Package Boilers

Water-tube Package and Industrial Boilers
More than 5,000 units and 150 years of experience

B&W’s line of industrial package boilers represents more than 150 years of ingenuity and experience, providing dependable performance for a wide range of industries and applications.

Over the years, our industrial boiler configurations have been known by various model names, including FM, HCFM, PFM, PFI, PFT, TSSG^® and others — D-type or O-type, single-drum or multi-drum. The unique designs offered by these various models provide our customers with flexible options and features to meet any steam generation demand.

Design Features and Benefits of our Water-tube Package Boilers

Furnace wall water cooling – eliminates refractory and related maintenance

Gas-tight setting membrane – inhibits dew-point sulfur corrosion and outages caused by gas leaks

Rugged steel-based frame – supports boiler and allows jacking and skidding

Outer lagging – galvanized, weather-tight for outdoor installations

Drum internals – ensure positive circulation, low moisture, high steam purity

Larger tube diameter (2.5 in. [6.35 cm] tubes spaced 1 in. [2.54 cm] apart) – contributes to a faster load response and helps prevent membrane thermal cracking

Grooved tube seats – protect against leaks during transportation and throughout operation

Solid membraned division wall – prohibits furnace gases from bypassing generating tubes

Water wash troughs and drains – facilitates offline water-washing

Inverted loop, fully drainable superheaters – saves time during startup while minimizing the chances of over-heat during the pressure-raising stage.

Sootblowers – for effective cleaning of the superheater, generating bank and other heat transfer surfaces

B&W Innovation

MultiCirc (patent-pending)

Our multi-circulation systems accommodate lower-quality feedwater and maximize thermal efficiency while maintaining reliability by minimizing boiler tube internal scaling.

Connection Ready

The boiler and auxiliary equipment modules, depending on size, can be shop mounted to skids where they are pre-wired and piped to accelerate transportation and reduce field installation times.

Elevated Drum

Our elevated-drum design is used for drum retention times of 5 minutes or more from normal water level to low water fuel cutout. Additionally, this design is utilized where shipping limitations exist as it allows for a more symmetrical load with the upper steam drum shipped separately from the boiler and installed onsite.

Auxiliary Equipment

• Economizers
• Burners
• Controls
• Forced draft fan and drives
• Flues and ducts
• Stacks
• Deaerators, feedwater pump sets
• Oil pumps
• Heater sets
• Post-combustion emissions control systems
• Code piping
• Balance of plant

Aftermarket Support

B&W’s network of field service engineers can provide services ranging from routine inspections and controls tuning to engineering studies, low emissions conversions or new control systems.

Success Stories

Elevated three-drum unit for IRPC Clean Power Co., Ltd. in Rayong, Thailand

To meet the project’s steam drum retention requirements, we engineered and delivered an elevated three-drum unit for the combined heat and power plant’s use in supplying steam to a neighboring factory.

Single-drum modular units for oil sands project in Alberta, Canada

Challenged to provide a solution for highly reliable steam generation at high pressure with ultra-low NOx emissions, minimized blowdown for zero liquid discharge requirements, multifuel usage, and low field erection and maintenance costs, we supplied eight high-performing modularized single-drum units.

Custom-branded units for U.S. universities

In addition to predefined specifications for operating conditions, our industrial boilers can be delivered featuring designated colors and logos. We recently supplied two U.S. universities with multiple custom-branded units, each capable of providing approximately 80,000 lb/hr (36,300 kg/hr) of saturated steam with a design pressure of 250 psig (1.7 MPa).

Installation of lower drum heating coils on industrial boilers reduces fuel, costs and emissions

Valent BioSciences LLC (VBC) - Iowa, USA

B&W designed and fabricated lower (mud) drum heating coils for two industrial boilers. The coils allow the auxiliary, idle unit to maintain a hot standby condition using steam from the operating boiler.
