How it Works (cont.)

In earlier forms steam pressure and vacuums create a pump force

More modern steam engines use the same principles to drive a device to create powder

How it Works

Inventors

  • Thomas Savery →- steam pressure
  • Thomas Newcomen - vacuum
  • James Watt - separate condenser

Thomas Savery

Thomas Savery was an English military engineer.

In, 1698 he patented the first crude steam engine.

  • Improvement from the pressure cooker

Used to pump water out of coal mines

Significance of the Steam Engine

What Is the Steam Engine?

The steam engine is a heat engine designed to perform mechanical work by employing the power of steam, steam pressure and steam in fluid, to drive or produce mechanical motion

The History of the Steam Engine (cont.)

In 1775 James Watt improved upon Newcomen's design.

Fields of Engineering

Thomas Newcomen

In 1814 the first steam locomotive to run on rails wasbuilt by George Stephenson

The History of the Steam Engine (cont.)

Locomotion - Boats, Trains, Submarines

Steam Turbines - To generate electricity

Personal Steam generators

Pumps

Mechanical Engineering

In 1896 Stanley Steamers used a fire-tube boiler to power a two-cylinder engine that was more popular than conventional gas vehicles from 1899 to 1905

Thomas Newcomen was a blacksmith

Thomas Newcomen developed the first true commercial steam engine using a piston.

  • Atmospheric Engine
  • Pressure is near atmospheric

In 1769 the first vehicle to move under its own power was created, however it needed to stop every 15 minutes in order to build up power. On the first long trip which was around the entirety of Paris it crashed into a wall.

Industrial/Manufacturing Engineering

In 1814, English engineer George Stephenson built the first steam locomotive to actually run on rails. His later accomplishments include construction the world's first public railways

Chemical Engineering Loosely

The History of the Steam Engine

In the very first century Greek engineer, Hero of Alexandria designed the first steam engine. It had no practical use.

Electrical Engineering Loosely

In the Mid 1670's French Inventor Denis Papin built a cooker that trapped steam inside to build pressure. Later he designed a piston and cylinder concept using steam.

In 1712 Thomas Newcomen invented the atmospheric steam engine.

James Watt

James Watt improved upon the original steam engine

  • more efficient
  • more effective
  • could be used in factories

Principle of a separate condenser
