Ffestiniog Power Station
The Ffestiniog Power Station () is a 360 megawatts pumped-storage hydroelectricity scheme near Ffestiniog, in Gwynedd, north-west Wales. The power station at the lower reservoir has four water turbines, which can generate 360 MW of electricity within 60 seconds of the need arising. The scheme has a storage capacity of around at maximum output for four hours, and the capacity to power the whole of North Wales for several hours. The station, commissioned in 1963, was the first major pumped storage system in the UK. The upper reservoir is Llyn Stwlan with a capacity of approximately which discharges of water to the turbine generators at the power station on the bank of Llyn Ystradau (Tanygrisiau reservoir). The building of the lower reservoir flooded the route of the Ffestiniog Railway which had to build a deviation around the reservoir and power station. The plant is operated by First Hydro, a UK company owned by a joint venture of International Power and Mitsui & Co., and has ...

Gas Engine
A gas engine is an internal combustion engine that runs on a gaseous fuel, such as coal gas, producer gas, biogas, landfill gas or natural gas. In the United Kingdom, the term is unambiguous. In the United States, due to the widespread use of "gas" as an abbreviation for gasoline (petrol), such an engine might also be called a gaseous-fueled engine or natural gas engine or spark ignited. Generally in modern usage, the term ''gas engine'' refers to a heavy-duty industrial engine capable of running continuously at full load for periods approaching a high fraction of 8,760 hours per year, unlike a gasoline automobile engine, which is lightweight, high-revving and typically runs for no more than 4,000 hours in its entire life. Typical power ranges from to . History Lenoir There were many experiments with gas engines in the 19th century, but the first practical gas-fuelled internal combustion engine was built by the Belgian engineer Étienne Lenoir in 1860. However, the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lands Tribunal (England, Wales And Northern Ireland)
The Lands Tribunal was a tribunal in the United Kingdom created by the Lands Tribunal Act 1949 that had jurisdiction in England and Wales and Northern Ireland, although in the Northern Ireland context the term Lands Tribunal normally refers to a different body, the Lands Tribunal for Northern Ireland. The Lands Tribunal was unusual in having both first instance and appellate jurisdiction. The functions of the Lands Tribunal were transferred to the Upper Tribunal in June 2009 by the Transfer of Tribunal Functions (Lands Tribunal and Miscellaneous Amendments) Order 2009. Jurisdiction The Lands Tribunal was established to replace the panel of official arbitrators which had previously determined disputes as to compensation payable to the owners and occupiers of land affected by compulsory purchase. It additionally acted as the appellate tribunal hearing rating appeals from the valuation tribunals and had jurisdiction in relation to ordering the discharge or modification of restrictive ...

Royal Academy Of Arts
The Royal Academy of Arts (RA) is an art institution based in Burlington House on Piccadilly in London. Founded in 1768, it has a unique position as an independent, privately funded institution led by eminent artists and architects. Its purpose is to promote the creation, enjoyment and appreciation of the visual arts through exhibitions, education and debate. History The origin of the Royal Academy of Arts lies in an attempt in 1755 by members of the Royal Society of Arts, Society for the Encouragement of Arts, Manufactures and Commerce, principally the sculptor Henry Cheere, to found an autonomous academy of arts. Prior to this a number of artists were members of the Society for the Encouragement of Arts, Manufactures and Commerce, including Cheere and William Hogarth, or were involved in small-scale private art academies, such as the St Martin's Lane Academy. Although Cheere's attempt failed, the eventual charter, called an 'Instrument', used to establish the Royal Academy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trawsfynydd Nuclear Power Station
Trawsfynydd nuclear power station ( cy, Atomfa Trawsfynydd) is a decommissioned Magnox nuclear power station situated in Snowdonia National Park in Gwynedd, Wales. The plant, which became operational in 1965, was the only nuclear power station in the UK to be built inland, with cooling water that was taken from the man-made Llyn Trawsfynydd reservoir which also supplies the hydro-electric Maentwrog power station. It was closed in 1991. Its planned decommissioning by Magnox Ltd was expected to take almost 100years, but in 2021 the Welsh government arranged for the power station to be redeveloped using small-scale reactors. History The power station, which takes its name from the nearby village of Trawsfynydd, was designed by Basil Spence. The construction, which was undertaken by a consortium involving Crompton Parkinson, International Combustion, Fairey Engineering and Richardsons Westgarth, and known as the Atomic Power Constructions (APC), began in July 1959, and both of the ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...
