Ince Power Station refers to two demolished power stations, which were located on a site near Ellesmere Port in Cheshire, North West England. ==Ince A== When the uranium enrichment plant at Capenhurst opened in 1949, it was realised that its power demand would require the construction of a new power station nearby. Rendel, Palmer & Tritton were appointed as the construction's civil engineering consultants, while the Central Electricity Authority engineered the station's electrical and mechanical plant. The station was built on an plot of land acquired as a result of tidal borings. The main buildings were constructed where the load-bearing sandstone was at its highest level. After the removal of of top soil it was possible to construct the buildings directly upon hard bearing sand, removing the necessity of piled foundations. However, the cooling towers and north chimney did require piled foundations as the sandstone foundation sloped away from the power station site. The station's main buildings were of a steel framed construction. The boiler house was clad using cellactite sheet cladding, and was of a semi-outdoor construction due to the speed of construction required. The turbine hall was a brick building with prefabricated stone used on window and door surrounds. The building's roof was made from asbestos cement. The floors in the station were made of quarry tile and terrazzo. The station's coal bunkers were steel plate and girder constructions. The entire building measured long by wide, containing approximately 3,800 tonnes of steel. The station also had two tall chimneys. They were made from brick and had internal diameters of . They were supported upon tall concrete plinths. The administration and amenity block was built next to the station, and connected to the turbine hall by an overhead access bridge. The block contained the station's control room, along with laboratories, administration offices, a canteen, lockers and showers. It was heated by excess steam bled from the turbines. Ince A Power Station was opened on 9 October 1957 by Lord Citrine, the chairman of the Central Electricity Authority. The station used four 60 megawatt (MW) turbo alternators, giving the station a total generation capacity of 240 MW. Each turbine was supplied with steam from a coal-fired boiler at a rate of per hour, and at a temperature of 480 °C. Each boiler and turbine set operated as an independent generating unit, with no interconnection of boilers. It was also realised mid-way through the station's construction, that the station should be capable of duel firing heavy fuel oil. Electricity was generated at 12.8 kilovolts (kV). It was then passed through a transformer which increased the voltage to 132 kV, before passing into the national grid. Coal was delivered to the station's coal storage area by rail from the East Midlands coalfields. Water for the station's systems was taken from the River Dee at Chester, and taken to the station by a pipeline built by the West Cheshire Water Board to serve the power station and the uranium enrichment plant. The water was cooled using four hyperboloid natural draft cooling towers. Each tower was tall and had a base diameter, with a cooling capacity of 2.75 million gallons per hour. 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「Ince Power Station」の詳細全文を読む スポンサード リンク
