Keadby Power Stations
Keadby Power Stations are a pair of natural gas-fired power stations near Scunthorpe in North Lincolnshire, built on the site of an older coal power station. The site lies near the B1392 and the River Trent, and the Scunthorpe-Grimsby railway. Also nearby is the Stainforth and Keadby Canal, which is part of the Sheffield and South Yorkshire Navigation. The current stations are operated by SSE Thermal. SSE also owns a 68 MWe capacity wind farm, Keadby Wind Farm, nearby. This was England's largest onshore wind farm, and started operating in July 2014. Keadby Gas Power Station Keadby Gas Power Station was commissioned on 22 January 1996, and was opened by Scottish Hydro Electric and NORWEB when the site was in South Humberside. Scottish Hydro bought the 50% share of Keadby Generation Ltd, then owned by United Utilities, in March 1997 for £253 million. It is now owned by Scottish and Southern Energy. In March 2013 the power station was 'deep mothballed' in response to advers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scottish And Southern Energy
SSE plc (formerly Scottish and Southern Energy plc) is a multinational energy company headquartered in Perth, Scotland. It is listed on the London Stock Exchange, and is a constituent of the FTSE 100 Index. SSE operates in the United Kingdom and Ireland. History Origins The company has its origins in two public sector electricity supply authorities. The former North of Scotland Hydro-Electric Board was founded in 1943 to design, construct and manage hydroelectricity projects in the Highlands of Scotland, and took over further generation and distribution responsibilities on the nationalisation of the electricity industry within the United Kingdom in 1948. The former Southern Electricity Board was created in 1948 to distribute electricity in Southern England. Whilst the Southern Electricity Board was a distribution only authority, with no power generation capacity of its own, the North of Scotland Hydro-Electric board was a broader spectrum organisation, with its own generat ...

Alternator
An alternator (or synchronous generator) 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 ...

Pulverized Coal-fired Boiler
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels. Coal is ground to the size of a fine grain, mixed with air and burned in the flue gas flow. Biomass and other materials can also be added to the mixture. Coal contains mineral matter which is converted to ash during combustion. The ash is removed as bottom ash and fly ash. The bottom ash is removed at the furnace bottom. This type of boiler dominates coal-fired power stations, providing steam to drive large turbines. History Prior to the developments leading to the use of pulverized coal, most boilers utilized grate firing where the fuel was mechanically distributed onto a moving grate at the botto ...

Base Load Power Plant
The base load (also baseload) is the minimum level of demand on an electrical grid over a span of time, for example, one week. This demand can be met by unvarying power plants or dispatchable generation, depending on which approach has the best mix of cost, availability and reliability in any particular market. The remainder of demand, varying throughout a day, is met by intermittent sources together with dispatchable generation (such as load following power plants, peaking power plants, which can be turned up or down quickly) or energy storage. Power plants that do not change their power output quickly, such as some large coal or nuclear plants, are generally called baseload power plants.Donald G. Fink, H. Wayne Beatty (ed), ''Standard Handbook for Electrical Engineers'', Eleventh Edition, Mc-Graw Hill, 1978 , pp. 12-16 through 12-18 In the 20th century most or all of base load demand was met with baseload power plants, whereas new capacity based around renewables often employs ...

Black Start
A black start is the process of restoring an electric power station, a part of an electric grid or an industrial plant, to operation without relying on the external transmission network, electric power transmission network to recover from a total or partial shutdown.Knight, U.G. ''Power Systems in Emergencies - From Contingency Planning to Crisis Management '' John Wiley & Sons 2001 section 7.5 The 'Black Start' Situation Power to restart a generating station or plant may come from an on-site black start standby generator. Alternatively, where a large amount of power is required, a tie-line to another generating plant or to an emergency generator may be used to start the facility. Once the main generating units are running, the electrical transmission network can be re-connected and electrical loads restored. Black-start power may be ensured by an agreement where a particular energy supplier is paid to make black start power available when required. Not all generating plants a ...

Steam Turbine
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work utilising a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884. It revolutionized marine propulsion and navigation to a significant extent. 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 largest steam turbine ever built is the 1,770 MW Arabelle steam turbine built by Arabelle Solutions (previously GE Steam Power), two units of which will be installed at Hinkley Point C Nuclear Power Station, England. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Recovery Steam Generator
A heat recovery steam generator (HRSG) is a 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 gas 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 flows vertically over horizontal tubes. Based on pressure levels, HRSGs can be categorized into single pressure and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
