Large-Scale Utility Power
Shortly after our establishment in 1867, Babcock & Wilcox designed the world's first installed utility boiler. B&W boilers now provide more than 300,000 MW of generating capacity in approximately 60 countries.
In 1957 when B&W built the world's first commercially operated supercritical boiler, our designs were instrumental in the advancement of power generation efficiency. Since then, we've designed and constructed the first U.S. ultra-supercritical power plant using technology representing the most advanced steam cycle conditions commercially available today.
Pulp & Paper Process Recovery
Many decades ago, B&W placed into service the first “black liquor” recovery boiler in the U.S. which used a by-product of the pulping process as fuel. With one of the largest installed base in the world of more than 350 recovery boilers, B&W is committed to the pulp and paper industry by helping today's energy-intensive mills.
When we developed our first waste-to-energy plant in 1930, it revolutionized waste disposal techniques. Over the years. B&W and Babcock & Wilcox Volund waste-to-energy, biomass and multi-fuel technologies have been incorporated in more than 500 production lines in more than 30 countries.
Designed for pulverized coal, B&W's advanced once-through ultra-supercritical boilers are usually applied to systems with a capacity of 400 MW or more. These clean and efficient boilers usually operate at throttle pressures of 3500 psi (24.1 MPa) or more and steam temperatures in the 1100F (595C) range.
B&W's radiant boiler designs accommodate pulverized coal, including difficult-to-burn coals, natural gas and/or oil and combustible byproduct gases. Subcritical pressures range usually 1800 to 2600 psi (12.4 to 17.9 MPa) and superheater and reheater outlet temperatures as required, usually in the range of 1000 to 1050 F (538 to 566C).
With subcritical and supercritical steam pressures, temperatures and capacities, our top-supported, one- or two-drum designs use challenging fuels in a circulating bed of inert particles to control combustion and emissions. The CFB boiler is ideal for high sulfur and high ash fuels and various waste fuels, wood, biomass, gob and culm.
B&W is a leading supplier of water-tube FM and high capacity FM package boilers for start-up and auxiliary power. Units are shop-assembled or modularized with bottom-supported designs for oil, natural gas and other gaseous and liquid fuels. Capacities usually range from 10,000 lb/h (1.3 kg/s) to 600,000 lb/h (25.2 kg/s), depending on type and design features.
B&W integrates steam generation systems for both mass burning of MSW and utilizing refuse-derived fuel. The maximum recovery of resources is a top priority in both designs. Our flexible boiler designs accommodate various capacities, fuel compositions and steam requirements and advanced combustion technologies destroy dioxins and furans, minimize formation of NOx and CO, and minimize unburned carbon.
From biomass combustion to gasification, B&W and B&W Vølund offer a wide variety of solutions for a wide spectrum of biomass fuels, including: wood chips, pellets, saw dust, wheat straw, barley, rice straw, bark and biogas. Biomass maintains a closed carbon cycle (CO2 neutral), which significantly reduces environmental impact.
An effective multi-fuel facility requires appropriate feeder systems for different fuels, appropriate grate technology (often vibrating), and an optimal mixing of flue gases. Our multi-fuel technology is the result of decades of experience with various renewable energy fuels.
B&W's chemical and heat recovery boilers for the pulp and paper industry range from a pulp mill liquor processing capacity to 10,000,000 lb/day (4500 t/day) dry solids at steam pressures up to 1850 psi (12.6 MPa) with the PR design and to 2600 psi (17.9 MPa) with the reheat design.
Our circulating fluidized-bed (CFB) boiler features a top-supported, one- or two-drum design ideal for burning challenging fuels, including high sulfur and high ash fuels and various waste fuels, wood, biomass, gob and culm. Capacity, steam pressure and temperature ranges with subcritical and supercritical applications.
We understand the demand for custom boiler designs and integrated auxiliary equipment for each and every unique application. Steam generating systems like our Towerpak® and Stirling® boilers and other solid and multi-fuel solutions provide the flexibility required for wood, biomass, stoker coal and other industrial applications.
From mid-range capacity PFI/PFT boilers to TSSG designs originally developed to address the need for large modular boilers capable of using lower quality feedwater in the Canadian oil sands region, B&W has a wealth of experience providing industrial boilers ideal for a broad range of applications, and gas and liquid fuels.
