Haverfordwest Power Station
Haverfordwest power station supplied electricity to the town of Haverfordwest, Wales and the surrounding area from 1931 to the late 1960s. It was initially owned and operated by the West Cambrian Power Company Limited, then by the British Electricity Authority following nationalisation in 1948. It comprised diesel engines driving electricity alternators. History Haverfordwest power station was commissioned in 1931 and further generating plant was added up to 1954. The power station was owned and operated by the West Cambrian Power Company Limited which also owned the power stations at Lampeter, Llandysul and St. Clears. The British electricity supply industry was nationalised in 1948, and the power company was abolished and ownership of Haverfordwest power station was vested in the British Electricity Authority. The power station was decommissioned in the late 1960s. Plant The station finally comprised eight diesel engines driving alternators. The engines were by the followin ...

British Electricity Authority
The British Electricity Authority (BEA) was established as the central British electricity authority in 1948 under the nationalisation of Great Britain's electricity supply industry enacted by the Electricity Act 1947. The BEA was responsible for the generation, transmission and sale of electricity to area electricity boards, and the development and maintenance of an efficient, coordinated and economical system of electricity supply. History The authority took over the operations of over 600 small public supply power companies, municipal authority electricity departments and the Central Electricity Board to form the BEA, which comprised a central authority and 14 area boards. Its scope did not include control of the North of Scotland Hydro-Electric Board, which had been founded in 1943 and remained independent of the BEA. The appointment of chairmen and members of the BEA and the area boards were made in August 1947 and the BEA was formally established on 15 August 1947. The ...

Central Electricity Authority
The Central Electricity Authority (CEA) was a body that managed and operated the electricity supply industry in England and Wales between 1 April 1955 and 31 December 1957. The CEA replaced the earlier British Electricity Authority (BEA) as a result of the Electricity Reorganisation (Scotland) Act 1954, which moved responsibility for Scottish electricity supply to the Scottish Office. Structure The structure of the management board and the personnel in post remained the same as the BEA with the exception of the removal of representation by the chairman of the North of Scotland Hydro-Electric Board. There was a reduction from 14 to 12 of the number of area electricity boards – the South East Scotland Electricity Board and South West Scotland Electricity Board were removed from the CEA's management. The functions of the remaining area boards were unchanged. Upon its establishment in April 1955 the chairman of the CEA was Lord Citrine; the two deputy chairmen were Sir Henry ...

Central Electricity Generating Board
The Central Electricity Generating Board (CEGB) was responsible for electricity generation, transmission and bulk sales in England and Wales from 1958 until privatisation of the electricity industry in the 1990s. It was established on 1 January 1958 to assume the functions of the Central Electricity Authority (1955–7), which had in turn replaced the British Electricity Authority (1948–55). The Electricity Council was also established in January 1958, as the coordinating and policy-making body for the British electricity supply industry. Responsibilities The CEGB was responsible for electricity generation, transmission and bulk sales in England and Wales, whilst in Scotland electricity generation was carried out by the South of Scotland Electricity Board and the North of Scotland Hydro-Electric Board. The CEGB's duty was to develop and maintain an efficient, coordinated and economical system of supply of electricity in bulk for England and Wales, and for that purpose to ...

Haverfordwest
Haverfordwest (, ; cy, Hwlffordd ) is the county town of Pembrokeshire, Wales, and the most populous urban area in Pembrokeshire with a population of 14,596 in 2011. It is also a community, being the second most populous community in the county, with 12,042 people, after Milford Haven.

Nationalisation
Nationalization (nationalisation in British English) is the process of transforming privately-owned assets into public assets by bringing them under the public ownership of a national government or state. Nationalization usually refers to private assets or to assets owned by lower levels of government (such as municipalities) being transferred to the state. Nationalization contrasts with privatization and with demutualization. When previously nationalized assets are privatized and subsequently returned to public ownership at a later stage, they are said to have undergone renationalization. Industries often subject to nationalization include the commanding heights of the economy – telecommunications, electric power, fossil fuels, railways, airlines, iron ore, media, postal services, banks, and water – though, in many jurisdictions, many such entities have no history of private ownership. Nationalization may occur with or without financial compensation to the former owners. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Demolished Power Stations In The United Kingdom
Demolition (also known as razing, cartage, and wrecking) is the science and engineering in safely and efficiently tearing down of buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes. For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through wo ...
