Yarrow boiler

A Yarrow boiler has been developed by the British shipyard Yarrow Shipbuilders steam boiler design, which was used primarily to turbine-powered warships.

Construction

It is a water -tube boiler with three drums in a delta form ( Δ ) with two small lower drums that were arranged on both sides of the combustion chamber and were connected by straight pipes with the central upper drum. The downspouts were outside the front side of the furnace. The straight tubes were easy to clean, but the connection was more difficult to produce to the upper drum due to the varying entry angle.

Use

The Yarrow boiler is characterized by its compact and rugged design and was therefore well suited for narrow engine rooms of ships. It was combined with both steam engines and later with steam turbines.

The boiler was very successful and was widely used, especially in British, produced by Yarrow own ships, but also at other shipyards and other nations that copied the design. In the Royal Navy, he was on the HMS Hornet (1893 ) test as used in the construction of the torpedo boat destroyer Havock class for the first time in 1893 and subsequently introduced. A further development from the period between the world wars was known as the Admiralty boiler three -drum, and was first built in the destroyers of the A-Class in 1929.

Chance of Yarrow boilers were also in the Second World War - mounted on a railroad trestle - used as a steam generator for mobile power plants for the military.
