The Frankfurt Railway Power Plant was a coal-fired power plant operated as a thermal power plant in Frankfurt (Main) , located on Gutleutstrasse, from 1966 to 1995 .

history

It supplied the traction current network in the Frankfurt area and, via a district heating network , all of the major heat consumers of the Deutsche Bundesbahn in the area of Frankfurt Central Station . It replaced the "Fernheizwerk 2" standing in the same place, as well as the former "Fernheizwerk 1" in Mannheimer Strasse.

In 2014, the power plants were demolished to enable the construction of residential complexes.

Former "District Heating Plant 2"

With the construction of the Frankfurt main train station in 1888, two years later in 1890 a pump plant was put into operation to supply the steam locomotives with boiler feed water in the main station area. The water from the Main was pumped into an 800 m³ water tower via 6 steam-operated piston pumps, the " Main water pumping station", from where it was available to the supply network for the feed water supply. Up until 1920, the pressurized water network, which was used to operate the hydraulic elevators at Frankfurt Central Station, was fed by an additional pump .

In 1915 work began on expanding the pumping station into a power station. For this purpose, the three hand-fired flame tube boilers were exchanged for three Garbe water tube boilers (13.5 atmospheres, 10 t / h, overheating 350 ° C), as well as two steam turbines , each with 1750 kW, 50 Hz three-phase current (6.6 kV), as A large filter system (gravel filter) for cleaning the feed water is also installed. The pumps were also converted to electric drive. The task of the new power plant was initially to supply power to the newly built repair shop in Frankfurt-Nied. Due to the fact that electricity in the repair shop was only purchased on weekdays and the associated shutdown of the power plant every weekend, it was very uneconomical. Since the turbines and boiler fittings had to be surrendered in the course of reparations payments in 1924, the power supply for the repair shop was switched to the Höchst power plants on the Main. In 1926, with the help of the existing boilers, the still operated pumping system was expanded to "Fernheizwerk 2", which supported "Fernheizwerk 1" in heating operation and thus made the operation of heating locomotives in the Frankfurt outer station superfluous from 1927 . In 1956 and 1960 the Garbe boilers were exchanged for the Borsig radiant boilers, later designated as boilers 1 and 2, so that the "district heating plant 1" could be taken out of operation. The "Fernheizwerk 2" thus supplied the entire main station area with all buildings, the train preheating systems, the railway depots 1–3, the office buildings, the overnight buildings and the gas station until it was converted into the "Heizkraftwerk Frankfurt am Main" .

Conversion to the "Frankfurt am Main combined heat and power plant"

In the course of the increasing need for heating steam to around 80 t / h in winter (Posthalle as an additional consumer), as well as the advancing electrification of the railway lines in the Frankfurt area, the necessary prerequisites arose for the Deutsche Bundesbahn to provide a central energy supply for the greater Frankfurt area in the form of a thermal power station ( Thermal power coupling ). As a result, the planning of a heating and power plant on the area of ​​"Fernheizwerk 2" began in 1962. The following requirements were placed on the thermal power station:

During the winter months:

• Supply of the major hub Frankfurt (Main) with turbine exhaust steam (7 atü) for heating purposes (at least 132 t / h)
• Generation of traction current up to 12 MW at 16 2/3 Hz in connection mode.

During the summer months:

• Generation of live steam for heating purposes (at least 25 t / h)
• Generation of reactive current with the traction current generator (phase shifter operation)

In the same year, the design was approved and the renovation began. The last Garbe boiler was removed and replaced by two new Borsig radiation boilers (boilers 3 and 4). Since the functionality of the heating system had to be guaranteed in the respective heating periods, the old boiler house was demolished in several sections, so that always two boilers (1962/1963: boiler 1 and 2, 1963/1964: boiler 4, 1964/1965: boiler 3 and 4) were available for steam generation. The boilers were already put into operation, although parts of the new boiler house were not yet finished. In 1963/1964, for example, fan heaters had to be installed in the boiler house to prevent the boiler fittings from freezing, as one of the side walls was not yet glazed and covered with boards. In the summer months, however, the district heating plant was completely shut down. In December 1966, the thermal power station was fully commissioned and electricity was supplied to the traction network. The following were supplied with heating steam:

• the main passenger station Frankfurt (Main)
• the main freight station Frankfurt (Main)
• the headquarters of the Deutsche Bundesbahn
• the administrative building Federal Railway Directorate Frankfurt (Main)
• the post hall
• the depot 1–3
• the railway vehicle works
• the repair shop Frankfurt (Main)
• the railway maintenance office
• the central signal box "Ff", as well as the signal box "Fzf" and "Fa"

In 1986 a flue gas desulphurisation system was retrofitted and the firing switched from coal to oil.

As a result of the privatization in 1994, the heat and power plant became increasingly unprofitable in terms of size and independence, especially since the West heat and power plant in the immediate vicinity came into question as a steam and electricity supplier. In 1995 the thermal power station was shut down and demolished in 2014 to develop living space.
