Who Invented the First Steam Engine and In What Year?

Who invented the first steam engine and in what year? Steam engines were probably the biggest boost towards the industrial revolution of the time. There were other events and inventions that helped the revolution along the way, but the steam engine had to be the biggest. The definition of the steam engine is a device that uses steam in a way to help accomplish work. So, read on if you want to know who invented the first steam engine and in what year.

Looking back into history, it is apparent that there were rudimentary forms of steam engines in use as far back as about 2000 years ago. However, for practical purposes the first steam engine was invented in 1689 by Thomas Savery.

Savery was an English engineer and built the engine to pump water from the depths of mines. By removing the water that collected at the bottom of mines, the engine allowed the mine to go deeper. The first steam engine was not very efficient but over the next 23 years, Thomas Newcomen, an English engineer, improved upon the design. 

Improvements to the Steam Engine

A Scottish inventor and mechanical engineer, James Watt, made a number of improvements that allowed the steam engine to better be applied to industrial applications.

The best known improvement to the Newcomen design was the separation of the condenser from the steam cylinder. By separating the condenser from the cylinder, the two could be kept at different temperatures during the operation of the engine.

Keeping the cylinder at a high temperature at all times improved the efficiency of the steam generation section of the engine, while keeping the condenser at a lower temperature improved its efficiency in the conversion of steam back into water.

The overall improvement of the engine’s efficiency contributed to the wide acceptance of the revisions made to the steam engine by Watt.

Use of Steam Engines

Although the invention of the steam engine is credited to James Watt, his invention was merely an improvement on the designs of Savery and Newcomen. The steam engine, as created by these men, was used in many types of industrial applications.

The steam engine's benefits ranged from applications in mobility to advances in manufacturing. The steam locomotive greatly enhanced the movement of people and cargo over land and the advent of the steam engine created the ability to convey people and cargo across bodies of water.

Some of the most picturesque examples of steam ships were the steamboats of the Mississippi River. The engine was used to supply the power for the paddlewheels of these majestic boats that virtually ran the economy of the River during the better part of the 19th Century.

One other very important application of the steam engine was in the generation of electricity by use of steam turbines. More than 80 percent of the world’s electricity is provided by steam turbines that are based on the steam engine. Steam turbine technology is also responsible for the propulsion in most nuclear powered ships and submarines.

Dangers in Steam Engines

There are distinct dangers involved in the steam engine principles. Most of these dangers manifested themselves in the early days of steam engine applications.

The cylinders used to heat the water to the boiling point and contain the steam for use as a power generator are closed vessels that must maintain integrity during the operation and containment of the steam. If the cylinder develops a defect in the integrity of the walls, joints or valves a rupture, can be explosive in nature and cause extensive damage to property and people.

Other safety issues that are of concern include the lack of water supply to the boiler, which can lead to vessel failure, release of steam from the system that leads to scalding of workers and over pressurization of the boiler which can lead to explosion.

The most notable device of the industrial revolution was the steam engine. It drove new developments and inventions by providing the power necessary for many applications in the industrial environment. Therefore, now that you know who invented the first steam engine and in what year, you can appreciate your trips on steam locomotives all that much more.
