A water tube boiler Choosing The Right Boiler: Watertube vs. Firetube - Boiler https://Jun 13, 2013· Fuel is burned inside the furnace, which heats the water in the steam-generating tubes. The water then rises to the steam drum where saturated steam is drawn from the top of the drum. The watertube boiler has some relative advantages over the firetube boiler design, which are outlined below.
