The steam then either travels directly along and down a steam pipe to the engine unit or may first pass into the wet header of a superheater, the role of the latter being to improve thermal efficiency and eliminate water droplets suspended in the "saturated steam", the state in which it leaves the boiler. On leaving the superheater, the steam ...
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
An impromptu attempt to bring the locomotive to steam in 1970 was reportedly attempted by visiting rail crew from the Flying Scotsman, but was aborted after 20 tons of coal failed to heat the boiler enough to produce steam.

Union Pacific 4014 is a preserved 4884-1 class 4-8-8-4 "Big Boy" type steam locomotive owned and operated by the Union Pacific (UP) as part of its heritage fleet.Built in November 1941 by the American Locomotive Company (ALCO) at its Schenectady Locomotive Works, it was assigned to haul heavy freight trains in the Wasatch mountain range.
In Eritrea, steam locomotives are still used in irregular revenue and commercial service. Due to oil shortages in North Korea, steam engines have started to be brought back into service. In the Tuzla region of Bosnia and Herzegovina, the coal mines still use World War II-era German-built steam locomotives.
The Finnish company Steammotor Finland has developed a small rotary steam engine that runs with 800 kW steam generator. The engines are planned to produce electricity in wood chip fired power plants. According to the company, the steam engine named Quadrum generates 27% efficiency and runs with 180 °C steam at 8 bar pressure, while a ...
A portable engine is a type of self-contained steam engine and boiler combination that may be moved from site to site. Although bearing a strong family resemblance, in both appearance and (stationary) operation, the portable engine is not classed as a traction engine as it is not self-propelled.
Such an engine incorporates a piston acted upon by steam alternately on the two sides, hence doubling its power. The linkage actually used by Watt (also invented by him) in his later rotary beam engines was called the parallel motion linkage, a development of "Watt's linkage", but using the same principle. The piston of the engine is attached ...
