The steam engine

Inventors: Thomas Savery, Thomas Newcomen and James watt

Thomas Savery (1650-1715) English military engineer and inventor  and design who designed the first crude steam engine inspired from Denis Papin’s Digester or pressure cooker of 1679.

Thomas worked on solving of problems in pumping of water out of coal mines this machine consists of a closed vessel filled up with water were steam under pressure was introduced, witch forced the water up and out of the mine shaft.

Thomas Newcomen (1663-1729) English blacksmith, inventor of the atmospheric steam engine, an improvement over Thomas Savery’s design

The Newcomen’s engine focused on atmospheric pressure to push out the water from the mines. Steam was pumped into a cylinder, then the steam was condensed by cold water outside of the cylinder creating a vacuum on the inside of the cylinder.

James Watt (1736-1819) Scottish inventor and mechanical engineer renowned for the improvements made on the steam engine in 1765 while working in the uni of Glasgow Watt took the task of repairing the Newcomen engine.

James Watts added a separate condenser connecting to the cylinder, this design allowed the condenser to be cool while the cylinder remaining hot ,Watts’s engine soon Dominated England and replaced other steam engines and helped bring about the Industrial revolution
