Little Barford Power Station
Little Barford Power Station is a combined cycle gas turbine power station in the village of Little Barford in Bedfordshire, England. It lies just south of the A428 St Neots bypass and east of the Wyboston Leisure Park. The River Great Ouse runs alongside. It was formerly the site of two coal-fired power stations, now demolished. The station is operated by RWE. The net capacity of 727 MW is sufficient to supply over half a million households. History Little Barford combined cycle gas turbine (CCGT) power station was built on the site of two former coal-fired power stations opened in 1939 and 1959 that had a generating capacity of 126 and 127 MW. Little Barford A Little Barford A station was built and operated by the Bedfordshire, Cambridgeshire and Huntingdonshire Electricity Company. It was authorised in June 1938 and commissioned in 1941. It had an installed capacity of 126MW and comprised four 31.5MW English Electric generators.''CEGB Statistical Yearbook'' (v ...

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 ...

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] |
Gas Turbine
A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous combustion, 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 electric ...

Polysulfide Bromide Battery
Polysulfides are a class of chemical compounds derived from anionic chains of sulfur atoms. There are two main classes of polysulfides: inorganic and organic. The inorganic polysulfides have the general formula . These anions are the conjugate bases of polysulfanes . Organic polysulfides generally have the formulae , where R is an alkyl or aryl group. Polysulfide salts and complexes The alkali metal polysulfides arise by treatment of a solution of the sulfide with elemental sulfur, e.g. sodium sulfide to sodium polysulfide: In some cases, these anions have been obtained as organic salts, which are soluble in organic solvents. The energy released in the reaction of sodium and elemental sulfur is the basis of battery technology. The sodium–sulfur battery and the lithium–sulfur battery require high temperatures to maintain liquid polysulfide and -conductive membranes that are unreactive toward sodium, sulfur, and sodium sulfide. Polysulfides are ligands in coordination chemi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Power
National power is defined as the sum of all resources available to a nation in the pursuit of national objectives. Assessing the national power of political entities was already a matter of relevance during the classical antiquity, the Middle Ages and the Renaissance and today. Classics Shang Yang, Guan Zhong and Chanakya, widely discussed the power of state. Many other classics, such as Mozi, Appian, Pliny the Elder,Pliny the Elder, ''Natural History'', 2:80:190, (London: Loeb, 1968). also concerned the subject. Herodotes described whence derives the power of Babylon. The considerations of Hannibal on the matter is found in Titus Livy. Elements of national power National power stems from various ''elements'', also called ''instruments'' or ''attributes''; these may be put into two groups based on their applicability and origin - "natural" and "social". * Natural: ** Geography ** Resources ** Population * Social: **Economic power, Economic **Political power, Political **Armed force ...

Swindon
Swindon () is a town in Wiltshire, England. At the time of the 2021 Census the population of the built-up area was 183,638, making it the largest settlement in the county. Located at the northeastern edge of the South West England region, Swindon lies on the M4 corridor, 84 miles (135 km) to the west of London and 36 miles (57 km) to the east of Bristol. The Cotswolds lie just to the town's north and the North Wessex Downs to its south. Recorded in the 1086 Domesday Book as ''Suindune'', the arrival of the Great Western Railway in 1843 transformed it from a small market town of 2,500 into a thriving railway hub that would become one of the largest Swindon Works, railway engineering complexes in the world at its peak. This brought with it pioneering amenities such as the UK's first lending library and a 'cradle-to-grave' healthcare centre that was later used as a blueprint for the NHS. Swindon's railway heritage can be primarily seen today with the grade 2 listed Railway Villag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
