Lippendorf Power Station
F2
The power plant lip village is a lignite -fired steam power plant on the northwest edge of the village lip village of the municipality in the district of Leipzig Neukieritzsch. It lies about 15 km south of Leipzig, which is also supplied by a district heating pipeline from the power plant with heat.
The power plant is operated by Vattenfall Europe Generation AG (formerly VEAG), which is also the owner of a block ( Block R ). The block S is one of EnBW. The power plant was inaugurated on 22 June 2000 with a speech by the then German Chancellor, Gerhard Schröder. The investment for the power plant (without mining operation) were 2.3 billion euros.
History
The first power plant construction at the site lip village, the industrial power plant Bohlen, was born 1926. This plant supplied the chemical plant Bohlen. In 1965 a new power plant next to the IKS Bohlen was built. It was used to supply the Böhlener chemical plant and the base load supply the southern GDR. This power plant consisted of a condensation power plant with four power plant units per 100 MWe power rating and of an industrial power plant, which mainly steam for chemical plant Bohlen delivered, with four busbar Turbo sets 50 megawatts.
Due to the current post-1990 environmental laws the owners decided that a retrofit with modern environmental technology for technical and economic reasons can not be realized. Therefore, the United Energy AG (VEAG ) and Bayern AG factory on the site of former industrial power plant Bohlen planned the establishment of an optimized brown coal-fired twin unit. VEAG commissioned this, the Association of VEBA power plants Ruhr AG ( VKR ) and the Energy and Environmental Technology GmbH Radebeul ( EUT ) with planning. The first version of the plan was delivered in July 1992. This was followed by studies to increase efficiency by raising the temperature of live steam and reheat steam and waste heat recovery by crude gas. These results were presented VEAG on 16 November 1992. In the planning phase for the time being a block - net efficiency of 39% was set as the target. However, this could be increased by optimizing subsequently to approximately 42.55 %. The foundation stone by the then Prime Minister of Saxony, Kurt Biedenkopf, on 29 November 1995. The first network circuit of the power plant unit S took place on June 18, 1999 at 15:42 clock. The identical block R went on 15 December of the same year in the first test run. On 22 June 2000, the plant was finally inaugurated by the then Chancellor Gerhard Schröder.
With the commissioning of the two new blocks was the gradual decommissioning and dismantling of the Altkraftwerkes lip village. The first cooling tower was demolished on December 6, 1997, the second was dismantled by means of hydraulic demolition cutter 2005. On 27 August 2005, the chimney was blown up, on 5 September 2005 was followed by the boiler house.
The first cast of the operating team was provided from within existing power plants Lippendorf and Thierenbach.
Technical Description
The power plant consists of two units, each with 933.6 MWe gross power rating. The two built by Babcock boilers, each 2420 t / h steam capacity set to its commissioning, the latest Großfeuerungstechnik for lignite in the world dar. The steam each of these boilers drives each turbo kit, an ABB turbine generator unit with 1167 MVA on. At the same time, the power plant at its disposal Inbetriebsetzungszeitpunkt about the largest and most effective lignite-fired power plant units and the most powerful Einwellenturbinen. They had a ( at the time of establishment of technically feasible highest ) Efficiency of 42.55 %. The net output of the power plant units shall each be 891 MWe. Due to the size of the systems they were designed for base load operation. Is for heating purposes by the additional output of heat a fuel efficiency of 46 percent achieved. The decoupled district heating power is a maximum of 330 MWth. You will be provided the city of Leipzig and some surrounding municipalities available. The 330 megawatt designed for a heat transfer capacity of district heating pipe to Leipzig has a length of 15 kilometers.
The time required for the power plant lignite amount of an average of 10 million tonnes per annum (2003: 11.7 million tons ) is from the open pit " United Schleenhain " MIBRAG delivered. The coal passes over an approximately 14 -kilometer-long conveyor system for the power plant - there initially to a coal blending and stack space, where it is crushed to 50 mm grain size and thus the different qualities of coal seams offset by the mixture. There can be kept in stock up to 400,000 tonnes of lignite, which the consumption of 15 days corresponds to about power plant operation. The intended service life of the mine by 40 years corresponds to the technical life of the power plant.
