Heron of Alexandria invented a steam powered rotating ball in Circa 100 AD. This is the first recorded steam power.
Thomas Savery (1650-1715) was an English military engineer and inventor who in 1698, took out a general patent covering all possible means of pumping water by steam power. It was based on Denis Papin's Digester or pressure cooker of 1679.
Thomas Savery had been working on solving the problem of pumping water out of coal mines, his machine consisted of a closed vessel filled with water into which steam under pressure was introduced. This forced the water upwards and out of the mine shaft. Then a cold water sprinkler was used to condense the steam. This created a vacuum which sucked more water out of the mine shaft through a bottom valve.
Thomas Savery later worked with Thomas Newcomen who had actually invented the atmospheric steam engine and had to share his success with the patent holder.
The first steam engine was invented by Thomas Newcomen in 1712 to pump water from mine, the first being installed in 1712 close to Dudley castle in the Black Country.. Later improvements were made by James Watt And Richard Trevithick.
richard trevithithick made one of the earliest steam locomotives: locomotion. whi cwheels made it so it derailed quite frequently. robert stevenson made another called the rocket and has taken much credit for the invention of the steam valve but it was the engineer of sans parell timothy hackworth who invented it.
William Symington invented Efficient Steam Navigation. He was a native of Leadhills, Lancashire and Scotland.
watch mark williams on the rails for more information or go to beamish open air museum where you can ride on a replica of the locomotives of that day.

From Wikipedia: The first steam device, the aeolipile, was invented by Heron of Alexandria, a Greek, in the 1st century AD, but used only as a toy. Incidently 700 years earlier in Corinth, Greece, rail tracks were invented; however the Greeks never thought of putting the two together.
In 1690, Denis Papin, a French physicist, built a working model of a steam engine after observing steam escaping from his pressure cooker in about 1679. Sir Samuel Morland also developed ideas for a steam engine during the same period. Early industrial steam engines were designed by Thomas Savery (1698), Thomas Newcomen (1712), and James Watt (patented in 1769), each adding new refinements. Humphrey Gainsborough produced a model condensing steam engine in the 1760s. In 1802 William Symington built the "first practical steamboat", and in 1807 Robert Fulton used the Watt steam engine to power the first commercially successful steamboat.

Thomas Savery was an English military engineer and inventor who in 1698, patented the first crude steam engine, based on Denis Papin's Digester or pressure cooker of 1679.

Thomas Savery later worked with Thomas Newcomen on the atmospheric steam engine. Among Savery's other inventions was an odometer for ships, a device that measured distance traveled.
Invention of Steam Engine
As with many inventions, there are is no simple answer.
Thomas Newcomen (1664-1729) is often regarded as the inventor, but he worked in partnership with Thomas Savery (c. 1760-1715), who had already built a steam 'engine' of sorts in 1698. However, as Savery's invention had no moving parts it's seldom counted as an engine. The first steam engine with moving parts was built in 1712 and was designed purely to pump water out of mines.
The early steam engines were inefficient and wasted a lot of fuel. James Watt (1736-1819), who was for many years instrument maker to the University of Glasgow, made significant improvements from 1776 onwards.
Key features of these improvements included (1) greatly raising the pressure in the boiler, which increased efficiency, and (2) producing circular motion. Watts' steam engines were suitable for use in factories and for a variety of purposes.
Important later developments include the steam locomotive and the steam-powered ship
