Hams Hall Power Station
Hams Hall Power Station refers to a series of three, now demolished coal-fired power stations, situated in Warwickshire in the West Midlands of England, northwest of Birmingham city centre. History Hams Hall A Following the death of Lord Norton in 1905, his estate was put up for sale in 1911. Part of the house was rebuilt near Cirencester, but the rest was demolished in 1920. Birmingham Corporation Electricity Supply Committee thought Hams Hall a suitable site to build a power station because of a ready supply of water in the Tame Valley, and nearness to the Warwickshire Coalfield and the Midland Railway. It was felt the Nechells power station under construction in 1919 would only have sufficient capacity to meet the needs of Birmingham for ten years. Hams Hall Power Station was constructed by the municipally owned City of Birmingham Electricity Supply Department on the site in 1928. It was opened on 6 November 1929, equipped with two Fraser & Chalmers 30,000 kW tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Electric Company Plc
The General Electric Company (GEC) was a major British industrial conglomerate involved in consumer and defence electronics, communications, and engineering. It was originally founded in 1886 as G. Binswanger and Company as an electrical goods wholesaler based in London. It quickly adopted a then-unorthodox business model of supplying electrical components over the counter. In 1889, the business was incorporated as the General Electric Company Ltd, and became a public limited company 11 years later. During the 1890s and 1900s, the company heavily invested into electric lighting, a sector that proved to be immensely profitable in the long term. The GEC was heavily impacted by the outbreak of the First World War, supplying various goods to the military, and thus becoming a major player in the electrical industry. In 1921, a new purpose-built company headquarters (Magnet House) was opened in Kingsway, London; two years later, GEC's industrial research laboratories at Wembley (late ...

Kilowatt Hour
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 33 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bar (unit)
The bar is a metric unit of pressure defined as 100,000 Pa (100 kPa), though not part of the International System of Units (SI). A pressure of 1 bar is slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes, who was a founder of the modern practice of weather forecasting, with the bar defined as one megadyne per square centimetre. The SI brochure, despite previously mentioning the bar, now omits any mention of it.. The bar has been legally recognised in countries of the European Union since 2004. British Standard BS 350:2004 ''Conversion Factors for Units''. The US National Institute of Standards and Technology (NIST) deprecates its use except for "limited use in meteorology" and lists ...

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'' or COP) 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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hansard
''Hansard'' is the transcripts of parliamentary debates in Britain and many Commonwealth of Nations, Commonwealth countries. It is named after Thomas Curson Hansard (1776–1833), a London printer and publisher, who was the first official printer to the Parliament of the United Kingdom, Parliament at Westminster. Origins Though the history of the ''Hansard'' began in the British Parliament, each of Britain's colonies developed a separate and distinctive history. Before 1771, the British Parliament had long been a highly secretive body. The official record of the actions of the House was publicly available but there was no record of the debates. The publication of remarks made in the House became a breach of parliamentary privilege, punishable by the two Houses of Parliament (UK), Houses of Parliament. As the populace became interested in parliamentary debates, more independent newspapers began publishing unofficial accounts of them. The many penalties implemented by the governmen ...

Rolls-Royce Olympus
The Rolls-Royce Olympus (originally the Bristol B.E.10 Olympus) was the world's second two- spool axial-flow turbojet aircraft engine design, first run in May 1950 and preceded only by the Pratt & Whitney J57, first-run in January 1950. It is best known as the powerplant of the Avro Vulcan and later models in the Concorde SST. The design dates to a November 1946 proposal by Bristol Aeroplane Company for a jet-powered bomber, powered by four new engines which would be supplied by Bristol Aero Engines. Although their bomber design was ultimately cancelled in favour of the other V bombers, the engine design's use of twin-spool layout led to continued interest from the Air Ministry and continued development funding. The engine first ran in 1950 and quickly outperformed its design goals. Initially used in the Vulcan, later versions added reheat for use in the supersonic BAC TSR-2. Bristol Aero Engines merged with Armstrong Siddeley Motors in 1959 to form Bristol Siddeley E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Siddeley
Bristol Siddeley Engines Ltd (BSEL) was a British aero engine manufacturer. The company was formed in 1959 by a merger of Bristol Aero-Engines Limited and Armstrong Siddeley Motors Limited. In 1961 the company was expanded by the purchase of the de Havilland Engine Company and the engine division of Blackburn Aircraft. Bristol Siddeley was purchased by Rolls-Royce Limited in 1966. History Bristol Siddeley Engines Limited was formed by the 1 April 1959 merge of Bristol Aero-Engines and Armstrong Siddeley Motors. These were the aero engine manufacturing companies of the Bristol Aeroplane Company and the Hawker Siddeley Group. The share capital of Bristol Siddeley was held in equal proportions by these two parent organisations. At around the same time Bristol's aircraft manufacturing was being subsumed into the British Aircraft Corporation along with those of English Electric and Vickers-Armstrong. Armstrong Siddeley Motors had been producing aero-engines and motor-cars sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flue Gas Stack
A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combustion, combusted in an industrial furnace, a power station, power plant's steam-generating boiler, or other large combustion device. Flue gases can also be produced from chemical or physical processes that do not involve combustion, such as Natural-gas processing, natural gas processing. Flue gas from combustion is usually composed of carbon dioxide (CO2) and water vapor, as well as nitrogen and excess oxygen remaining from the intake combustion air. It also contains a small percentage of pollutants such as Atmospheric particulate matter, particulate matter, carbon monoxide, nitrogen oxides and sulfur oxides. The flue gas stacks are often quite tall, up to , to increase the stack effect and di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooling Tower
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature. Cooling towers may either use the evaporation of water to remove heat and cool the working fluid to near the Wet-bulb temperature, wet-bulb air temperature or, in the case of ''dry cooling towers'', rely solely on air to cool the working fluid to near the Dry-bulb temperature, dry-bulb air temperature using Radiator, radiators. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are Natural convection, natural draft and Forced convection, induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
