Steamships

In that case there were three cylinders with the very same diameter, on high pressure cylinder two low pressure cylinders . </P> <H2>Steamships with Triple-Expansion steam engine</H2> <P> The steam expand in three steps from the boiler pressure to the exhaust pressure using one high-pressure-cylinder, one intermediate-pressure-cylinder and one low-pressure-cylinder. In large steamships the steam engines very large and heavy low-pressure-piston could hardly be lifted by the low pressure steam and it was therefore replaced by two low-pressure-pistons. In that case there were four cylinders, one high- pressure, one intermediate-pressure cylinder and two low-pressure cylinders.</P> <H2>Steamships with Quadruple-Expansion steam engine</H2> <P> The steam expands in four steps from the boiler pressure to the exhaust pressure using one high-pressure cylinder, two different size intermediate-pressure cylinder and one low-pressure cylinder. <BR> The steamship Inchmona owned by Hamilton Fraser & Company had a five-cylinders quadruple-expansion steam engine; one high pressure-cylinder two different sized intermediate-pressure-cylinders and two equal sized low pressure cylinders.</P> <H2>Screw-propelled Steamships</H2> <P>In the end of 1850 the screw propelled steamships become recognized as superior to paddle-wheelers and after that the steamships began to supersede the sailing ships.<BR> The screw propeller has a number of advantages. It is better in rough sea since the screw is continually submerged.</P> <H2>Side-wheelers, Steamship with a paddle-wheel at each side of the ship</H2> <P> Some paddle wheelers had one steam engine for each paddle wheel. Later paddle ships had the paddle wheels mounted on the very same shaft and hence the paddle wheels could not be used to steer the ship. A paddle steamer can carry less cargo since the draught will influence on the paddle wheels efficiency. If the paddle wheels are too much submerged they will not work at all.</P> <H2>Stern-wheelers, Steamship with a paddle-wheel at the stearn.</H2> <P>The Mississippi River Stern-wheelers have a steering system that is very different from other ships. On screw propelled ships, the rudder is behind the propeller. A stern-wheeler has its very large rudder in front of the paddle wheel. This makes these paddlewheelers more maneuverable in reverse than forward going.</P> <P> </P> <H2>Navy steamships</H2> <P> Navy ships was originally propelled in the same way as the merchant marine ships, but son they become provided with water tube boilers with higher steam pressure and nowadays they are equipped with nuclear reactors for steam generation. Especially the larger ones like aircraft carrier.</P> <H2>Steamboats</H2> <P>Steamboats are usually smaller steam-powered boats working on lakes and rivers. In this particular site steamboats are steam propelled boats without separate engine rooms. </P> <H3> A steamship usually carry a prefix before its names: SS=Steamship, PS=Paddle Steamer, TS=Turbine Ship, SL=Steam Launch, RMS=Royal Mail Steamer </H3> <P>Some people claim that the American ship <B>Savannah</B> was the first steamship to cross the Atlantic Ocean in 1819. <B>Savannah</B> was a sailing ship fitted with steam engines and side- wheels. During the twenty-nine days voyage they used the steam engine less than four days. I don't consider that a steamship voyage.<BR> <B>Curaçao</B> a small Dutch mail carrier crossed de Atlantic Ocean several times, mostly under steam power, in 1826-28 . </P> <H3> <A HREF="http://www.steamesteem.com">Steam esteem in a computerized world</A><BR> <A HREF="steamships/index.html" TARGET="MAIN">Swedish steamships</A><BR> <A HREF="steamboats/index.html" TARGET="MAIN">Swedish steamboats</A><BR> <A HREF="steamship/index.html" TARGET="MAIN">European Steamships</A><BR> <A HREF="steamboat/index.html" TARGET="MAIN">European steamboats</A><BR> <A HREF="fartyg/angfartyg.html">Steamships</A>   Swedish Steamships<BR> <A HREF="fartyg/angpannor.html">Steam boilers</A>   Fire tube boilers and water tube boilers<BR> <A HREF="fartyg/angmaskiner.html">Steam engines</A>   Reciprocating steam engines<BR> <A HREF="fartyg/a-jack.html">Jack</A>   A small flag at the bow of a ship </H3> <H3><B>Swedish Steamships</B><BR> <A HREF="steamships/blidosund.html" TARGET="MAIN" TITLE="Swedish Steamship Blidösund from Norrtälje">Swedish Steamship Blidösund from Norrtälje</A> Two cylinder compound expansion engine with Flodman's reversing link motion<BR> <A HREF="steamships/bohuslan.html" TARGET="MAIN" TITLE="Swedish Steamship Bohuslän from Gothenburg">Swedish Steamship Bohuslän from Gothenburg</A> Three cylinder triple expansion engine with Stephenson's reversing link motion<BR> <A HREF="steamships/bore.html" TARGET="MAIN" TITLE="Swedish Steamship Bore from Västerås">Swedish Steamship Bore from Västerås</A> Icebreaker<BR> <A HREF="steamships/boxholm-2.html" TARGET="MAIN" TITLE="Swedish Steamship Boxholm II from Boxholm">Swedish Steamship Boxholm II from Boxholm</A> The ship was delivered in three parts and assembled on the beach of the lake Sommen<BR> <A HREF="steamships/basinge.html" TARGET="MAIN" TITLE="Swedish Steamship Bäsinge from Borlänge">S/S Bäsinge from Borlänge</A> Two cylinder compound expansion engine with Stephenson's reversing link motion<BR> <A HREF="steamships/djurgarden-3.html" TARGET="MAIN" TITLE="Steam ferry Djurgården 3 from Stockholm">Steam ferry Djurgården 3 from Stockholm</A> Steam ferry<BR> <A HREF="steamships/domnarfvet.html" TARGET="MAIN" TITLE="Swedish Steamship Domnarfvet from Tomnäs">Domnarfvet from Tomnäs</A> engines manoeuvring levers on the navigation bridge<BR> <A HREF="steamships/drottningholm.html" TARGET="MAIN" TITLE="Swedish Steamship Drottningholm from Stockholm">Drottningholm from Stockholm</A> <BR> <A HREF="steamships/ejdern.html" TARGET="MAIN" TITLE="Swedish Steamship Ejdern from Södertälje">S/S Ejdern from Södertälje</A> nowadays the museum society "Ångfartyget Ejdern" owns and runs her<BR> <A HREF="steamships/engelbrekt.html" TARGET="MAIN" TITLE="Swedish Steamship Engebrekt from Leksand">Engebrekt from Leksand</A> Scotch fire tube boiler with one furnace<BR> <A HREF="steamships/eric-nordevall.html" TARGET="MAIN" TITLE="Swedish Paddle steamer Eric Nordevall II from Forsvik">Swedish Paddle steamer Eric Nordevall II from Forsvik</A> A replica of the paddle steamer Eric Nordevall built in 1836 and foundered in 1856<BR> <A HREF="steamships/flottisten.html" TARGET="MAIN" TITLE="Swedish Steamship Flottisten from Rättvik">Flottisten from Rättvik</A> Built in 1890 at Hernösands mek. verkst.
