Early watertube boilers. Early use of the water-tube boiler within the Royal Navy was controversial at times, giving rise to the 'Battle of the Boilers' around 1900. These first boilers, such as the Belleville and Niclausse, were large-tube designs, with simple straight tubes of around 4" diameter, at a shallow angle to the horizontal. These tubes were jointed into cast iron headers and gave ...

Circulatic® Watertube Steam Generators | Vapor Pow

The Circulatic® Watertube Steam Generator is a forced recirculation watertube boiler that uses a drum as a steam separator and a reservoir of water to supply the coils. A recirculating pump draws the water from the drum and forces it through a set of parallel connected coils at the rate of 3 to 4 times the maximum steaming rate.

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes ...

Steam drum - Wikiped

A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.
