Steam Engines
A steam engine is a heat engine that performs Work (physics), mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a Cylinder (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including Boiler (power generation), boilers etc.), such as railway steam locomot ...

External Combustion Engine
An external combustion engine (EC engine) is a Reciprocating engine, reciprocating heat engine where a working fluid, contained internally, is heated by combustion in an external source, through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism (engineering), mechanism of the engine, produces motion and usable Mechanical work, work. The fluid is then dumped (open cycle), or cooled, compressed and reused (closed cycle). In these types of engines, the combustion is primarily used as a heat source, and the engine can work equally well with other types of heat sources. Combustion "Combustion" refers to burning fuel with an oxidizer, to supply the heat. Engines of similar (or even identical) configuration and operation may use a supply of heat from other sources such as nuclear, solar, geothermal or exothermic reactions not involving combustion; they are not then strictly classed as external combustion engines, but as external thermal eng ...

Industrial Revolution
The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a transitional period of the global economy toward more widespread, efficient and stable manufacturing processes, succeeding the Second Agricultural Revolution. Beginning in Kingdom of Great Britain, Great Britain around 1760, the Industrial Revolution had spread to continental Europe and the United States by about 1840. This transition included going from craft production, hand production methods to machines; new Chemical industry, chemical manufacturing and Puddling (metallurgy), iron production processes; the increasing use of Hydropower, water power and Steam engine, steam power; the development of machine tools; and rise of the mechanisation, mechanised factory system. Output greatly increased, and the result was an unprecedented rise in population and population growth. The textile industry was the first to use modern production methods, and textiles b ...

James Watt
James Watt (; 30 January 1736 (19 January 1736 OS) – 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. At the time engineers such as John Smeaton were aware of the inefficiencies of Newcomen's engine and aimed to improve it. Watt's insight was to realise that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually, he adapted his engine to produce rot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Newcomen
Thomas Newcomen (; February 1664 – 5 August 1729) was an English inventor, creator of the Newcomen atmospheric engine, atmospheric engine in 1712, Baptist lay preacher, preacher by calling and ironmonger by trade. He was born in Dartmouth, Devon, Dartmouth, in Devon, England, to a merchant family and baptized at St. Saviour's Church on 28 February 1664. In those days, flooding in coal and tin mines was a major problem. Newcomen was soon engaged in trying to improve ways to pump out the water from such mines. His ironmonger's business specialised in designing, manufacturing and selling tools for the mining industry. Religious life Thomas Newcomen was a lay preacher and a teaching elder in the local Baptist church. After 1710, he became the pastor of a local group of Baptists. His father had been one of a group who brought the well-known Puritan minister John Flavel to Dartmouth. Later one of Newcomen's business contacts in London, Edward Wallin, was another Baptist mi ...

Thomas Savery
Thomas Savery (; c. 1650 – 15 May 1715) was an English inventor and engineer. He invented the first commercially used steam-powered device, a steam pump which is often referred to as the "Savery engine". Savery's steam pump was a revolutionary method of pumping water, which improved mine drainage and made widespread public water supply practicable. Career Thomas Savery was born at the manor house of Shilstone, near Modbury, Devon. He became a military engineer, rising to the rank of captain by 1702, and spent his free time performing experiments in mechanics. In 1696 he took out a patent for a machine for polishing glass or marble and another for "rowing of ships with greater ease and expedition than hitherto been done by any other" which involved paddle-wheels driven by a capstan and which was dismissed by the Admiralty following a negative report by the Surveyor of the Navy, Edmund Dummer. Savery also worked for the Sick and Hurt Commissioners, contracting the su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stationary Steam Engine
Stationary steam engines are fixed steam engines used for pumping or driving mills and factories, and for power generation. They are distinct from locomotive engines used on railways, traction engines for heavy steam haulage on roads, steam cars (and other motor vehicles), agricultural engines used for ploughing or threshing, marine engines, and the steam turbines used as the mechanism of power generation for most nuclear power plants. They were introduced during the 18th century and widely made for the whole of the 19th century and most of the first half of the 20th century, only declining as electricity supply and the internal combustion engine became more widespread. Types of stationary steam engine There are different patterns of stationary steam engines, distinguished by the layout of the cylinders and crankshaft: * Beam engines have a rocking beam providing the connection between the vertical cylinder and crankshaft. * Table engines have the crosshead above the v ...

Beam Engine
A beam engine is a type of steam engine where a pivoted overhead Beam (structure), beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt, who added a separate Condenser (heat transfer), condenser; Jonathan Hornblower and Arthur Woolf, who Compound steam engine, compounded the cylinders; and William McNaught (Glasgow), William McNaught, who devised a method of compounding an existing engine. Beam engines were first used to pump water out of mines or into canals but could be used to pump water to supplement the flow for a waterwheel powering a watermill, mill. The rotative beam engine is a later design of beam engine where the connecting rod drives a flywheel by means of a Crank (mechanism), crank (or, historically, by means of ...

Portable Engine
A portable engine is an engine, either a steam engine or an internal combustion engine, that sits in one place while operating (providing power to machinery), but (unlike a stationary engine) is wikt:portable#Adjective, portable and thus can be easily moved from one work site to another. Mounted on wheels or skids, it is either towed to the work site or moves there via self-propulsion. Portable engines were in common use in industrialised countries from the early 19th through early 20th centuries, during an era when power transmission#Mechanical power, mechanical power transmission was widespread. Before that, most power generation and transmission were by working animal, animal, watermill, water, windmill, wind, or manual labour, human; after that, a combination of electrification (including rural electrification) and modern vehicles and equipment (such as tractors, trucks, automobile, cars, engine-generators, and machines with their engines built in) displaced most use of porta ...
