In a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons.
