The company introduced high-pressure steam engines to the riverboat trade in the Mississippi watershed. The first high-pressure steam engine was invented in 1800 by Richard Trevithick. [44] The importance of raising steam under pressure (from a thermodynamic standpoint) is that it attains a higher temperature. Thus, any engine using high ...
A steam engine is a heat engine that performs 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. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
1790 (): Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. 1791 (): Edward Bull makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen's designs. About 10 of his engines are built in Cornwall.
Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

The history of thermodynamics is a fundamental strand in the history of physics, the history of chemistry, and the history of science in general. Due to the relevance of thermodynamics in much of science and technology, its history is finely woven with the developments of classical mechanics, quantum mechanics, magnetism, and chemical kinetics, to more distant applied fields such as ...
1679 – Denis Papin designed a steam digester which inspired the development of the piston-and-cylinder steam engine. 1694–1734 – Georg Ernst Stahl names Becher's combustible earth as phlogiston and develops the theory; 1698 – Thomas Savery patents an early steam engine [6]
Animation of a schematic Newcomen engine. – Steam is shown pink and water is blue. – Valves move from open (green) to closed (red) Thomas Newcomen (/ ˈ nj uː k ʌ m ə n /; February 1664 [i] [1] – 5 August 1729) was an English inventor who created the atmospheric engine, the first practical fuel-burning engine in 1712.
The theory was that, by removing around 600 of the 970 British thermal units present in each pound of steam (1400 of the 2260 kilojoules in each kilogram), it would be possible to return the exhaust steam to the boiler by a pump which would consume only 1–2% of the engine's power output.
