Yarrow boiler - Wikipedia

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.
