Fire Tube Steam Boiler | Nationwide Boiler - Nationwide

Firetube boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers). Every set of tubes that the flue gas travels through is considered a "pass". Boilers designed for three-passes have the stack at the rear, and boilers designed for four-passes have the stack at the front.
