Obsolete class of water-tube boilers widely used on ships
Yarrow boiler, with the flue and outer casing removed
Yarrow boilers are an important class of high-pressure water-tube boilers. They were developed by
Yarrow & Co. (London), Shipbuilders and Engineers and were widely used on ships, particularly warships.
The Yarrow boiler design is characteristic of the three-drum boiler: two banks of straight water-tubes are arranged in a triangular row with a single furnace between them. A single steam drum is mounted at the top between them, with smaller water drums at the base of each bank. Circulation, both upwards and downwards, occurs within this same tube bank. The Yarrow's distinctive features were the use of straight tubes and also circulation in both directions taking place within the tube bank, rather than using external downcomers.[1][2][3]
