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.
By the 1960s, twelve roads still ran into the shed area, but the six most western lines had the overall roofing removed by then. [10] As the drawdown of steam took place in the late 1960s, steam engines from the Leeds and Bradford area were sent to Low Moor as they were either supplanted by diesels or their steam depot closed down.

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 ...
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.
In the European part of the USSR, almost all steam locomotives were replaced by diesel and electric locomotives in the 1960s; in Siberia and Central Asia, state records verify that L-class 2-10-0 s and LV-class 2-10-2 s were not retired until 1985. Until 1994, Russia had at least 1,000 steam locomotives stored in operable condition in case of ...
A direct-drive 5 MW steam turbine. Electrical power stations use large steam turbines driving electric generators to produce most (about 80%) of the world's electricity. The advent of large steam turbines made central-station electricity generation practical, since reciprocating steam engines of large rating became very bulky, and operated at ...
Edward Pritchard was born in Caulfield, Melbourne, Australia on 28 August 1930. [1] Pritchard was 12 years old when his father explained the operation of a steam engine to him, [2] and by 14 he had worked out an infinitely variable gear device for his bicycle.
A claimant to the title of the first ship to make the transatlantic trip substantially under steam power is the British-built Dutch-owned Curaçao, a wooden 438-ton vessel built in Dover and powered by two 50 hp engines, which crossed from Hellevoetsluis, near Rotterdam on 26 April 1827 to Paramaribo, Surinam on 24 May, spending 11 days under ...
