Yarrow was also a builder of boilers, and a type of water-tube boiler developed by the company was known as the "Yarrow type boiler". 1865/6 Alfred Yarrow established the partnership of Yarrow and Hedley at Folly Wall, Poplar on the Isle of Dogs to build steam river launches.
Yarrow marine boilers were widely used in the navy of many countries. Later Yarrow boilers had bended tubes to improve the elasticity of the boiler construction. Small Yarrow steam boilers were used in navy launches. These longboats were used to transport passengers and luggage to the navy ships.
Generally we use the water tube boiler in order to generate the super heated steam like on steam ships etc. the pressure generated on water tubes is always higher the smoke type of boilers. The best example of this type of boiler is the cooker that we use in our home.
Photo #1 shows a 3-drum Yarrow semi over-discharge water-tube boiler (identical to the one in my steamboat). It is made of copper and it has 39 sq.ft. of heating surface. The mud drums are 3in. dia. and the steam drum is 6in. dia. The downcomers are 2in. dia. and the four rows of water tubes are 1/2in. o.d.
It is a horizontal type of boiler. Yarrow. Main article: Yarrow boiler. End-view of a Yarrow boiler. Named after its designers, the then Poplar-based Yarrow Shipbuilders, this type of three-drum boiler has three drums in a delta formation connected by watertubes. The drums are linked by straight watertubes, allowing easy tube-cleaning.
'''Boiler'''- An enclosed vessel in which water is heated and circulated, either as hot water or as steam, for heating or power. A container, such as a kettle, is used for boiling liquids. In our context, a boiler is "a piece of heating equipment that is used to heat water for use in a hot water-based heating system."
OverviewYarrow's water-tube boiler. Alfred Yarrow developed his boiler as a response to others that had already developed water-tube boilers. This was a long process based on theoretical experiment rather than evolution of practical boilers. Work began in 1877 and the first commercial boiler was not supplied until 10 years later, a torpedo boat of 1887

Jul 15, 2013· Yarrow type boiler, Bernhard As I have already stated that with the sight glass fitted to the top drum and the bottom drum there could be turbulence when the boiler is fired and the water level will not be steady in the glass.

The image depicts a boiler drum possibly for Yarrow type boiler mounted on petrol driven motor truck for transport.
Apr 29, 2013· Yarrow boiler sight glass. Bernhard, This is where I agree with Brooks, you will have to be careful when steaming the boiler, as you have tubes coming from the bottom mud drums and bending at 90deg going into the top drum you will have a difference in expansion of the tubes directly in contact with the burner which will force the bottom drums
Yarrow was also a builder of boilers, and a type of water-tube boiler developed and patented by the company was known as the "Yarrow boiler", first used in a torpedo boat in 1887 and later used for a number of applications, from the propulsion plant of RMS Queen Mary to the LNER Class W1 locomotive.
One of the best known forms of water tube boiler is the Yarrow boiler. These particular boilers were made for the Southern Railway Company’s cross-Channel steamers. The two boilers at the left hand, which are only partly erected, show the principles of construction. Three steel drums are arranged at the corners of a triangle, the two bottom drums being connected to the top one by a number of
Steam power plant consisting of (1) Single cylinder double acting steam engine 2 hp, cylinder dia 2"xstroke 3", complete with hand lubricating pump for cylinder lubrication, and 10" pulley (2) Water tube Yarrow type boiler suitable for biomass firing with 18 sq ft heating surface including economizer and superheater,water feed pump, test
The whole thing was covered with a big metal box-like cover with a chimney on the top. Sometimes you see pictures of old ships where it looks like the chimney comes out the top of a huge black house-shaped structure: this is likely this type of boiler. Interestingly there was a rail (sorry Mr. Mamod) locomotive built with a Yarrow boiler, too:
