Poolbeg Generating Station
Poolbeg Generating Station ( ga, Cumhachtstáisiún an Phoill Bhig), colloquially known as The Poolbeg Stacks, is a power station owned and operated by the Electricity Supply Board of Ireland (ESB). There are two stations on the site, the older thermal station containing units 1, 2, and 3 and the combined cycle gas station containing units CG14, CG15 and ST16, which is located toward the eastern end of the site. The six units have a total installed capacity of 1020 MW. The plant is located on the Poolbeg peninsula, an artificial peninsula built of reclaimed land to the east of Ringsend, Dublin, on the south bank of Dublin Port. Its two chimneys, at just over 207 metres, are visible over much of Dublin, making them well-known landmarks and some of the tallest structures in Ireland. History The Poolbeg power station is situated adjacent to the now-decommissioned Pigeon House generating station, where electricity was first generated in 1903 (with the distinction of being the ...

Dublin
Dublin (; , or ) is the capital and largest city of Republic of Ireland, Ireland. On a bay at the mouth of the River Liffey, it is in the Provinces of Ireland, province of Leinster, bordered on the south by the Dublin Mountains, a part of the Wicklow Mountains range. At the 2016 census of Ireland, 2016 census it had a population of 1,173,179, while the preliminary results of the 2022 census of Ireland, 2022 census recorded that County Dublin as a whole had a population of 1,450,701, and that the population of the Greater Dublin Area was over 2 million, or roughly 40% of the Republic of Ireland's total population. A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kings of Dublin, Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. The city expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Cycle Gas Turbine
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 64% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gas-fired Power Stations In The Republic Of Ireland
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

The Irish Times
''The Irish Times'' is an Irish daily broadsheet newspaper and online digital publication. It launched on 29 March 1859. The editor is Ruadhán Mac Cormaic. It is published every day except Sundays. ''The Irish Times'' is considered a newspaper of record for Ireland. Though formed as a Protestant nationalist paper, within two decades and under new owners it had become the voice of British unionism in Ireland. It is no longer a pro unionist paper; it presents itself politically as "liberal and progressive", as well as being centre-right on economic issues. The editorship of the newspaper from 1859 until 1986 was controlled by the Anglo-Irish Protestant minority, only gaining its first nominal Irish Catholic editor 127 years into its existence. The paper's most prominent columnists include writer and arts commentator Fintan O'Toole and satirist Miriam Lord. The late Taoiseach Garret FitzGerald was once a columnist. Senior international figures, including Tony Blair and Bill Cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pigeon House 1994
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pride (In The Name Of Love)
"Pride (In the Name of Love)" is a song by Irish rock band U2. It is the second track on the band's 1984 album, ''The Unforgettable Fire'', and was released as its lead single in September 1984. The song was produced by Brian Eno and Daniel Lanois.

Fossil Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned for heating, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dispatchable Generation
Dispatchable generation refers to sources of electricity that can be programmed ''on demand'' at the request of power grid operators, according to market needs. Dispatchable generators may adjust their power output according to an order. Non-dispatchable renewable energy sources such as wind power and solar photovoltaic (PV) power cannot be controlled by operators. Other types of renewable energy that are dispatchable without separate energy storage are hydroelectric, biomass, geothermal and ocean thermal energy conversion. Startup time Dispatchable plants have varying startup times. The fastest plants to dispatch are grid batteries which can dispatch in milliseconds. Hydroelectric power plants can often dispatch in tens of seconds to minutes and natural gas power plants can generally dispatch in tens of minutes. For example, the 1,728 MW Dinorwig pumped storage power plant can reach full output in 16 seconds. Gas turbine (Brayton cycle) thermal plants require around 15 ...

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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
