Fire Tube - an overview | ScienceDirect Topics

Fire-tube boilers: The hot combustion products flow through tubes submerged within the water contained in these boilers. To increase the contact surface area between the hot gases and the water, two to four passes are used for the tubes. The multipass tubes increase the efficiency of the boiler but require greater fan power.
