Bold Power Station
Bold Power Station refers to a series of two coal-fired power stations in Bold near St Helens, Merseyside, North West England. They were closed, decommissioned and demolished between 1981 and 1992, and a housing estate now occupies the site. History Bold A and B Power Stations were coal fired, with a direct coal conveyor belt link from a washery at the colliery. This fed either directly to coal bunkers in both stations or to a stocking area. The extensive rail sidings were utilised for coal delivery, either from Bold Colliery or from other collieries via the main Liverpool to Manchester Lines. The coal from Bold Colliery was deep mined and therefore costly to recover. In later years, due to commercial reasons, the main coal supply became mostly by road from either Yorkshire or Scotland. The 'A' power station had an installed capacity of 120 MW. It consisted of four 30 MW two-cylinder turbines/alternators manufactured by Metropolitan-Vickers and Associated Electrical Indus ...

Pulverized Fuel Firing
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 bottom of ...

Buildings And Structures In The Metropolitan Borough Of St Helens
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the :Human habitats, human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Helens Power Station
St Helens power station supplied electricity to the Borough of St Helens and the surrounding area from 1896 to the late 1960s. The power station was developed by the St Helens Corporation which operated it up to the nationalisation of the British electricity supply industry in 1948. It was redeveloped several times to meet the increased demand for electricity. History St Helens Corporation applied in 1894 for a Provisional Order under the ''Electric Lighting Acts'' to generate and supply electricity to Borough of St Helens. An Order was granted by the Board of Trade and was confirmed by Parliament through the ''Electric Lighting Orders Confirmation (No. 1) Act 1894'' (57 & 58 Vict. c. xlix). A power station was built in Warrington Road, St Helens and was commissioned in October 1896. The Corporation charged 6d./kWh and attracted just 63 customers in its first year of operation. In 1897 the Corporation assumed control of St Helens Tramways which it intended to redevelop using el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Estate
An industrial park (also known as industrial estate, trading estate) is an area zoned and planned for the purpose of industrial development. An industrial park can be thought of as a more "heavyweight" version of a business park or office park, which has offices and light industry, rather than heavy industry. Industrial parks are notable for being relatively simple to build; they often feature speedily erected single-space steel sheds, occasionally in bright colours. Benefits Industrial parks are usually located on the edges of, or outside, the main residential area of a city, and are normally provided with good transportation access, including road and rail. One such example is the large number of industrial estates located along the River Thames in the Thames Gateway area of London. Industrial parks are usually located close to transport facilities, especially where more than one transport modes coincide, including highways, railroads, airports and ports. Another commo ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Pounds Per Square Inch
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolverhampton
Wolverhampton () is a city, metropolitan borough and administrative centre in the West Midlands, England. The population size has increased by 5.7%, from around 249,500 in 2011 to 263,700 in 2021. People from the city are called "Wulfrunians". Historically part of Staffordshire, the city grew initially as a market town specialising in the wool trade. In the Industrial Revolution, it became a major centre for coal mining, steel production, lock making, and the manufacture of cars and motorcycles. The economy of the city is still based on engineering, including a large aerospace industry, as well as the service sector. Toponym The city is named after Wulfrun, who founded the town in 985, from the Anglo-Saxon ''Wulfrūnehēantūn'' ("Wulfrūn's high or principal enclosure or farm"). Before the Norman Conquest, the area's name appears only as variants of ''Heantune'' or ''Hamtun'', the prefix ''Wulfrun'' or similar appearing in 1070 and thereafter. Alternatively, the city ma ...

Three-phase Electric Power
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used directly to power large induction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derby
Derby ( ) is a city and unitary authority area in Derbyshire, England. It lies on the banks of the River Derwent in the south of Derbyshire, which is in the East Midlands Region. It was traditionally the county town of Derbyshire. Derby gained city status in 1977, the population size has increased by 5.1%, from around 248,800 in 2011 to 261,400 in 2021. Derby was settled by Romans, who established the town of Derventio, later captured by the Anglo-Saxons, and later still by the Vikings, who made their town of one of the Five Boroughs of the Danelaw. Initially a market town, Derby grew rapidly in the industrial era. Home to Lombe's Mill, an early British factory, Derby has a claim to be one of the birthplaces of the Industrial Revolution.
