Watt Steam Engine
The Watt steam engine design became synonymous with steam engines, and it was many years before significantly new designs began to replace the basic Watt design. The first steam engines, introduced by Thomas Newcomen in 1712, were of the "atmospheric" design. At the end of the power stroke, the weight of the object being moved by the engine pulled the piston to the top of the cylinder as steam was introduced. Then the cylinder was cooled by a spray of water, which caused the steam to condense, forming a partial vacuum in the cylinder. Atmospheric pressure on the top of the piston pushed it down, lifting the work object. James Watt noticed that it required significant amounts of heat to warm the cylinder back up to the point where steam could enter the cylinder without immediately condensing. When the cylinder was warm enough that it became filled with steam the next power stroke could commence. Watt realised that the heat needed to warm the cylinder could be saved by adding ...

Newcomen Steam Engine
The atmospheric engine was invented by Thomas Newcomen in 1712, and is often referred to as the Newcomen fire engine (see below) or simply as a Newcomen engine. The engine was operated by condensing steam drawn into the cylinder, thereby creating a partial vacuum which allowed the atmospheric pressure to push the piston into the cylinder. It was historically significant as the first practical device to harness steam to produce mechanical work. Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines. Hundreds were constructed throughout the 18th century. James Watt's later engine design was an improved version of the Newcomen engine that roughly doubled fuel efficiency. Many atmospheric engines were converted to the Watt design, for a price which was based on a fraction of the fuel-savings. As a result, Watt is today better known than Newcomen in relation to the origin of the steam engine. Precursors Prior to Newcomen a number of s ...

Broseley
Broseley is a market town in Shropshire, England, with a population of 4,929 at the 2011 Census and an estimate of 5,022 in 2019. The River Severn flows to its north and east. The first The Iron Bridge, iron bridge in the world was built in 1779 across the Severn, linking Broseley with Coalbrookdale and Madeley, Shropshire, Madeley. This contributed to the Industrial Revolution, early industrial development in the Ironbridge Gorge, which is now part of a World Heritage Site. History There was a settlement existing in 1086, listed as Bosle in the Domesday Book of that year, when it lay in the Hundred of Alnodestreu. That jurisdiction was dismembered in the time of King Henry I of England, Henry I, when Broseley and Willey, Shropshire, Willey were reassigned to the Munslow (hundred), Munslow Hundred. Finally they were transferred to the Liberty of Wenlock on its creation in the time of King Richard I of England, Richard I. The place name appears as ''Burewardeslega'' in 1177, and ...

John Wilkinson (industrialist)
John "Iron-Mad" Wilkinson (1728 – 14 July 1808) was an English industrialist who pioneered the manufacture of cast iron and the use of cast-iron goods during the Industrial Revolution. He was the inventor of a precision boring machine that could bore cast iron cylinders, such as cannon barrels and piston cylinders used in the steam engines of James Watt. His boring machine has been called the first machine tool. He also developed a blowing device for blast furnaces that allowed higher temperatures, increasing their efficiency, and helped sponsor the first iron bridge in Coalbrookdale. He is notable for his method of cannon boring, his techniques at casting iron and his work with the government of France to establish a cannon foundry. Biography Early life John Wilkinson was born in Little Clifton, Bridgefoot, Cumberland (now part of Cumbria), the eldest son of Isaac Wilkinson and Mary Johnson. Isaac was then the potfounder at the blast furnace there, one of the first to u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tipton
Tipton is an industrial town in the West Midlands in England with a population of around 38,777 at the 2011 UK Census. It is located northwest of Birmingham. Tipton was once one of the most heavily industrialised towns in the Black Country, with thousands of people employed in the town's industries. Its factories began closing in the 1970s and it has gradually become a commuter town, home largely to people working in other parts of the region. Historically within Staffordshire, the town is now in the borough of Sandwell, It is located adjacent to the towns of Dudley, Wednesbury, Moxley, Darlaston and Bilston. It is also located between Wolverhampton and Birmingham. It also incorporates the areas of Tipton Green, Ocker Hill, Dudley Port, Horseley Heath and Great Bridge. Tipton was an urban district until 1938, when it became a municipal borough. Much of the Borough of Tipton was transferred into West Bromwich County Borough in 1966, but parts of the old borough were a ...

Birmingham
Birmingham ( ) is a city and metropolitan borough in the metropolitan county of West Midlands in England. It is the second-largest city in the United Kingdom with a population of 1.145 million in the city proper, 2.92 million in the West Midlands metropolitan county, and approximately 4.3 million in the wider metropolitan area. It is the largest UK metropolitan area outside of London. Birmingham is known as the second city of the United Kingdom. Located in the West Midlands region of England, approximately from London, Birmingham is considered to be the social, cultural, financial and commercial centre of the Midlands. Distinctively, Birmingham only has small rivers flowing through it, mainly the River Tame and its tributaries River Rea and River Cole – one of the closest main rivers is the Severn, approximately west of the city centre.

Soho, Birmingham
Soho is an area that is in Central Birmingham and Smethwick, approximately 2 miles north west of Birmingham city centre on the A41. The name is an abbreviation of South House, denoting that it was located to the south of Handsworth. The section of the A41 separating Handsworth from Winson Green is known as Soho Road. Soho expanded dramatically during the 19th century with the construction of numerous houses and factories, and immigration from the Commonwealth was centred in these homes during the 1950s and 1960s. Most of the immigrants who settled in Soho were of Indian origin. Further housebuilding took place by the local council during the 1960s and 1970s. Soho falls partly in the Soho ward of the City of Birmingham and partly in the Soho and Victoria ward of the Borough of Sandwell. Soho ward, Birmingham Until 1911 the part now within Birmingham formed part of Handsworth District, and is now a ward within the council constituency of Ladywood. Demography The 2001 Popul ...

Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760mm Hg, 29.9212 inchesHg, or 14.696psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's gravi ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condenser (heat Transfer)
In systems involving heat transfer, a condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling. In so doing, the latent heat is released by the substance and transferred to the surrounding environment. Condensers are used for efficient heat rejection in many industrial systems. Condensers can be made according to numerous designs, and come in many sizes ranging from rather small (hand-held) to very large (industrial-scale units used in plant processes). For example, a refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems. Use of cooling water or surrounding air as the coolant is common in many condensers. History The earliest laboratory condenser, a " Gegenstromkühler" (counter-flow condenser), was invented in 1771 by the Swedish-German ...
