Harrogate Power Station
Harrogate power station supplied electricity to the town of Harrogate and the surrounding area from 1897 to 1960. The power station was built by the Harrogate Corporation which operated it until the nationalisation of the British electricity supply industry in 1948. History The Harrogate Corporation applied for a Provisional Order under the ''Electric Lighting Acts'' to generate and supply electricity to the town of Harrogate. An Order was granted by the Board of Trade and was confirmed by Parliament through the ''Electric Lighting Orders Confirmation (No. 1) Act 1891'' (54 & 55 Vict. c. xlix). The power station was built north of the town off Ripon Road Harrogate (54°00’03”N 01°33’17”W); it began to supply electricity on 14 April 1897. The site was adjacent to the Oak Beck which provided make-up water to the station's spray cooling pond. The Central Electricity Board built the first stages of the National Grid between 1927 and 1933. Harrogate power station w ...

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. Th ...

Coal-fired Power Stations In England
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 woo ...

Thermal Efficiency
In thermodynamics, the thermal efficiency (\eta_) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the ''coefficient of performance'') is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is fractional as the output is always less than the input while the COP of a heat pump is more than 1. These values are further restricted by the Carnot theorem. Overview In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, Q_, to the device is heat, or the heat-content of a fuel that is consumed. The de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pound Per Square Inch
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the ... [...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 ...

Nationalization
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 He ...
