Deeside Power Station
Deeside Power Station is a power station on the Deeside Industrial Park to the north of Connah's Quay in Flintshire, Wales. Constructed as a 498 MWe combined-cycle gas plant, it is now used to provide inertial response and reactive power services to the grid. It is a mile from the 1,420 MW Connah's Quay Power Station, owned by Uniper. The power stations are separated by the Flintshire Bridge. History Deeside power station is sited on land of a former British Steel Corporation steelworks, and was commissioned in November 1994, costing £200 million. Built by Alstom for National Power, it is now owned by Triton Power. In April 2002, 250 MW of capacity at the plant was mothballed when the price of electricity dropped. The station resumed full power in October 2003. In March 2018, the plant was again mothballed, and in January 2020 it was awarded a contract to supply the National Grid with inertial response and reactive power services. Work to repurpose the ...

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 ...

Ratingen
Ratingen (; ) is a town in the district of Mettmann in North Rhine-Westphalia, Germany. It lies in the northwestern part of Berg about 12 km northeast of Düsseldorf. Administration With a communal reform of 1975 the independent municipalities of Breitscheid, Eggerscheidt, Hösel, Lintorf (seat Angerland) as well as the local part of Homberg and the municipality of Homberg-Meiersberg (seat Hubbelrath) were added to the city of Ratingen. History Ratingen was settled before 849. From the Middle Ages the Ratingen area belonged to the count and later dukes of Berg. On December 11, 1276 the settlement received city rights. Ratingen was one of the four places of Berg which experienced an economic boom in the end of the Middle Ages, but slowed during the Thirty Years' War. At the beginning of the Industrial Age, the first manufacturing plants opened in 1783. In Cromford the first mechanical spinnery of Europe opened, which grew into the '' Textilfabrik Cromford'', now part ... [...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] |
River Dee, Wales
The River Dee (, ) flows through North Wales and Cheshire, England. The majority of the river is located in Wales, with the stretch between Aldford and Saltney within England and two other sections forming the border between the two countries. The length of the section from Bala to Chester is . The river rises on Dduallt in Snowdonia and flows east through Bala Lake, Corwen, and Llangollen. It turns north near Overton-on-Dee and forms part of the England–Wales border before fully entering England near Aldford, north-east of Wrexham. It flows through Chester then re-enters Wales near Saltney; the final section is canalised and discharges to the Irish Sea via an estuary long. History The River Dee was the traditional boundary of the Kingdom of Gwynedd in Wales for centuries, possibly since its founding in the 5th century. It was recorded in the 13th century (in mainstream Middle English orthography, lacking the letters v and w) as ''flumen Dubr Duiu''; the name appe ...

Surface Condenser
A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These Condenser (heat transfer), condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure. Where cooling water is in short supply, an air-cooled condenser is often used. An air-cooled condenser is however, significantly more expensive and cannot achieve as low a steam turbine exhaust pressure (and temperature) as a water-cooled surface condenser. Surface condensers are also used in applications and industries other than the condensing of steam turbine exhaust in power plants. Purpose In thermal power plants, the purpose of a surface condenser is to condensation, condense the exhaust steam from a steam turbine to obtain maximum Thermal efficiency, efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so tha ...

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] |
Transformer
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple Electrical network, circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force, electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change Alternating current, AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
