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 boils 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

Benson Boiler is a high pressure, drumless, supercritical, water tube steam boiler with forced circulation. This boiler was invented in the year 1922 by Mark Benson. This boiler is a supercritical boiler in which the feed water is compressed to a supercritical pressure and this prevents the formation of bubbles in the water tube surface.

Industrial water tube boilers have a much more efficient design that saves both space and energy. that flows throughout the boiler. With the water tube design, the water is surrounded by heated gases rather than the other way around. The hot gas moves from the firebox into the boiler's main chamber.
