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 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.
Newcomen's steam-powered atmospheric engine was the first practical piston steam engine; subsequent steam engines were to power the Industrial Revolution. The development of the stationary steam engine was an important element of the Industrial Revolution; however, during the early period of the Industrial Revolution, most industrial power was ...
Steam engines of this kind propelled the Industrial Revolution in Great Britain and the world. The Watt steam engine design was an invention of James Watt that became synonymous with steam engines during the Industrial Revolution, and it was many years before significantly new designs began to replace the basic Watt design.
Improvements in steam efficiency, like triple-expansion steam engines, allowed ships to carry much more freight than coal, resulting in greatly increased volumes of international trade. Higher steam engine efficiency caused the number of steam engines to increase several fold, leading to an increase in coal usage, the phenomenon being called ...
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 ...

Thomas Savery (/ ˈ s eɪ v ər i /; c. 1650 – 15 May 1715) was an English inventor and engineer.He invented the first commercially used steam-powered device, a steam pump [1] which is often referred to as the "Savery engine".
