Multi-tube boilers

A significant step forward came in France in 1828 when Marc Ssguin devised a two-pass boiler of which the second pass was formed by a bundle of multiple tubes. A similar design with natural induction used for marine purposes was the popular “Scotch” marine boiler. Prior to the Rainhill trials of 1829 Henry Booth, treasurer of the Liverpool and Meanchester Railway suggested to George Stephenson, a scheme for a multi-tube one-pass horizontal boiler made up of two units: a Firebox surrounded by water spaces and a boiler barrel consisting of two telescopic rings inside which were mounted 25 copper tubes; the tube bundle occupied much of the water space in the barrel and vastly improved heat transfer.

Old George immediately communicated the scheme to his son Robert and this was the boiler used on Stephenson's Rocket, outright winner of the trial. The design was and formed the basis for all subsequent Stephensonian-built locomotives, being immediately taken up by other constructors; this pattern of fire-tube boiler has been built ever since

In this kind of boiler, combustion of heat, as well as gases, flows through the pipe enclosed by water. These boilers may be high-pressure or low-pressure boilers. The measurement of these boilers can be done always with their external diameter.
