@spentacle You people !!!!!

HEY! It's one of those engines used in the Titanic!
-
Imagine one of those in my living room running on compressed air...

@GayBoyRunning Triple expansion = Steam from boiler - Quarter stroke - Input HP cylinder - Quarter stroke - Exhaust to reciever - Quarter stroke - input to IP cylinder - Quarter stroke - Exhaust to reciever - Quarter stroke - Input LP cylinder - quarter stroke - Exhaust to condenser feed pump - and repeat.

@fmanh There is only 2 differences. Fuel economy and mainly "Power to weight Ratio"
-
@francovance1 yes
The center shaft was powered by a single direction low pressure turbine.

This is NOT the most powerful engine. It was the main reciprocating engines of the olympic class vessels rated at 16,000HP. Triple expansion direct acting inverted type engine balanced by the Yarrow Schlick and tweedy system. Total gross weight 600 tonnes, Maximum speed 75RPM. Input pressure 215PSI (from 25 double ended and 4 single ended 3 stage coal fired boilers with drafting flue system.

Kelham Island Museum is well worth a visit.

@francovance1 She, along with Olympic and Britannic, used much larger engines that had 4 cylinders instead of 3. This looks more like 3 separate single cylinder engines linked together.....Each cylinder should be getting larger as the steam pressure drops after passing through. That's gotta be really inefficient.
If you people would do the slightest bit of research before posting, you would find that this is a rolling mill engine made for high power and instant reversing. It is SIMPLE expansion using the steam once in each cylinder, which are the same bore. Kempton 6 is made for high efficiency and continuous running and is TRIPLE expansion. The steam passes through each cylinder in turn and they are different bore as the pressure drops. see simtdotcodotuk and kemptonsteamdotorg

@GeneralKenobiSIYE The ship engines you are referring to are TRIPLE EXPANSION but the largest cylinder is split into 2 smaller ones. They are intended to run for very long periods at high efficiency. The River Don engine is built for maximum power for a very short period, just enough to run the steel through the mills, when it has to reverse immediately. Different tools for different jobs.
