The Lancashire boiler is similar to the Cornish, but has two large flues containing the fires. It was the invention of William Fairbairn in 1844, from a theoretical consideration of the thermodynamics of more efficient boilers that led him to increase the furnace grate area relative to the volume of water.

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 ...
Like the larger Lancashire boilers, exhaust gases were then led through brick flues around the outside of the boiler. [6] An outwardly similar design had been used earlier, with the elephant boiler of the 1840s. [7] [8] This used three cylindrical shells, with two directly heated [iii] cylinders below a single central steam drum. It pre-dated ...
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.
The only railway use of water-tube boilers in any numbers was the Brotan boiler, invented by Johann Brotan in Austria in 1902, and found in rare examples throughout Europe, although Hungary was a keen user and had around 1,000 of them. Like the Baldwin, it combined a water-tube firebox with a fire-tube barrel.

Steam for the pumping engines and auxiliary engines is raised in five Lancashire boilers, with the first set of boilers being made by Robert Stephenson and co. In normal operation only two out of the five boilers would be in steam with one on hot reserve and the other two having maintenance work. The boilers were on an 8 weekly rotation.
