Most steam propulsion systems use a boiler to produce steam. The boiler burns fuel and then transfers the heat produced into circulating boiler water. [ 2 ] Once the water is heated sufficiently it vaporizes into steam and can be used to power a steam engine that produces the mechanical energy that propels the ship.
A steam turbine ship can be either direct propulsion (the turbines, equipped with a reduction gear, rotate directly the propellers), or turboelectric (the turbines rotate electric generators, which in turn feed electric motors operating the propellers). [36]
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II .
Steam propulsion progressed considerably over the rest of the 19th century. Notable developments include the steam surface condenser , which eliminated the use of sea water in the ship's boilers. This, along with improvements in boiler technology, permitted higher steam pressures, and thus the use of higher efficiency multiple expansion ...
The first small vessel that can be considered a steam warship was the Demologos, which was launched in 1815 for the United States Navy. [1] From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs HMS Comet and HMS Monkey, and by the 1830s the navies of America, Russia and France were experimenting with steam-powered warships.

The term steamboat is used to refer to small steam-powered vessels working on lakes, ... The most efficient steam engine used for marine propulsion is the steam ...
The North River Steamboat or North River, colloquially known as the Clermont, is widely regarded as the world's first vessel to demonstrate the viability of using steam propulsion for commercial water transportation. [2]
A screw steamer or screw steamship (abbreviated "SS") is an old term for a steamship or steamboat powered by a steam engine, using one or more propellers (also known as screws) to propel it through the water. Such a ship was also known as an "iron screw steam ship".
