The Mělník power plant (in Czech Elektrárna Mělník , abbreviation EME ) is a lignite power plant near Horní Počaply on the Elbe, about 10 km northwest of Mělník , Středočeský kraj, Czech Republic.
The operator of Mělník I is Energotrans , the operator of Mělník II and III is ČEZ . The Mělník power plant is the closest coal-fired power plant to the capital of Prague . It lies about 13 kilometers below the confluence of the Elbe and Vltava rivers .
history
The power plant used to consist of three units (EME I, EME II and EME III), which were built in several phases between the late 1960s and the early 1980s, when power plants were built to extract lignite from the mines in North and West Bohemia were burned. In October 1993 EME I was separated from ČEZ and was operated by the Melnik-Praha joint stock company , which is now called Energotrans, as.
Mělník I power plant
Energotrans invested 1.45 billion Czech crowns in the desulphurisation of the Mělník I power plant. The additional costs for the project were 300 million Czech crowns. The supplier for the project was Asea Brown Boveri . Over 70% of the project was carried out by Czech companies from the ABB group and their domestic subcontractors. The gypsum as a by-product of electricity generation is accepted by building material manufacturers. Mělník I has an electrical output of 6 × 55 MW and a thermal output of 6 × 163 MW. Mělník I started operating in 1961 and will remain in operation for at least 20 years after the modernization.
Mělník II power plant
The first four units of the Mělník II power plant, the chimney of which is 270 meters high, went into operation in November 1971. In the period from 1971 to 1976, the most important devices were gradually optimized. In the following years, the system technology was modernized.
A resolution was passed that only two units should continue to operate in order to comply with the new Environmental Protection Act of January 1, 1999. Between 1994 and 1996, the two units that were in operation were completely reconstructed. New systems were installed in order to be able to extract heat in the future. A new Westinghouse WPDF II I&C system was also installed. The boilers have been reconstructed to reduce NO x emissions. Desulphurization plants were put into operation in the second half of 1998. The other two units, which were not reconstructed, were shut down on December 31, 1998. District heating from Mělník II has been fed into the local district heating network since 2000. This supplies the town of Mělník, the village of Horní Počáply and Dolní Beřkovice . The output of the Mělník II power plant is 110 MW per unit.
Mělník III power plant
The Mělník III power plant with an output of 500 MW started operations in 1981. This block is the largest coal-fired block in the Czech Republic. With the block, a new composition of control technology was put into operation for the first time. Its advanced technology made the block one of the most economical coal blocks. In the course of time, major modernizations and renovations were carried out. In 1981 and 1982 a series of measurements and tests were carried out. At the beginning of the operation of Mělník III, solutions had to be found for the fundamental problems in the area of cost management. As with Mělník II, solutions had to be found to burn low quality coal. Despite these efforts, the plant only achieved a maximum output of 470 MW. The investments from 1994 to 1998 focused on extending the service life by at least another 20 years. A high-pressure part of the turbine was reconstructed so that the system achieved the original output of 500 MW. As part of the general overhaul, primary measures to reduce NO x emissions were taken. At the end of 1998, desulphurisation plants with an efficiency of 95% were put into operation, similar to Mělník II. The plaster of paris from the power station is processed into plasterboard as a by-product of electricity generation in a nearby plasterboard plant . Fly ash and slag are also used in the construction industry. In 2002 the power plant received a certificate for the Environmental Management System .
District heating
In addition to generating electrical energy, the Mělník power plant also provides district heating. Electricity and district heating are produced in a common, combined cycle. This leads to better fuel efficiency and thus to energy savings. District heating is supplied through a pipeline to the town of Mělník, the municipality of Horní Počaply, to other consumers in the region and in the vicinity of the power station, as well as a 32-kilometer route to the Prague- Třeboradice heating station 50 ° 9 ′ 52.8 ″ N , 14 ° 30 ′ 54.1 ″ E headed. The turbines could have a total thermal output of 340 MW, of which only 80 MW are used.
