An external furnace package boiler operates by burning the fuel in an externally located furnace chamber that is distinct from the boiler shell, generating hot flue gases which pass through tubes to transfer heat to water or steam. The hot gases generate various passes or tube circuits (based on design) before the exhaust is vented out, thus heating the water/steam contained inside the boiler shell. These are blended with sophisticated fuel supply, flue gas recirculation, and control in modern systems to get them cleaner and more efficient.