All legal requirements are met for air pollution control or below By modern combustion technology and extensive air purification and filtration systems. Since the used upcoming lignite has a relatively high sulfur content, flue gas desulfurization is of particular importance. This is realized by the so-called lime - additive process which provides a starting material gypsum. This serves as raw material for a next-door gypsum factory ( plasterboard ), and for a company which manufactures dental plaster. The rest of the cast is exported by rail to various European countries or stored in a opencast mine for later use. The railway logistics of the required additives and the resulting gypsum leads through the center of the German railways.
Since 2004, about 300000-320000 tonnes of sludge (about 2.5 % of the total fuel requirement ) is co-incinerated annually. By KSMV ( sewage sludge co-firing ) the sewage sludge of Braunkohlenfeuerung are metered, burned and made largely harmless by the filter systems of the power plant. With this co about 41,000 tons of lignite per year can be saved. With this addition of fuel no additional CO2 in the natural cycle is introduced, however, the Nettowirkungsrad reduced by about 0.05 % to 42.5 %. This disadvantage is however in terms of the economy (saving the lignite quantity and disposal remuneration) of sewage sludge co-firing in the background.

Others
The two 164 meter high boiler houses were up to the completion of the 172 meter high boiler houses of the power plant Niederaußem in 2002, the highest industrial building in Germany. On the Boiler House R is a viewing platform with a compass rose, which shows special placemarks in the area. The highest point of the power plant is the chimney of the auxiliary boiler plant at a height of 180 m.
On March 1, 2013 it was announced that Vattenfall intends to block R of the power plant lip village to sell. The main reason given is that Vattenfall wants to fulfill its announced in the 2010 strategic goals, set amongst the focus on increased profitability and value creation, but also to the reduction of CO2 emissions.
Environment and human health
Power plant Critics on Lippendorf the high emissions of nitrogen oxides, sulfur oxides, mercury and particulate matter, generating from the cancer substances (nickel, cadmium, PAHs, dioxins and furans) may be present. A Greenpeace at the University of Stuttgart commissioned emission study comes to the conclusion that the coal plant were attributed 212 deaths annually, on the list of " harmful to human health coal-fired power plants in Germany " ranks lip village in 3rd place Vattenfall criticized in this study that they " ... important facts and findings on the subject emissions from [ hidden ], with the clear intention to discredit the fuels such as coal and to make people afraid. " and refers to the significant drop below the legal emission limits for its power plants.
Moreover, in view of climate change are the CO2 emissions in the criticism. On published by the WWF in May 2007 List of klimaschädlichsten power plants in the EU, the Lippendorf ranked with 12.4 million tonnes of carbon dioxide in 2006 to rank 16 in Europe and ranks 8th in Germany (950 g of CO2 per kilowatt hour current), according to the power plants Niederaußem, Jaenschwalde, Frimmersdorf, Weisweiler, Neurath, Boxberg and Schwarze Pumpe.
The power plant lip village reported the following pollutant emissions in the European Register " PRTR "
Other typical pollutant emissions were not reported because they are reportable from a minimum annual amount in the PRTR only, eg Dioxins and furans from 0.0001 kg, arsenic 20 kg, 50 kg nickel, lead and zinc from 200 kg of zinc from 200 kg inorganic fluorine compounds from 5.000 kg ammonia from 10.000 kg carbon monoxide and volatile organic compounds except methane ( NMVOC) of 100,000 kg.
The European Environment Agency has estimated the cost of the environment and human health of the 28,000 largest industrial facilities in Europe based on the reported in the PRTR emissions data with the scientific methods of the European Commission. After the power plant lip village is ranked 14 of the damage costs of all European industrial plants.
