Steamships
Screw-propelled Steamships
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.
Steamships with screw propeller has a number of advantages and these steamships are better in rough sea since the screw is continually submerged.
Side-wheelers, Steamship with a paddle-wheel at each side of the ship
Some steamships had one steam-engine for each paddle-wheel. Later steamships had the paddle-wheels mounted on the very same shaft. A paddle steamship can carry less cargo since the draught will influence on the paddle-wheels efficiency. If the wheels are too much submerged they will not work at all.
Stern-wheelers, Steamship with a paddle-wheel at the stern
The Mississippi River Stern-wheelers have a steering system that is very different from other ships. On screw propelled steamships, the rudder is behind the propeller. A stern-wheeler has its very large rudder ahead of the paddle-wheel. This makes these steamships more manoeuvrable in astern than ahead going.
Navy steamships
Navy steamships was originally propelled in the same way as the merchant marine steamships, 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 large navy steamships like aircraft carrier.
Steamboats
Steamboats are usually smaller steam-powered boats working on lakes and rivers. To distinguish between a steamboat and a steamship: if the length is 12m or more and the beam is 4m or more then it is a steamship otherwise it is a steamboat.
In this particular site steamboats are boats without separate engine rooms, whether or not it's officially a steamboat.
A steamship usually carry a prefix before its names: SS=Steamship,
PS=Paddle Steamer, TS=Turbine Ship, SL=Steam Launch, RMS=Royal Mail Steamer, MV= diesel Motor-driven Vessels.
Some people claim that the American steamship Savannah was the first steamship to cross the Atlantic Ocean in 1819. The Steamship Savannah 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.
Curaçao a small Dutch mail carrier steamship crossed de Atlantic Ocean several times, mostly under steam power, in 1826-28. That I call steamships voyages.
Reciprocating steam-engines and scotch fire-tube boilers used to propel steamships with paddle wheels, paddle wheelers, and steamships with screw propeller
There are three main types or reciprocating steam-engines used in steamships: compound, triple and quadruple-expansion engines. A few minor steamships are provided with single piston engines.
Steamships with Compound steam-engine
The steam expand in two steps from the boiler pressure to the exhaust pressure using one high-pressure and one low-pressure cylinder.
Compound steam-engines with three cylinders have been used, especially as auxiliary engines to produce electricity onboard the steamships. In that case there were three cylinders with the very same diameter, on high pressure cylinder two low pressure cylinders.
Steamships with Triple-Expansion steam-engine
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.
Steamships with Quadruple-Expansion steam-engine
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.
The steamship Inchmona owned by Hamilton Fraser & steamships 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.
Valve-gear is the equipment used to reverse the steam-engine in steamships. All steamships have a valve-gear although Stephenson named his valve-gear a link-motion.
