The coal refining company Ville / Berrenrath (formerly Briquette Factory United Ville or Briquette Factory Ville / Berrenrath ) in Hürth is one of the three remaining coal refining companies of RWE Power for " refining " ( processing ) lignite .
In the complex exclusively today is coal dust as fuel for the Kohlenstaubfeuerungen RWE own produced power plants and other industrial consumers in the region. For this purpose, the raw coal is ground and dried .
In addition to the coal processing plant, a power plant with 550 MW thermal output and an electrical output of 107 MW based on fluidized bed combustion is installed at the site, which covers the plant's own requirements and feeds electricity into the grid.
history
→ Main article lignite in Hürth
The company emerged from the Berrenrath briquette factory , sometimes referred to as the United Ville VI . This last of the six factories of the United Ville and Berrenrath opencast mines was put into operation around 1917. In 1975, the five older factories stopped production.
Although there are still 27 briquette presses at the site today , no more briquettes are produced there; the only active briquette factory in the Rheinische Revier is the former briquette factory Wachtberg , today's coal refining company Frechen .
In the past, the briquette factories were supplied directly via two inclined elevators and later conveyor belts from the connected United Ville and Berrenrath mines as well as via a narrow-gauge coal railway from the neighboring mines (Theresia, Gotteshülfe) on the eastern slope of the Ville . The briquettes were sold via the Villebahn to the state railway to Kalscheuren / Kendenich and from there via the cross railway to the port in Wesseling . Since these opencast mines have all been coaled out and closed since 1988, the company today gets its coal from the Garzweiler and Hambach large opencast mines via the siding with the north-south railway .
Equipment and performance data
The plant has a capacity of up to 5 million tons of raw coal per year; In fact, only 2.35 million tons were processed in 2007. For comparison: In the three large open-cast mines of the Rheinische Revier mentioned above, a total of almost 100 million tonnes are extracted annually.
Dust production
The raw coal is sieved, dried in 14 tube dryers to a water content of 11% and ground in ten vibrating rod mills or, since July 2012, a vertical roller mill , the construction of which required an investment of 40 million euros. From the above-mentioned 2.35 million tons of processed raw coal, about 0.8 million tons of dried dust were produced (consumption of the company's own power plant not included). The mass loss is mainly explained by the fact that the raw coal has around 60% water content; this moisture is reduced to about 11% residual moisture during drying. With the new roller system, the capacity was increased to over one million tons of dust per year, together with the Fortuna-Nord plant , over three million tons are achieved.
power plant
To cover domestic demand for energy and process heat and for economic use of waste coal preparation of the site has a power plant (since 1991) two fluidized bed - steam boilers of 550 MW thermal power. In addition to lignite, biomass ( waste wood , sewage sludge ) and secondary fuels can also be burned in the furnace .
The steam produced is converted into electricity via five steam turbines with an electrical output of 107 MW and is used to cover the power requirements of the plant. The surplus of electrical energy is fed into the grid. The grid connection is made via the Berrenrath switchgear on the 110 kV high voltage level to the power grid of the distribution network operator Rhein-Ruhr distribution network .
The waste heat is used in cogeneration to cover the heat demand of the above. Used coal dryer. Via a network with the neighboring Goldenberg power plant, the power plant also supplies various consumers in the Knapsack Chemical Park and in the other Energy and Chemical Center with process and district heating steam.
