* Thomas Savery invented the first steam engine, which was a steam pump used to remove water from mines.
* It consisted of a boiler, a receiver, and a suction pipe.
* When the boiler was heated, steam would rise into the receiver and create a vacuum.
* The suction pipe would then draw water into the receiver, which would be discharged when the vacuum was released.
2. Newcomen's Atmospheric Engine (1712)
* Thomas Newcomen improved on Savery's steam engine by adding a piston and a cylinder.
* The piston was connected to a beam, which would move up and down as the piston moved in and out of the cylinder.
* The beam would then operate a pump, which would remove water from the mine.
* Newcomen's atmospheric engine was much more efficient than Savery's steam pump, and it was widely used in mines and other industries.
3. Watt's Steam Engine (1769)
* James Watt made a number of improvements to Newcomen's atmospheric engine, including the addition of a condenser and a rotary motion.
* The condenser allowed the steam to be cooled and condensed back into water, which increased the efficiency of the engine.
* The rotary motion allowed the engine to be used to drive machinery, such as mills and factories.
* Watt's steam engine was a major breakthrough in the development of the Industrial Revolution.
4. High-Pressure Steam Engine (1800)
* Richard Trevithick developed the high-pressure steam engine, which could operate at much higher pressures than previous steam engines.
* This allowed the engine to be much more powerful and compact, making it ideal for use in locomotives and ships.
* The high-pressure steam engine was a major factor in the development of the transportation industry.
5. Steam Turbine (1884)
* The steam turbine was invented by Sir Charles Parsons, and it was a major improvement over the reciprocating steam engine.
* The steam turbine used a series of blades to convert the energy of steam into rotational motion.
* The steam turbine was much more efficient and compact than the reciprocating steam engine, and it was widely used in power plants and ships.
6. Modern Steam Engine
* Modern steam engines are used in a variety of applications, including power generation, marine propulsion, and industrial processes.
* They are typically large-scale engines that operate at high pressures and temperatures.
* Modern steam engines are highly efficient and reliable, and they play an important role in the global economy.
