RMweb Premium Dave Hunt Posted April 18, 2021 RMweb Premium Share Posted April 18, 2021 I was once talking to a non-railway orientated friend and mentioned compound expansion, saying that it was a subject of some controversy among enthusiasts and briefly describing the different methods tried. He commented that they were all just double expansion and asked why no-one had tried triple expansion. I showed him a photograph of a Webb Compound with the low pressure cylinder cover visible. "Ah, " he said, " Now I see." Dave 7 1 Link to post Share on other sites More sharing options...

As powers increased this became an efficiency issue, so later large engines had four cylinders, but were triple expansion, with two low pressure cylinders. Getting the steam in and out is a problem with such large volumes - valves have to be huge, and are restrictive and also take a lot of power to actually move. In my field of large slow speed diesel engines the same issues applied, with cylinder bores peaking at about 1050mm, then easing back into the 900's as the diminishing returns came into play. The improvements in power now are to to massively improved injection systems and very high turbocharging boost pressures. The specific outputs have doubled since my 'days' in the 70/80's. 7 Link to post Share on other sites More sharing options...

Anyone know who in the RAF you speak to about them attending a deceased comrades funeral." The RAF Benevolent Association. My late FiL was ex RAF, a merlin engine fitter in 111 Squadron in WW2 and stayed on post-war with a commission. A young pilot from 111 attended his funeral. Subsequently his ashes were dropped from the BBMF Lancaster somewhere in the Midlands. "There's always a coffin, even if its empty. Pall bearers have to have something to carry!" A sad story from Dad's days with Combined Ops/Commando training in Scotland; a young officer stepped on a live mine. At the funeral his wife wanted to see him in the coffin. She had to be firmly dissuaded ("The lid is screwed down ma'am and we can't undo it now") as it contained one uniform button and a number of bricks to give it some weight.

Florence Locomotive Works Posted April 19, 2021 Share Posted April 19, 2021 (edited) On 17/04/2021 at 15:53, Tony_S said: I hope it was a reduced scale diagram. When I visited USS Texas the final cylinder of the triple expansion engine was enormous. The interesting thing about the Texas' engines is that they have two low pressure cylinders, with the high and intermediate pressure cylinders sandwiched in the middle. This is the (IRC) same design as those of the Olympic class ocean liners. This design is also used when you want a horizontal pumping engine that doesn't need a whopping great big condenser, or if you simply have too high a steam volume for a single low pressure cylinder. But this factor is often regulated by whether or not the final low pressure cylinder works on a vacuum, for example a lot of Allis Chalmers triple expansion pumping engines have low pressure cylinders that work at approximately -2 psi, and those only have one LP cylinder.

Florence Locomotive Works Posted April 19, 2021 Share Posted April 19, 2021 (edited) Evening all, The first karting drive of that year was had yesterday, and went surprisingly well. I may be racing next weekend, or I may wait another week before starting that. Yesterday the leaks on the engine were hopefully fixed. Dad has also found some suitable tubing for the water tank, now a base needs finding and cutting to size. Tomorrow I will be taking the pre ACT one of the three major exams one has in high school. That will last from about 8:00 until around 11:45, and after that, I'm done for the day. So hopefully I can steam test the engine again or something.

RMweb Gold Happy Hippo Posted April 19, 2021 Author RMweb Gold Share Posted April 19, 2021 Our next door neighbours are having a mancave/bolt hole built at the bottom of their garden. It's quite a bit larger than we (and they) expected. at 10 x 6 (metres) However in one of my many conversations we have on the part of our driveway which is shared, I dropped into the conversation the question of being allowed to put up one of my railways inside the mighty structure on occasions 'for testing purposes' explaining the problems we have when 'testing' during the colder months. Railway squatting rights have been achieved, before the place is even built, so an excellent result there! 12 1 3 Link to post Share on other sites More sharing options...
