Some of the flexible-boiler engines lingered on the roster for 18-19 years, with the last ones going to scrap in 1929. How many of those years they were actually out pulling trains, I can't say. The 3322 at least was still servicable in 1920 when it was tested against a new 3800-class Liming (and lost out in nearly every category).Get Price
Aug 10, 2017 · Tek Tube is a leading manufacturer of welded boiler and heat exchanger tubes located in Tulsa Oklahoma. I recently did some design consulting on a stationary boiler project where XID tubes were specified. I did a little research on these and wonder if they might not make a good replacement for locomotive boiler tubes. Technical data is Get Price

Oct 14, 2012 · There was an article some years ago in Trains about the "prairie Mallets". In addition to the Liming-2 freight Mallets, some of which had ordinary Mallet boilers, AT&SF also had some Liming-2 passenger Mallets without the flexible boiler. Here's from E.P Alexander's classic "American Locomotives 1900-1950" (Bonanza, New York, 1950)Get Price
Apr 19, 2008 · This locomotive was built in 1910-11, and transferred to the Ceinture in 1921. Note that this version has a cylindrical tank on top of the boiler that is not present on the Nord locomotives. It was presumably either a feedwater heater or a brake reservoir- which is currently unknown. Image courtesy of Bruno Bretelle.Get Price
The boiler was of the locomotive Belpaire type, and provided 1,996.5 sq. ft. of heating surface. The grate area was 35.95 sq. ft. The boiler pressure carried was about 200 lbs. to the sq. in. The engine was compound with six cranks set in a form that was reported to give perfect equilibrium.Get Price

What is Steam Boiler? A steam boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam …Get Price

Not that I'm suggesting that this would work in reality - the Triplexes that were actually built were terrible and barely had enough steam to operate, and the Santa Fe mallet classes 1158 and 3300 that used flexible boilers were pretty miserable too.Get Price
