Resolution (beam Engine)
''Resolution'' was an early beam engine, installed between 1781–1782 at Coalbrookdale as a water-returning engine to power the blast furnaces and ironworks there. It was one of the last water-returning engines to be constructed, before the rotative beam engine made this type of engine obsolete. Water power in Coalbrookdale Coalbrookdale was a cradle of the First Industrial Revolution and was the scene of Abraham Darby's first production of iron by a coke-fired blast furnace, rather than the previous and expensive charcoal. Coalbrookdale is a narrow steep-sided valley that offered useful water power to drive the furnace blast and the various stamp mills, boring engines, etc. Contemporary visitors commented upon the picturesque 'fine cascades' of water. Although the water power available at Coalbrookdale had been described as 'abundant', it was also seasonal: in the summer months, the lack of water could require the furnace to be 'blown out' for some months and work susp ...

Newcomen 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 smal ...

Cold Blast
Cold blast, in ironmaking, refers to a metallurgical furnace where air is not preheated before being blown into the furnace. This represents the earliest stage in the development of ironmaking. Until the 1820s, the use of cold air was thought to be preferable to hot air for the production of high-quality iron; this effect was due to the reduced moisture in cool winter air. The discovery by James Beaumont Neilson in about 1825 of the beneficial effects of the hot blast led to the rapid obsolescence of cold blast ironworks in Great Britain, where hot blast was in general use by 1835. Cold blast ironworks survived longer in the United States, but the use of hot blast as a method of smelting iron with anthracite was introduced in 1836, and the increasing US production of coke gradually drove out the cold blast furnaces. However, one of the last known operating cold blast charcoal Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other anim ...

Single-acting Cylinder
In mechanical engineering, the cylinders of reciprocating engines are often classified by whether they are single- or double-acting, depending on how the working fluid acts on the piston. Single-acting A single-acting cylinder in a reciprocating engine is a cylinder in which the working fluid acts on one side of the piston only. A single-acting cylinder relies on the load, springs, other cylinders, or the momentum of a flywheel, to push the piston back in the other direction. Single-acting cylinders are found in most kinds of reciprocating engine. They are almost universal in internal combustion engines (e.g. petrol and diesel engines) and are also used in many external combustion engines such as Stirling engines and some steam engines. They are also found in pumps and hydraulic rams. Double-acting A double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. In order to connect the piston in a double-acting cylinder to an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt's Separate Condenser
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 addin ...

Abraham Darby III
Abraham Darby III (24 April 1750 – 1789) was an English ironmaster and Quaker. He was the third man of that name in several generations of an English Quaker family that played a pivotal role in the Industrial Revolution. Life Abraham Darby was born in Coalbrookdale, Shropshire, in 1750, the eldest son of Abraham Darby the Younger (1711–1763) by his second wife, Abiah Maude, and educated at a school in Worcester kept by a Quaker named James Fell. At age thirteen, Darby inherited his father's shares in the family iron-making businesses in the Severn Valley, and in 1768, aged eighteen, he took over the management of the Coalbrookdale ironworks. He took various measures to improve the conditions of his work force. In times of food shortage he bought up farms to grow food for his workers, he built housing for them, and he offered higher wages than were paid in other local industries, including coal-mining and the potteries. He built the largest cast iron structure of his era ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abraham Darby IV
Abraham Darby IV (30 March 1804 – 28 November 1878) was an English ironmaster. He was born in Dale House, Coalbrookdale, Shropshire the son of Edmund Darby, a member of the Darby ironmaking family and Lucy (née Burlingham) Darby. He was a great-nephew of Abraham Darby III. In 1830, he and his brother Alfred took over the management of the Horsehay foundry, one of several foundries owned by the family business, and set about re-establishing the Coalbrookdale Company's reputation by investing in new technology there for the manufacture of wrought iron. In 1844, he became a major shareholder in the Ebbw Vale ironworks in South Wales. After a series of family disagreements, he resigned his management of the Coalbrookdale Company in 1849, and, in 1851, bought Stoke Court, Stoke Poges in Buckinghamshire, and moved to live there. He also rented property at Treberfydd in Breconshire, Wales. He acted as a Justice of the Peace in both counties, and, in 1853, was appointed High Sherif ...

Metallurgical Coal
Metallurgical coal or coking coal is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply. Metallurgical coal comes mainly from Canada, the United States, and Australia, with Australia exporting 58% of seaborne trade, mostly going to China. In the United States, the electric power sector used "93% of total U.S. coal consumption between 2007 and 2018"; only 7% of the total was metallurgical coal and coal for other uses such as heating. Characteristics Metallurgical coal is low in ash, moisture, sulfur and phosphorus content, and its rank is usually bituminous. Some grades of anthracite coal are used for sintering, pulverized coal injection, direct blast furnace charge, pelletizing ...

Horse Gin
A horse mill is a mill, sometimes used in conjunction with a watermill or windmill, that uses a horse engine as the power source. Any milling process can be powered in this way, but the most frequent use of animal power in horse mills was for grinding grain and pumping water. Other animal engines for powering mills are powered by dogs, donkeys, oxen or camels. Treadwheels are engines powered by humans. History The donkey or horse-driven rotary mill was a 4th-century BC Carthaginian invention, with possible origins in Carthaginian Sardinia. Two Carthaginian animal-powered millstones built using red lava from Carthaginian-controlled Mulargia in Sardinia were found in a 375–350 BC shipwreck near Mallorca. The mill spread to Sicily, arriving in Italy in the 3rd century BC. The Carthaginians used hand-powered rotary mills as early as the 6th century BC, and the use of the rotary mill in Spanish lead and silver mines may have contributed to the rise of the larger, animal-powered ...

Abraham Darby II
Abraham Darby, in his lifetime called Abraham Darby the Younger, referred to for convenience as Abraham Darby II (12 May 1711 – 31 March 1763) was the second man of that name in an English Quaker family that played an important role in the early years of the Industrial Revolution. Life Darby was born in Coalbrookdale, Shropshire to Abraham and Mary (née Sergeant). He followed in his father's footsteps(Abraham Darby I) in the Darby foundry business in Coalbrookdale, producing cast iron cooking pots, kettles, and other goods. The Coalbrookdale Company also played an important role in using iron to replace the more expensive brass for cylinders for Thomas Newcomen's steam engines. He and his partners were responsible for a very important innovation in introducing the use of coke pig iron as the feedstock for finery forges. This formed a significant part of the output of Horsehay and Ketley Furnaces, which they built in the late 1750s. His father's successful use of coke pig ...
