Where were the engines located in the Titanic?

Answer 1

She was steam-powered. Titanic had two 4-cylinder steam reciprocating (piston)engines which were each two stories tall and drove the two wing screws (propellers). They each had a high-pressure cylinder, an intermediate-pressure cylinder, and two low-pressure cylinders. The steam ejected from the low-pressure cylinders of these two engines fed the low-pressure Parsons steam turbine which drove the center screw. The turbine was there to wring the last ounce of drive from the steam before it was sent off to the main condensers. The steam for the engines was provided by 29 coal-fired boilers; 24 of these were double-ended (meaning they had 3 furnaces on each side) and the remaining 5 were single-ended. The normal operating pressure for the boilers was around 215 psi.

This engine layout is called a "triple expansion." Steam from the boilers entered the high-pressure cylinders of each reciprocating engine via the intake headers. From there, the steam went into the intermediate and then the low pressure cylinders. From the low-pressure cylinders, some steam was fed to the Parsons turbine and some was carried out via the exhaust headers. From here, the steam was sent off to the main condensers where it was condensed back into water and fed back to the boilers to repeat the cycle. While this was going on, valve lifters at the top of the cylinders were opened and closed by what's called an "eccentric link" to feed steam into the cylinders and eject it. Steam forced the pistons up and down, moving the connecting rods which turned the crankshafts, flywheels, and propeller shafts--similar to the way an automobile engine works. Titanic's engines produced around 45,000 horsepower altogether.

The steam turbine is basically a series of fans arranged in a row. These fans are turned by the action of steam being forced through the blades, which provide the torque to turn the propeller shaft. As with the reciprocating engines, reduction gear was used to make the ship's screws turn fewer revolutions than the engines.

Answer 2

Boilers provided steam to two different types of engines. The two outer propellors were turned by a triple expansion steam engine. ( 3 different pistons are pushed by expanding steam) The center prop was turned by a steam turgine engine.

Answer 3

Yes. Steam engines drove her wing propellers and a steam turbine drove her central propeller. The turbine engine was not reversible although the steam engines were.

Answer 4

No, the ship stopped it engines shortly after hitting the iceberg.

However there was still fire in the boilers up until the water reached them.

Answer 5

it was drive by external combustion engine.
