where was the steam engine invented industrial revolution
Steam power during the Industrial Revolution 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. Early versions used a soldered copper boiler which burst easily at low steam pressures. Later versions with iron boiler were capable of raising water about 46 meters (150 feet). The Savery engine 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 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.[1]
