Used early on in electrical generation and to power ships, turbines were bladed wheels that created rotary motion when high pressure steam was passed through them. The efficiency of large steam turbines was considerably better than the best compound engines , while also being much simpler, more reliable, smaller and lighter all at the same time.
Steam engines remained the dominant source of power until the early 20th century, when advances in the design of the steam turbine, electric motors, and internal combustion engines gradually resulted in the replacement of reciprocating (piston) steam engines, with merchant shipping relying increasingly upon diesel engines, and warships on the ...
Obsolete technology Replacement Still used for Bathing machine: No longer required due to changing social standards of morality Hourglass: Clock: Tasks where a fixed amount of time can be measured with a low-tech solution: Exposure time tracker in saunas (where electronics might be damaged by the heat or ultraviolet light); retro kitchen timers, board games, other short-term timers.
At the end of this power stroke, the steam valve was reopened, and the weight of the pump rods pulled the beam down, lifting the piston and drawing steam into the cylinder again. Using the piston and beam allowed the Newcomen engine to power pumps at different levels throughout the mine, as well as eliminating the need for any high-pressure steam.
The last engines of the classes 23.10, 65.10 and 50.40 were retired in the late 1970s, with some units older than 25 years. Some of the narrow-gauge locomotives are still in service for tourism purposes. Later, during the early 1960s, the DR developed a way to reconstruct older locomotives to conform with
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.
Train enthusiasts and history buffs alike will soon have a new Southeast Asian destination, as Vietnam prepares to unveil a revamped pair of vintage steam locomotives from the 1960s.
