A package boiler or packaged boiler is a modern form of steam boiler. They are factory-made to a range of standard designs, according to the size and evaporative capacity required. They are used as both hydronic boilers for heating and as steam generators for small power purposes.
Every set of tubes that the flue gas travels through is considered a âpassâ. Boilers designed for three-passes have the stack at the rear, and boilers designed for four-passes have the stack at the front. A boiler with more passes has a higher heat extraction rate and is more efficient then one with less passes. Watertube boilers are safer by design and generally can operate many years longer than firetube boilers.
