Inspiration for the builder: A list of other vertical boilers
Posted: Sun Jun 21, 2020 10:07 am
Hello,
I've stumbled upon an article about steam boilers for locomotives, which might not sound too fitting, but the article had a chapter about vertical steam boilers, of whose designs many look like they can work in a steam boat as well. And the design of some of them is really interesting.
I tried to find an english version of the site, but it isn't all that important, because the pictures speak for themselves after all. Here is the source:

I used the names from the descriptions of the pictures, but they aren't necessarily the official names. But a researcher might find it useful to find background information about them.
Fig. 1 shows a boiler from Léon Serpollet, a pioneering inventor. The tiny pressure vessel on the right side of the boiler probably is the steam dryer.
Fig. 2 shows a boiler from De Dion-Boulton. Note the absence of plugs to access the many radial water tubes for maintenance. Long stay bolts hold the boiler together instead.
Fig. 3 The schematics of this boiler named Stolz immediately show a resemblance of the Belleville boiler, but it avoids the heavy tube plates.
Fig. 4 This boiler used by Komarek makes use of different "smartifications". The entire fire box consists of a corrugated tube and a number of tubes hang inside the fire box.
Fig. 5 The Kittel boiler is very straight forward. Note the widening of the boiler at the height of the design water level to counteract priming.
Fig. 6 This boiler is from the Société Valentin Purrey for its steam railcars. It also looks like a deviation of the Belleville boiler, replacing the tube plates with bent tubes and thus less connections.
Fig. 7 The Great Western boiler is also a straight forward vertical fire tube boiler. Note again the use of a bigger water surface to counteract priming.
Fig. 8 I've seen this boiler in a model steam handbook but thought its shape might have been created as an adaptation to the model scale. But it did exist as a big scale version after all. This boiler from the Taff Vale Railroad looks like an inversion of a double-sided scotch marine boiler with the firebox in the center. Technically, it is a combination of a vertical and a horizontal boiler merged to a "T". A similar boiler was used by the Yorkshire Patent Steam Wagon Co. .
Fig. 9 This boiler from the danish mastermind Rowan was part of a railcar built in Great Britain and to be used in Australia. The resemblance to the Sentinel boiler is very visible, although it is bottom-fired and possesses a simpler top, lacking economizer tubes and steam dryer of a Sentinel boiler.
