A watertube boiler is a type of boiler in which water circulates through tubes that are heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum.
