Grain Power Station
Grain Power Station is a CCGT power station and former oil-fired power station in Kent, England, with operational capacity of owned by Uniper (formerly E.ON UK). Oil-fired power station Grain was built on a site for the nationalised Central Electricity Generating Board. The architects were Farmer & Dark with Donald Rudd and Partners. It was built by several contractors including John Laing Construction (Civils), the Cleveland Bridge Company (steel frame and cladding), N. G. Bailey (electrical), Babcock & Wilcox (boilers) and GEC Turbine Generators Ltd (steam turbines). The site was selected in 1971 and construction had begun by 1975. The station became operational in 1979. The principal buildings were the main boiler house - turbine house block, an attached central control wing, a detached range of offices, the chimney and a gas turbine power station. The buildings are steel framed and reinforced concrete construction. The main boiler house – turbine house block was ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Grain
Isle of Grain (Old English ''Greon'', meaning gravel) is a village and the easternmost point of the Hoo Peninsula within the district of Medway in Kent, south-east England. No longer an island and now forming part of the peninsula, the area is almost all marshland and is a major habitat for diverse wetland birds. The village constitutes a civil parish, which at the 2011 census had a population of 1,648, a net decrease of 83 people in 10 years. History Extract from the ''Topographical Dictionary of Great Britain and Ireland'' by John Gorton, 1833: "GRAINE, ISLE OF, co. Kent'' "A parish in the Hundred of Hoo, lathe of Aylesford, opposite to Sheppey at the mouth of the Thames; it is about three miles and a half long, and two and a half broad and is formed by Yantlet Creek running from the Medway to the Thames. The Creek was filled up, and had a road across it for 40 years until 1823, when the Lord Mayor ordered it to be again reopened, so as to give about eight feet n ...

Storm Eunice
Storm Eunice () (known as Storm Zeynep in Germany and Storm Nora in Denmark) was an intense extratropical cyclone that was part of the 2021–2022 European windstorm season. Storm Eunice was named by the UK Met Office on 14 February 2022. A red weather warning was issued on 17 February for parts of South West England and South Wales, with a second red warning issued on 18 February, the day the storm struck, for London, the South East and East of England. Eunice set a new record for the fastest wind gust recorded in England with 122 miles per hour (196 km/h) at The Needles, Isle of Wight. The storm was one of the most powerful to impact the south coast of England since the Great Storm of 1987. The storm caused a huge amount of damage in parts of Western, Central and Northern Europe; millions of people were left without power across affected areas, and many homes had sustained damage. The UK was particularly hard hit, with 1.4 million people left without power at its peak. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen-cooled Turbogenerator
A hydrogen-cooled turbo generator is a turbo generator with gaseous hydrogen as a coolant. Hydrogen-cooled turbo generators are designed to provide a low-drag atmosphere and cooling for single-shaft and combined-cycle applications in combination with steam turbines. Because of the high thermal conductivity and other favorable properties of hydrogen gas, this is the most common type in its field today. History Based on the air-cooled turbo generator, gaseous hydrogen first went into service as the coolant in a hydrogen-cooled turbo generator in October 1937, at the Dayton Power & Light Co. in Dayton, Ohio. Design The use of gaseous hydrogen as a coolant is based on its properties, namely low density, high specific heat, and the highest thermal conductivity (at 0.168 W/(m·K)) of all gases; it is 7 to 10 times better at cooling than air. Another advantage of hydrogen is its easy detection by hydrogen sensors. A hydrogen-cooled generator can be significantly smaller, and theref ...

Heat Recovery Steam Generator
A heat recovery steam generator (''HRSG'') is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration) or used to drive a steam turbine (combined cycle). HRSGs HRSGs consist of four major components: the economizer, evaporator, superheater and water preheater . The different components are put together to meet the operating requirements of the unit. See the attached illustration of a Modular HRSG General Arrangement. Modular HRSGs can be categorized by a number of ways such as direction of exhaust gases flow or number of pressure levels. Based on the flow of exhaust gases, HRSGs are categorized into vertical and horizontal types. In horizontal type HRSGs, exhaust gas flows horizontally over vertical tubes whereas in vertical type HRSGs, exhaust gas flow vertically over horizontal tubes. Based on pressure levels, HRSGs can be categorized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquefied Natural Gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately ; maximum transport pressure is set at around ( gauge pressure), which is about one-fourth times atmospheric pressure at sea level. The gas extracted from underground hydrocarbon deposits contains a varying m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller ( turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission ( turboshaft), marine propeller or electrical generator (power turbine). Grea ...

Combined Cycle
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs. The principle is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency can be increased by 50–60%. That is, from an overall efficiency of the system of say 34% for a simple cycle, to as much as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UK Miners' Strike (1984–85)
The miners' strike of 1984–1985 was a major industrial action within the British coal industry in an attempt to prevent colliery closures. It was led by Arthur Scargill of the National Union of Mineworkers (NUM) against the National Coal Board (NCB), a government agency. Opposition to the strike was led by the Conservative government of Prime Minister Margaret Thatcher, who wanted to reduce the power of the trade unions. The NUM was divided over the action and many mineworkers, especially in the Midlands, worked through the dispute. Few major trade unions supported the NUM, primarily because of the absence of a vote at national level. Violent confrontations between flying pickets and police characterised the year-long strike, which ended in a decisive victory for the Conservative government and allowed the closure of most of Britain's collieries. Many observers regard the strike as "the most bitter industrial dispute in British history". The number of person-days of work ...

New Brighton Tower
New Brighton Tower was a steel lattice observation tower at New Brighton in the town of Wallasey, Cheshire (now in the Borough of Wirral, in Merseyside), England. It stood high, and was the tallest building in Great Britain when it opened some time between 1898 and 1900. Neglected during the First World War and requiring renovation the owners could not afford, dismantling of the tower began in 1919, and the metal was sold for scrap. The building at its base, housing the Tower Ballroom, continued in use until damaged by fire in 1969. The tower was set in large grounds, which included a boating lake, a funfair, gardens, and a sports ground. The sports ground housed, at different times, a football team, an athletics track and a motorcycle speedway track. The Beatles played at the Tower Ballroom 27 times, more than at any other venue in the United Kingdom except the Cavern Club in nearby Liverpool. Location In 1830, James Atherton purchased much of the land at Rock Point, in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Large Combustion Plant Directive
The Large Combustion Plant Directive (LCPD, 2001/80/EC) was a European Union directive which required member states of the European Union to legislatively limit flue gas emissions from combustion plant having thermal capacity of 50 MW or greater. The directive applied to fossil-fuel power stations, and other large thermal plant such as petroleum refineries and steelworks. The directive specified emission limits for sulphur dioxide, nitrogen oxides, and dust. The directive was issued in October 2001. It replaced the earlier EEC directive on large combustion plants, 88/609/EEC, issued in November 1988. Under the terms of the directive, combustion plant built after 1987 had to comply with specific emissions limits. From 2007, plant built earlier than that could either opt to comply with the emissions limits, or "opt out". Plant which opted out were limited to a maximum of 20,000 hours of further operation, and had to close completely by the end of 2015. Across Europe, 20 ...
