Used Package Steam Boilers

Package steam boilers are factory-assembled units that generate steam for process heating, sterilization, and facility operations. These self-contained systems include the pressure vessel, burner, controls, and safety devices mounted on a single skid, simplifying installation compared to field-erected boiler systems.

Federal Equipment Company stocks used package steam boilers in fire-tube and water-tube configurations. Available units include gas-fired designs with capacities suitable for small to mid-size industrial steam requirements.

Package steam boilers generate pressurized steam by heating water in a closed pressure vessel. The term “package” refers to the factory-assembled design in which all components—burner, controls, feedwater system, and safety devices—ship as a complete unit ready for connection to fuel, water, and steam distribution lines.

Two primary configurations are available. Fire-tube boilers pass hot combustion gases through tubes surrounded by water, offering compact footprints and rapid steam generation for fluctuating loads. Water-tube boilers circulate water through tubes surrounded by combustion gases, providing higher steam pressures and capacities for demanding applications. Both designs are available with natural gas, propane, or dual-fuel burners.

Key components include the pressure vessel (rated and stamped per ASME code), burner assembly with combustion controls, feedwater pumps and level controls, safety valves, and flame safeguard systems. Modern units feature microprocessor-based controls with modulating burners that adjust firing rates to match steam demand, improving fuel efficiency during partial-load operation.

Federal Equipment Company can provide inspection, hydrostatic testing, and burner tuning services to verify equipment condition and performance. Our team can help match available inventory to your steam pressure, capacity, and fuel requirements.

Why Buy Used Package Steam Boilers

Used package steam boilers offer substantial cost savings compared to new equipment, often 40% to 60% depending on age, capacity, and condition. Because these systems are built to ASME pressure vessel codes and designed for decades of service, properly maintained units retain significant operational value.

New boiler procurement typically involves extended manufacturing lead times, plus additional time for permitting, installation, and commissioning. Used equipment from Federal Equipment Company is available for faster delivery, helping facilities restore steam capacity or add redundancy without lengthy project timelines.

Federal Equipment Company can provide hydrostatic pressure testing, burner inspection, and controls verification to confirm equipment condition before delivery. Our team can also assist with documentation for jurisdictional registration and insurance requirements.
