+ | ====== Early examples ====== | ||
+ | |||
+ | *~130 BC: [[Hero of Alexandria]] describes the [[aeolipile]], | ||
+ | *[[1551]]: [[Taqi al-Din]] describes a [[steam turbine]]-like device for rotating a spit. | ||
+ | *[[1601]]: [[Giovanni Battista della Porta]] performs experiments on using steam to create pressure or a vacuum. | ||
+ | *[[1615]]: [[Salomon de Caus]], who had been an engineer and architect under [[Louis XIII of France|Louis XIII]], publishes a book showing a device similar to that of Porta. | ||
+ | *[[1629]]: [[Giovanni Branca]] suggests using a steam [[turbine]] device similar to that described by Taqi al-Din but intended to be used to power a series of pestles working in mortars. | ||
+ | *[[1630]]: [[David Ramsey]] is granted a patent for various steam applications, | ||
+ | |||
+ | ======Towards a workable steam engine====== | ||
+ | *[[1663]]: [[Edward Somerset, 2nd Marquis of Worcester]], | ||
+ | *[[1698]]: [[Thomas Savery]] introduces a steam pump he calls the Miner' | ||
+ | *c.[[1705]]: | ||
+ | *[[1707]]: [[Denis Papin]] publishes a study on steam power, including a number of ideas. One uses a Savery-like engine to lift water onto a [[water wheel]] for rotary power. The study also proposes replacing the water of a Savery engine with a piston, which is pulled on by the vacuum in a cylinder after steam inside is condensed, but he was unable to build the device. | ||
+ | *1718: Desaguliers introduces an improved version of the Savery engine, which includes safety valves and a two-way valve that operated both the steam and cold water (as opposed to two separate valves). | ||
+ | *[[1720]]: Leupold designs an engine based on expansion, which he attributes to Papin, in which two cylinders alternately receive steam and then vent to the atmosphere. Although likely a useful design, it appears none were built. | ||
+ | |||
+ | ======The Newcomen Engine: Steam power in practice====== | ||
+ | *[[1712]]: [[Newcomens dampmaskine|Newcomen]] installs his first commercial engine < | ||
+ | *[[1713]]: [[Humphrey Potter]], a boy charged with operating a Newcomen engine, installs a simple system to automatically open and close the operating valves. The engine can now be run at 15 strokes a minute with little work other than firing the boiler. | ||
+ | *[[1718]]: [[Henry Beighton]] introduces an improved and much more reliable version of Potter' | ||
+ | *[[1733]] Newcomen' | ||
+ | *[[1769]]: [[John Smeaton]] experiments with Newcomen engines, and also starts building improved engines with much longer piston stroke than previous practice. Later engines, which marked probably the high point of Newcomen engine design, deliver up to 80 horsepower (around 60 kW). | ||
+ | *[[1775]]: By this date about 600 Newcomen engines erected in the UK. | ||
+ | *[[1779]]: The crank first applied by [[James Pickard]] to a Newcomen engine, producing rotary motion. | ||
+ | *[[1780]]-[[1800]]: | ||
+ | |||
+ | ======Watt' | ||
+ | *[[1765]]: [[James Watt]] hits on the idea of the separate condenser, the key being to relocate the water jet, (which condenses the steam and creates the vacuum in the Newcomen engine) inside an additional cylindrical vessel of smaller size enclosed in a water bath; the still-warm condensate is then evacuated into a hot well by means of a suction pump allowing the preheated water to be returned to the boiler. This greatly increases thermal efficiency by ensuring that the main cylinder can be kept hot at all times, unlike in the Newcomen engines where the condensing water spray cooled the cylinder at each stroke. Watt also closes off the top of the cylinder causing steam at a pressure marginally above that of the atmosphere to act on top of the piston against the vacuum created beneath it (in this sense Watt might be said to have " | ||
+ | *[[1765]]: [[Matthew Boulton]] opens the [[Soho Manufactory]] engineering works in [[Handsworth, | ||
+ | *[[1769]]: [[James Watt]] is granted a patent on his improved design. The increase in efficiency is enough for Watt and his partner [[Matthew Boulton]] to license the design based on the savings in coal per year, as opposed to a fixed fee. In the past this development has erroneously been characterised as marking the start of the [[Industrial Revolution]]< | ||
+ | *[[1775]]: Watt and Boulton enter into a formal partnership. | ||
+ | *[[1776]]: First commercial Boulton and Watt engine built. At this stage and until 1795 B&W only provided designs, plans, the most complicated engine parts and support with on-site erection. | ||
+ | *[[1781]]: [[Jonathan Hornblower]] patents a two-cylinder " | ||
+ | *[[1782]]: | ||
+ | *[[1783]]: Watt builds his first " | ||
+ | *[[1791]]: [[William Bull]] makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen' | ||
+ | *[[1799]]: [[Richard Trevithick]] builds his first high-pressure engine at [[Dolcoath mine|Dolcoath tin mine]] in Cornwall. | ||
+ | *[[1800]]: Watt's patent expires. | ||

+ | *[[1849]]: [[George Henry Corliss]] develops and markets the [[Corliss steam engine|Corliss-type steam engine]], a four-valve counterflow engine with separate steam admission and exhaust valves. | ||
+ | *[[1854]]: John Ramsbottom publishes a report on his use of oversized steel piston rings which maintain a seal by outward spring tension on the cylinder wall. This allows much better sealing (compared to earlier cotton seals) which leads to significantly higher system pressures before " | ||
+ | *[[1865]]: [[Auguste Mouchout]] invents the first device to convert [[solar energy]] into mechanical steam power, using a cauldron filled with water enclosed in glass, which would be put in the sun to boil the water. | ||
