• Non-condensing firetube boilers are available for low- or high-pressure steam, or for hot water applications. Typically, a firetube boiler uses a cylindrical vessel, with the flame in the furnace and the combustion gases inside the tubes. The furnace and tubes are contained within this vessel, which also houses the water and steam.


    Firetube boilers are available in either dryback or wetback design. In the dryback boiler, a large and swingable refractory-lined rear door, integral with the vessel, is used to direct the combustion gases from the furnace to the multiple tube banks. The wetback boiler design has a water-cooled turnaround chamber that is used to direct the flue gases from the furnace to the tube banks. The wetback design requires less refractory maintenance; however, internal pressure vessel maintenance, such as cleaning and tube removal, is more difficult.
