The Mittelbüren power plant is a furnace - gas -fired power plant in Bremen . The operator is swb Generation AG & Co. KG . The furnace gas is supplied by the blast furnaces of the adjacent ArcelorMittal Bremen steelworks . The electrical output is 238 megawatts .
history
1964 - First traction current from Mittelbüren
In an energy industry cooperation between the Deutsche Bundesbahn , Stadtwerke Bremen AG and Klöcknerhütte , the Mittelbüren power plant was built in 1964 on the northern bank of the Weser on the site of the Bremen Klöcknerhütte, in the immediate vicinity of the blast furnaces. For the traction power supply planning in northwest Germany , it was necessary to build a base load power plant in the center of gravity of the route network. Bremen was chosen as the location because the blast furnace gas from two blast furnaces in the Klöcknerhütte was available as primary energy . Unit 1 went into operation in September 1964. Unit 2 was put into operation one year later. Both power plant units had an electrical output of 50 megawatts (MW) each and only supplied traction power with a frequency of 16⅔ Hertz (Hz) . The gears required for this between the turbines and the traction current generators and the two generators themselves were new developments that were first used on this scale in the new base load power plants for generating traction current. To compensate for the fluctuating supply of blast furnace gas, heavy fuel oil was used as additional primary energy in both power plant blocks. Both Unit 1 and Unit 2 have now been shut down and the boiler houses dismantled.
Note on the name: Mittelbüren was a district of the former village of Büren , but it was on the left bank of the Weser.
1974 - Unit 3 and GT3 put into operation
In January 1974 Unit 3 was put into service. The unit, which was primarily fired with furnace gas, generated 16⅔ Hz traction current with an electrical output of 110 MW. Natural gas was used as a substitute fuel to compensate for the fluctuating supply of top gas .
In October 1974 the GT3 gas turbine system went into operation , which, with a start-up time of just 2.5 minutes and an output of 88 MW, is used electrically to generate minute reserve and peak load and, in an emergency, to restore the power supply to Bremen. The generator is driven by three single-casing, single-stage gas turbines which are coupled in series with the generator. Six Rolls-Royce-Avon jet engines operated with extra light heating oil serve as propellant gas generators for the gas turbines .
1975 - Unit 4 started up
In contrast to Units 1 to 3 of the Mittelbüren power station, Unit 4, which went into operation in 1975, generates 50 Hertz electricity. The Benson boiler, Block 4, was originally fired with natural gas and heavy oil. In 2002 the furnace was switched to furnace gas and natural gas as a substitute fuel when there was insufficient furnace gas supply. The electrical output is 150 MW with furnace gas operation and 60 MW with pure natural gas operation. Block 4 has a chimney with a height of 197 meters .
1996 - Construction of the fully static frequency coupling in Bremen
The fully static frequency converter with an output of 100 MW installed on the western border of the Mittelbüren power station in 1996 makes it possible to convert 50 Hz electricity from other power plants into 16.7 Hz traction current when there is an increased demand for traction power, as well as when there is a low demand for traction power (e.g. B. at night and on weekends) to use the generated traction current in the 50 Hz network. Until the three railway power blocks were shut down, the second aspect played the more important role because it enabled the continuously accumulating top gas to be used in full regardless of the rail power requirement.
2002/2004 - Units 1 and 2 were shut down
Unit 1 was decommissioned on April 1, 2002. Unit 2 was decommissioned on January 1, 2004. In 2008, the boiler houses of the two units were completely dismantled.
2011 - Co-incineration of converter gas
Since April 2011, converter gas has been added to the furnace gas used to generate electricity in Units 3 and 4 , which is produced during crude steel production using the Linz-Donawitz process (LD process) at the ArcelorMittal Bremen plant.
2013 - Block 3 closed
Block 3 was shut down in March 2013.
Mains connection
Unit 4 and gas turbine 3 are connected to the grid at the 110 kV high-voltage level in the power grid of the distribution network operator Wesernetz Bremen GmbH .
The Weser overhead line crossing Bremen-Industriehafen is located near the power plant .
