Ferrybridge power station refers to a series of three coal-fired power stations situated on the River Aire near Ferrybridge in West Yorkshire, England. The first station on the site, Ferrybridge A power station, was constructed in the mid-1920s, and was closed in 1976; the main building has been retained as workshops. Ferrybridge B was brought into operation in the 1950s and closed in the early 1990s. In the 1960s, Ferrybridge C power station was opened with a generating capacity of 2 GW from four 500 MW sets; constructed by Central Electricity Generating Board (CEGB) in 1965; on privatisation in 1989 ownership was passed to Powergen, then to Edison Mission Energy (1999), then to AEP Energy Services (American Electric Power) (2001) and to SSE plc (2004). C power station is due to close in March 2016. Two of the four units were fitted with flue-gas desulphurisation (FGD) plant in 2009. In 2013 SSE indicated that the power station would not comply with the Industrial Emissions Directive (2010/75/EU) requiring the plant's closure by 2023 or earlier. It has since been announced that the plant will be fully closed by March 2016. Ferrybridge Multifuel 1 is a 68 MW multi-fuel plant under construction at the site which is expected to become operational during 2015. ==Ferrybridge A (1917–1976)== Land at Ferrybridge was purchased by the West Yorkshire Power Company in 1917. Plans for a power station were prepared and submitted to the Board of Trade in March 1918. Because of a system change the following year with the Electricity (Supply) Act 1919, the plans were put on hold. The plans were resubmitted to the Electricity Commissioners in January 1920. The plans were finally granted permission in November 1921, but delayed by a supply area reshuffle. A site was chosen with good access to coal, water, and good transport links including water transport.〔The Engineer, 28 October 1927, p.489, col.2〕 Construction of Ferrybridge A power station began in 1926 and the station began operating in 1927.〔 The initial station covered of the site.〔 The main buildings contained the boilers, turbines, and offices and workshops, and a smaller building housed the electrical switchgear.〔The Engineer, 28 October 1927, p.489, col.3 & Fig.3〕 Transport facilities included sidings connected to the LNER with equipment for handling wagons up to 20t, and a river wharf for transport by barge.〔 Wagon unloading was by a side tipper, into an automated weigher and then conveyors, and barge unloading was by a crane into the weighing machine.〔The Engineer, 4 November 1927, p.503, col.3, Fig. 6〕 The cooling water intakes were upstream of the wharves, initially with two filtered intakes with a minimum capacity (low water) of of water per hour.〔The Engineer, 28 October 1927, p.489, col.3; p.490, col.1〕 The power generating equipment included eight per hour water boiling capacity water tube boilers arranged in pairs, sharing air draught and chimneys ( height). The boilers were designed to produce superheated steam at at 〔The Engineer, 4 November 1927, p.504, cols. 2,3〕 The turbine/generator section had two 3000rpm three stage reaction turbines driving alternators rated at 19 MW continuous.〔The Engineer, 4 November 1927, p.504, col.3〕 The alternators produced 50 Hz 3 phase AC at 11 kV, which was stepped up to 33 kV by two sets of three single phase transformers rated at 25 MW per set.〔The Engineer, 11 November 1927, p.532, col. 1〕〔The Engineer, 4 November 1927, p.504, Fig. 8〕 The station passed into the ownership of the British Electricity Authority on the nationalisation of the UK's power industry, with the Electricity Act 1947. This company in turn became the Central Electricity Authority in 1954. The station closed on 25 October 1976, at which point it had a generating capacity of 125 MW. Ferrybridge A's boiler room and turbine hall still stand today; its single large concrete chimney has been demolished. The buildings are now used as offices and workshops,〔 by the RWE npower Technical Support Group, who are responsible for the maintenance and repairs of power station plant from around the country. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ferrybridge power stations」の詳細全文を読む スポンサード リンク
