Smithies boiler: A development of the pot boiler with added watertubes, used for model steam locomotives. [52] The boiler was invented by F. Smithies in 1900 and developed by Greenly. It consists of a cylindrical water drum hidden inside a larger drum that forms the visible part of the model.
The history of the Vaillant Group dates back to 1874, when Johann Vaillant set up a master fitter's business. In 1894 Johann Vaillant patented a new "closed-system" gas-fired bathroom boiler. [3] This was the first device that made it possible to heat water hygienically, without contaminating it with combustion gases.
Many models sold in the UK have introduced a small heat store within the combination boiler to address this issue. This "keep hot" facility considerably improves the standard of hot water service, which some people otherwise find unacceptably poor with a combination boiler, but it uses considerably more fuel especially in summer.

In the flued boiler, any sediment fell past the furnace flue and settled out at the bottom of the boiler shell, where it had less effect. [5] In model engineering, the Cornish boiler, particularly when fitted with Galloway tubes (see Lancashire Boiler, below), is an excellent choice for gas-fired boilers and model steam boats. It is simple to ...
erosion of a boiler's plates from the internal water space, particularly where there is a step inside the shell. This was a problem for early boilers made from lapped plates rather than butted plates, and gave rise to many boiler explosions. In later years it was a problem for the non-circular water drums of Yarrow boilers. Handhole

Cochran boiler. A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. It is characterised by having many narrow fire-tubes, running horizontally. Boilers like this have been widely used on ships as either auxiliary or donkey boilers.
