Smokestack
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the ''flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term '' smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of a chimney i ...

Smokestack Industry
{{short description, Pollution-generating basic industry A smokestack industry is a basic, usually cyclical, heavy industry. The factories stereotypically used in such industries have smoke stacks, hence the name, and produce a high volume of pollution. Example industries include: *Iron and steelworks * Automotive * Chemical * Power generation History Smokestacks were first used during Industrial Revolution between the 18th and 19th centuries and were known to foul the airs in most larger cities but were most noted in large industrial centers like Manchester England or Pittsburgh Pennsylvania. During the dramatic growth and evolution of systems used to produce electricity coal burning central electric stations that relied on direct current were found throughout cities that released noxious fumes and soot into the city air. Taller smokestacks helped to reduce this environmental Environment most often refers to: __NOTOC__ * Natural environment, referring respectively to all li ...

Funnel (ship)
A funnel is the smokestack or chimney on a ship used to expel boiler steam and smoke or engine exhaust gas, exhaust. They are also commonly referred to as stacks. Purpose The primary purpose of a ship's funnel(s) is to lift the exhaust gases clear of the deck, in order not to foul the ship's structure or decks, and to avoid impairing the ability of the crew to carry out their duties. In steam ships the funnels also served to help induce a boiler draught, convection draught through the boilers. Design Since the introduction of steam-power to ships in the 19th century, the funnel has been a distinctive feature of the silhouette of a vessel, and used for recognition purposes. Funnel area The required funnel cross-sectional area is determined by the volume of exhaust gases produced by the propulsion plant. Often this area is too great for a single funnel. Early steam vessels needed multiple funnels ( had 5 when launched), but as efficiency increased new machinery needed fewe ...

Chimney (locomotive)
The chimney (smokestack or stack in American and Canadian English) is the part of a steam locomotive through which smoke leaves the boiler. As well, steam locomotive exhaust systems typically vent cylinder steam exhaust through the chimney, to enhance the draught through the boiler. Chimneys are designed to carry the exhaust steam and smoke clear of the driver's line of sight while remaining short enough to clear overhead structures. Some chimneys included apparatus to suppress the dispersal of sparks. Function The chimney was usually located at the leading end of the locomotive, above the smokebox, furthest away from the driver's cab and firebox. The earliest locomotive chimneys were typically tall enough to sustain temperature-induced density difference draught through a fire-tube boiler while the locomotive was stationary. However, following the example of Richard Trevithick's first locomotive in 1804, most designs diverted steam cylinder exhaust upward through the chimney ...

Tudor Style Architecture
The Tudor architectural style is the final development of medieval architecture in England and Wales, during the Tudor period (1485–1603) and even beyond, and also the tentative introduction of Renaissance architecture to Britain. It followed the Late Gothic Perpendicular style and, gradually, it evolved into an aesthetic more consistent with trends already in motion on the continent, evidenced by other nations already having the Northern Renaissance underway Italy, and especially France already well into its revolution in art, architecture, and thought. A subtype of Tudor architecture is Elizabethan architecture, from about 1560 to 1600, which has continuity with the subsequent Jacobean architecture in the early Stuart period. In the much more slow-moving styles of vernacular architecture, "Tudor" has become a designation for half-timbered buildings, although there are cruck and frame houses with half-timbering that considerably predate 1485 and others well after 160 ...

Gothic Architecture
Gothic architecture is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High Middle Ages, High and Late Middle Ages, surviving into the 17th and 18th centuries in some areas. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. It originated in the Île-de-France and Picardy regions of northern France. The style at the time was sometimes known as ''opus Francigenum'' (); the term ''Gothic'' was first applied contemptuously during the later Renaissance, by those ambitious to revive the Classical architecture, architecture of classical antiquity. The defining design element of Gothic architecture is the Pointed arch (architecture), pointed arch. The use of the pointed arch in turn led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows. At the Abbey of Basilica of Saint-Denis, Saint-Denis, near Paris, the choir was rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chimney Sweep
A chimney sweep is a person who inspects then clears soot and creosote from chimneys. The chimney uses the pressure difference caused by a hot column of gas to create a draught and draw air over the hot coals or wood enabling continued combustion. Chimneys may be straight or contain many changes of direction. During normal operation, a layer of creosote builds up on the inside of the chimney, restricting the flow. The creosote can also catch fire, setting the chimney (and potentially the entire building) alight. The chimney must be swept to remove the soot. In Great Britain, master sweeps took apprentices, typically workhouse or orphan boys, and trained them to climb chimneys. In the German States, master sweeps belonged to trade guilds and did not use climbing boys. In Italy, Belgium, and France, climbing boys were used. The occupation requires some dexterity, and carries health risks. History The Tudors in England had established the risk of chimneys and an ordinance w ...

Georgian Architecture
Georgian architecture is the name given in most English-speaking countries to the set of architectural styles current between 1714 and 1830. It is named after the first four Monarchy of the United Kingdom, British monarchs of the House of Hanover, George I of Great Britain, George I, George II of Great Britain, George II, George III, and George IV, who reigned in continuous succession from August 1714 to June 1830. The Georgian cities of the British Isles were Edinburgh, Bath, Somerset, Bath, pre-independence Georgian Dublin, Dublin, and London, and to a lesser extent York and Bristol. The style was revived in the late 19th century in the United States as Colonial Revival architecture and in the early 20th century in Great Britain as Neo-Georgian architecture; in both it is also called Georgian Revival architecture. In the United States, the term ''Georgian'' is generally used to describe all buildings from the period, regardless of style; in Britain it is generally restricte ...

Lead
Lead () is a chemical element; it has Chemical symbol, symbol Pb (from Latin ) and atomic number 82. It is a Heavy metal (elements), heavy metal that is density, denser than most common materials. Lead is Mohs scale, soft and Ductility, malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its Amphoterism, amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Lead compounds, Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited ...
