Archimede Project
Archimede combined cycle power plant (also known as Centrale a ciclo combinato Archimede, once Centrale Enel Priolo Gargallo) is an integrated solar combined cycle (ISCC) power generation plant at Priolo Gargallo near Syracuse in Sicily, Italy. The combine cycle section was inaugurated in 2003, and the solar field on 14 July 2010. The solar field is the first to use molten salt for heat transfer and storage which is integrated with the combined-cycle gas facility. It uses technology developed by ENEA and Archimede Solar Energy, a joint venture between Angelantoni Industrie and Siemens Energy. Archimede is owned and operated by Enel. The plant is called "Archimedes" (the famous resident of the nearby Magna Graecia Hellenistic city of Syracuse) after the rows of huge parabolic mirrors used to capture the sun's rays, which recall the "burning mirrors" that Archimedes is said to have used to set fire to the Roman ships besieging Syracuse during the Siege of Syracuse (214 ...

The Engineer (UK Magazine)
''The Engineer'' is a London-based monthly magazine and website covering the latest developments and business news in engineering and technology in the UK and internationally. History and description ''The Engineer'' was founded in January 1856. It was established by Edward Charles Healey, an entrepreneur and engineering enthusiast with financial interests in the railways whose friends included Robert Stephenson and Isambard Kingdom Brunel. The journal was created as a technical magazine for engineers. ''The Engineer'' began covering engineering including inventions and patents during a high point of British economic manufacturing power. In the 19th century it also published stock prices of raw materials. Together with the contemporary ''Engineering'' journal the work is considered a valuable historical resource for the study of British economic history. On 10 July 2012 the magazine announced its final print edition, the editor Jon Excell citing "increasing distribution and ...

Carbon Dioxide Emission
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by g ...

Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Gas-fired Power Plant
A gas-fired power plant or gas-fired power station or natural gas power plant is a thermal power station which burns natural gas to generate electricity. Natural gas power stations generate almost a quarter of world electricity and a significant part of global greenhouse gas emissions and thus climate change. However they can provide seasonal dispatchable generation to balance variable renewable energy where hydropower or interconnectors are not available. Basic concepts: heat into mechanical energy into electrical energy A gas-fired power plant is a type of fossil fuel power station in which chemical energy stored in natural gas, which is mainly methane, is converted successively into: thermal energy, mechanical energy and, finally, electrical energy. Although they cannot exceed the Carnot cycle limit for conversion of heat energy into useful work the excess heat may be used in cogeneration plants to heat buildings, produce hot water, or to heat materials on an industrial ...

Hellenistic Civilization
In Classical antiquity, the Hellenistic period covers the time in History of the Mediterranean region, Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC and the emergence of the Roman Empire, as signified by the Battle of Actium in 31 BC and the conquest of Ptolemaic Kingdom, Ptolemaic Egypt the following year. The Ancient Greek word ''Hellas'' (, ''Hellás'') was gradually recognized as the name of Greece, name for Greece, from which the word ''Hellenistic'' was derived. "Hellenistic" is distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all ancient territories under Greek influence, in particular the East after the conquests of Alexander the Great. After the Macedonian invasion of the Achaemenid Empire in 330 BC and its disintegration shortly after, the Hellenistic kingdoms were established throughout Southwest Asia, south-west Asia (Seleucid Empire, Attalid dynasty, Kingdom of Pe ...

Magna Graecia
Magna Graecia (, ; , , grc, Μεγάλη Ἑλλάς, ', it, Magna Grecia) was the name given by the Romans to the coastal areas of Southern Italy in the present-day Italian regions of Calabria, Apulia, Basilicata, Campania and Sicily; these regions were extensively populated by Greek settlers. These settlers, who began arriving in the 8th century BC, brought with them their Hellenic civilization, which left a lasting imprint on Italy (such as in the culture of ancient Rome). They also influenced the native peoples, such as the Sicels and the Oenotrians, who became hellenized after they adopted the Greek culture as their own. The Greek expression ''Megálē Hellás'', later translated into Latin as ''Magna Graecia,'' first appears in Polybius' '' Histories,'' where he ascribed the term to Pythagoras and his philosophical school. Strabo also used the term to refer to the size of the territory that had been conquered by the Greeks, and the Roman poet Ovid used the term in his p ...
