During the Industrial Revolution, steam power replaced water power and muscle power (which often came from horses) as the primary source of power in use in industry. Its first use was to pump water from mines. The early engines were not very efficient, but a modified version created by James Watt gave engines the power to become a driving force behind the Industrial Revolution. Steam power was not only used in engines but also in furnaces and other factory appliances that were difficult to implement prior to the invention of steam power.

Overview

If iron was the key metal of the Industrial Revolution, the steam engine was perhaps the most important machine technology. Inventions and improvements in the use of steam for power began prior to the 18th century, as they had with iron. As early as 1689, English engineer Thomas Savery created a steam engine to pump water from mines. Thomas Newcomen, another English engineer, developed an improved version by 1712. Scottish inventor and mechanical engineer James Watt made the most significant improvements, allowing the steam engine to be used in many industrial settings, not just in mining. Early mills had run successfully with water power, but the advancement of using the steam engine meant that a factory could be located anywhere, not just close to water.

In 1775 Watt formed an engine-building and engineering partnership with manufacturer Matthew Boulton. This partnership became one of the most important businesses of the Industrial Revolution. Boulton & Watt served as a kind of creative technical center for much of the British economy. They solved technical problems and spread the solutions to other companies. Similar firms did the same thing in other industries and were especially important in the machine tool industry. This type of interaction between companies was important because it reduced the amount of research time and expense that each business had to spend working with its own resources. The technological advances of the Industrial Revolution happened more quickly because firms often shared information, which they then could use to create new techniques or products.

The development of the stationary steam engine was an essential early element of the Industrial Revolution, however it should be remembered that for most of the period of the Industrial Revolution the majority of industries still relied on wind and water power as well as horse and man-power for driving small machines.

Thomas Savery's engine

The industrial use of steam power started with Thomas Savery in 1698. He constructed and patented in London the first engine, which he called the "Miner's Friend" since he intended it to pump water from mines. This machine used steam at 8 to 10 atmospheres (120-150 psi) and had no moving parts other than hand-operated valves. The steam once admitted into the cylinder was first condensed by an external cold water spray, thus creating a partial vacuum which drew water up through a pipe from a lower level; then valves were opened and closed and a fresh charge of steam applied directly on to the surface of the water now in the cylinder, forcing it up an outlet pipe discharging at higher level. The engine generated about one horsepower (hp) and was used as a low-lift water pump in a few mines and numerous water works, but it was not a success since it was limited in pumping height and prone to boiler explosions.

Thomas Newcomen's engine

Newcomen's atmospheric steam engine

The first safe and successful power plant was the "atmospheric" steam engine driving a reciprocating mechanical pump introduced by Thomas Newcomen from 1712 onwards. The working principle of the engine appears to have been based on Papin's experiments carried out 20 years earlier and it was totally different from Savery's device, but as the latter had taken out a very wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing their engine until 1733 under a joint patent^[1]. Newcomen's engine employed a piston and cylinder, one end of which was open to the atmosphere above the piston. Steam just above atmospheric pressure (all that the boiler could stand) was introduced into the lower half of the cylinder beneath the piston during the gravity-induced upstroke; the steam was then condensed by a jet of cold water injected into the steam space to produce a partial vacuum; the pressure differential between the atmosphere and the vacuum on either side of the piston displaced it downwards into the cylinder, raising the opposite end of a rocking beam upon which was hung a gang of gravity-actuated reciprocating force pumps housed in the mineshaft. The engine's role was to produced a succession of power strokes which primed the pump. A number of these pumps were successfully put to use for draining mines in Britain, with the engine at the surface level (unlike Savery's pumps). They were large machines, requiring a lot of capital to build and install and were extremely inefficient by modern standards, producing about 5 hp and for a high fuel consumption; however when located at pit heads where coal was cheap, they opened up a great expansion in coal mining by allowing mines to be sunk deeper. Despite their disadvantages, Newcomen engines continued to be used in the coalfields until the early decades of the nineteenth century because they were reliable and easy to maintain.

By 1729, when Newcomen died, his engines had spread to France, Germany, Austria, Hungary and Sweden. A total of 110 are known to have been built by 1733 when the patent expired, of which 14 were abroad. A total of 1,454 engines had been built by 1800.

James Watt's engine

Steam engines remained fundamentally unchanged until by 1778, with the collaboration of Matthew Boulton, James Watt had succeeded in perfecting his Watt steam engine, which incorporated a series of radical improvements notably: closing off the upper part of the cylinder and making the low pressure steam drive the top of the piston instead of the atmosphere, use of a steam jacket and the celebrated separate steam condenser chamber. All this meant that engine efficiency was no longer susceptible to changeable atmospheric conditions and that a more constant temperature could be maintained in the cylinder; the improvements combined increased engine efficiency by about a factor of five saving 75% on coal costs.

Nor could the atmospheric engine be easily adapted to drive a rotating wheel, although Wasborough and Pickard did succeed in doing so towards 1780. However by 1783 the more economical Watt steam engine had been fully developed into a double-acting rotative type, which meant that it could be used to directly drive the rotary machinery of a factory or mill. Both of Watt's basic engine types were commercially very successful, and by 1800, the firm Boulton & Watt had constructed 496 engines, with 164 driving reciprocating pumps, 24 serving blast furnaces, and 308 powering mill machinery; most of the engines generated between 5 to 10 hp. The firm of Boulton & Watt, was initially a partnership between Matthew Boulton and James Watt, formed in 1775 to make steam engines at their Soho Foundry in Smethwick, near Birmingham, England. ...

The development of machine tools, such as the lathe, planing and shaping machines powered by these engines, enabled all the metal parts of the engines to be easily and accurately cut and in turn made it possible to build larger and more powerful engines.

Until about 1800, the most common pattern of steam engine was the beam engine, built as an integral part of a stone or brick engine-house, but soon various patterns of self-contained portative engines (readily removable, but not on wheels) were developed, such as the table engine.

Development after Watt

From 1799 the Cornish engineer, Richard Trevithick began to construct higher pressure non-condensing steam engines, exhausting against atmospheric pressure. This gave a much higher power/weight ratio allowing an engine and boiler to be combined into a single unit compact enough to be used on mobile road and rail locomotives and steam boats.

In the early 19th century after the expiration of Watt's patent, the steam engine underwent many improvements by a host of inventors and engineers.
