carbon variety is used. The flue gas cleaning by electrostatic filter, a desulphurisation and denitrification plant one. The power plant can be operated with natural gas. CHP heat from the power plant supplies the towns Zwentendorf and Pischeldorf through a district heating network, which is operated by EVN heat.

In 2008, the control of the power plant in two blocks by Siemens Power Generation has been renewed. The commissioning was completed in August of the same year, since both blocks are back in full operation.

2009 is also the district heating pipeline from the power plant to St. Pölten been built by EVN heat and in operation. It is 31 km, the longest district heating pipeline in Austria and provides almost two-thirds of district heating for the state capital.

Specifications

The CO2 emissions amount to about 810 g / kWh.

Incinerator Duernrohr

In 2004 a plant for thermal waste treatment was built nearby. This is currently the largest in Austria. The conversion of this plant to 300,000 tonnes household waste saves annually about 50,000 tons of coal and 10 million cubic meters of natural gas. The rail infrastructure has been designed so that both coal and waste from the whole of Lower Austria can be brought in on the railroad. The station Moosbierbaum - Heiligeneich at the Tullnerfelder track is to envelope mass of one of the largest stations in Austria.

2010 has taken the third line of the incineration operation in the EVN waste recycling northeast, which is about the size of two existing blocks. The produced from thermal incineration steam is then for the steam turbine ECC 2, which is built in the power plant Duernrohr, converted to electricity and used for on- AGRANA bioethanol plant and to supply to the district heating pipeline to St. Polten. Similarly, a pipe conveyor was built in 2010, the coal, waste, slag and biomass can be transported to the port on the Danube Pischeldorf. Thus, it is now possible to provide for recovery alongside the train by ship waste. In Europe, this is the only system that has these logistics opportunities. For it specially Austria's largest mobile excavator was put into operation on the banks of the Danube

Pilot plant for coal replacement

On the terrain of a pilot plant for coal replacement is built. Success of the experiments is to triple its investment for productive operation be built. EVN AG plans so as to have the world's first of its kind.
