Heilbronn Power Station
The power plant Heilbronn is a coal-fired power plant in Heilbronn.
It is operated by the Energie Baden-Württemberg and has seven power units. The electrical performance of the three blocks in operation is 940 MW, two units with a capacity of approximately 200 MW were put into cold reserve in 1997.
The facility is located in Heilbronn's industrial estate at the northern end of the canal harbor. About the River Neckar, the cooling water required is taken, at the same time the delivery of the coal takes place by barge on the river or by rail over the port rail.
A separately standing busbar power plant from the 1920s, which was decommissioned in the 1950s, is used since 1998 as an event center (Block E).
The CO2 emissions of the power plant was, according to the WWF in 2006, 4.4 million tons / year, or 950 g / kWh. The power plant Heilbronn making it one of the 30 coal-fired power plants with the largest absolute CO2 emissions in Germany.
Blocks 1-6
Blocks 1 to 4, with a capacity of 2 × 55 MW and 2 × 100 MW were built in the 1950s and 1960s, with the first two blocks were shut down in 1988 and Units 3 and 4, 2006. The built 1964-1966 Units 5 and 6 remain, each with 130 MW.
By 1986, the existing power plant had three chimneys each with 140 meters mouth height (each a chimney for blocks 4, 5 and 6) and two chimneys with 70 meters mouth height (one chimney for Unit 3 and a common chimney for Units 1 and 2 ). Originally three chimneys with a muzzle height of 70 meters were available, one was later replaced by a stack of 140 m height mouth. The last remaining chimney of Units 1 and 2 was canceled in early 2009.
End of February 2014 it was announced that EnBW has decided the closure of the still in operation Altblöcke 5 and 6.
Block 7
In the years 1982-1986 the block 7 was built with a capacity of 750 MW as a means of load power plant, for it was a new, 140 m high cooling tower and a 250 m high chimney. The block have from the outset of a flue gas desulfurization and denitrification -. Due to the amendment of the Large Combustion Plant Regulation in 1983, both had to be retrofitted for units 3 to 6, so that a further operation was possible. In addition, in 1986 a second chimney in the same design and height was built at block 7 for the four blocks. The two chimneys are widely recognized as a landmark. Together with the two chimneys of the power station Altbach / Deizisau they are the tallest freestanding structures in Baden-Württemberg.
About a combined heat and power generation industries in Heilbronn and Neckarsulm by the power plant are additionally supplied with district heating. Since 1998, the facility has a permit for the co-incineration of sewage sludge, since 2003, petroleum coke may also be burned.
Cooling Tower
In the plate of the 140 meter high natural draft cooling tower of unit 7, the water is highly 180 centimeters. This cooling tower plate has a circumference of 330 meters and a diameter of 104.7 meters. The dissolved water in the Neckar sludge shall be 50 inches high on top of the water- plate of concrete. The stairs outside the cooling tower has 67 levels and leads to 15 meters in height. The orifice diameter of the tower was 78 meters. Approximately 16 cubic meters of water per second, which comes out of the nozzles in the cooling tower drops, droplet shaped by the fill- down. On the other hand, air flows and cools the water. 250 liters of water are taken from the Neckar per second, approved would be 650 liters. The slats that spray out the water located on 15 meters. Per second evaporate as 0.33 cubic meters of water.
Mains connection
The mains connection of units 5 and 6 via the switchgear Heilbronn on the 110- kV high-voltage level in the mains distribution providers EnBW Regional. The mains connection of the block 7 via the switchgear Großgartach on the 380 kV high- voltage level in the power grid of the transmission system operator Transnet BW.
Further plans
In September 2006, wanting to expand their conventional power plant, EnBW announced. In conversation the locations Karlsruhe and Heilbronn were. Meanwhile, EnBW has decided to Karlsruhe and Heilbronn against, as the reason the difficult supply of the plant was called for with gas power plant.
