B&W Heros Boilers
Heros™ Water-tube Boiler

Heros Boilers

More than 5,000 units and 150 years of experience

B&W's Heros™ water-tube boilers have an established reputation for reliability and proven performance in a variety of industries.

Our water-tube (package) boilers are available in a wide range of capacities, and are continually enhanced by incorporating the latest technological advancements. A full complement of auxiliary components and add-on features are available depending upon your application. In addition, we offer comprehensive installation and support services after the sale.

Heros Boiler

Heros industrial boiler benefits: 

  • Reliable power with low emissions
  • Low auxiliary power requirements
  • Low greenhouse gas footprint
  • Simple operation and low maintenance
  • Operational flexibility – high turndown and fast load ramping

High capacity package boilers

B&W also provides higher capacity package boilers available for both oil and gas firing. These units feature multiple burners for increased capacity. Given the footprint these boilers can be either shop, dock, or field assembled; otherwise units are shipped by barge or ocean vessel. Benefits Include: 

  • Long-term reliability
  • Fast load response
  • Low operating cost
  • Controlled Emissions


Reliability is standard. Everything else can be customized.
Our Heros industrial water tube boilers can be found in utilities, mills, refineries, universities, institutions, mines and other industrial facilities across the globe. They are engineered to meet unique capacity, space, fuel, emissions, transportation, installation and other requirements.

Capability Range

 Capacity  10,000 to 1,200,000 lb/hr (4.5 to 544.2 T/hr)
 Size/Space  Various modular designs for shop and/or field assembly
 Temperature  Saturated to 1005F (540C)
 Design Pressure  250 to 2400 psig (1.7 to 16.5 MPa)
 Fuel Liquid or gaseous fuels such as oil, natural gas, carbon monoxide (CO), blast furnace gas (BFG), coke oven gas (COG), and more
 Emissions and water-side deposition control systems
 Timeline/Budget  Design and construction variances to meet cost,  scheduling requirements

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.

Heros Boiler Connection Ready

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.

Heros Boilers Elevated Drum

Design Features

Furnace wall water cooling
Eliminates refractory and related maintenance

Gas-tight setting membrane
Inhibits dewpoint 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

Clean convection banks, includes bearings, wallbox(es) and tube openings

Solid membrane division wall
Prohibits furnace gases from bypassing generating tubes

Larger tube diameter
Helps to prevent membrane thermal cracking and contributes to a faster load response

Inverted loop, fully drainable superheaters

Water wash troughs and drains

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

Oil Sands Heros Boilers
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.

High-capacity unit for U.S. refinery           

Refinery Hero Boiler
We engineered and supplied a 300,000 lb/hr (136,100 kg/hr) shop-assembled unit, which was shipped by barge and field-installed. The project scope also included all boiler auxiliaries, fans, economizer, valves, instrumentation and installation of all equipment on the boiler island.

Custom-branded units for U.S. universities

Heros Boiler
In addition to predefined specifications for operating conditions, our Heros 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).
