Firetube boilers are ideal for smaller hot water and steam applications requiring 15-1,500 boiler HP (500-50,000 lb/hr). These units have a typical operating pressure no higher than 300 psig. Firetube and watertube boilers are distinguished from one another by the arrangement of the heat transfer surfaces inside the boiler. For a firetube boiler, water fills the shell of the boiler and the hot gas produced by the burner travels through smaller tubes within the shell, allowing the heat to pass out of the ‘fire tubes’ and into the surrounding water. The gas will typically pass through the water-filled shell one to three times, called passes, depending on the boiler design, before exiting through the stack. The back wall of the boiler can be insulated with refractory (‘dry-wall’) or water-filled to improve efficiency (‘wet-wall’).
Instead of pushing hot exhaust gas through small tubes in a larger water-filled vessel, a watertube boiler passes small tubes filled with water through the combustion chamber. As the system size increases, watertube boilers become more common, particularly for applications where high pressure (>300 psig) is desirable. Watertube boilers can be designed to include superheaters, allowing them to be used for a wide range of applications, from utility scale power generation to chemical production, pulp and paper, and more.
