Power Boilers
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.
Renewable Energy Boilers
When we developed our first waste-to-energy plant in 1930, it revolutionized waste disposal techniques.
Over the years, our waste-to-energy, biomass and multi-fuel technologies have been incorporated in more than 500 production lines in more than 30 countries.
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 offers solutions for a wide spectrum of biomass fuels, including: wood chips, pellets, saw dust, wheat straw, barley, rice straw, bark and biogas. Biomass is CO2 neutral, which significantly reduces environmental impact. And our multi-fuel technology is the result of decades of experience with various renewable energy fuels.
BFB boilers are ideal for a wide range of biomass and high-moisture waste fuels. B&W’s bubbling fluidized-bed (BFB) top- or bottom-supported, one- or two-drum designs prove attractive in new or retrofit applications. Capacities for bottom-supported range up to 225,000 lb/h (28.4 kg/s) and top-supported from 225,000 to 1,000,000 lb/h (28.4 to 126 kg/s).
Industrial Boilers
We are a global leader in supplying a wide range of industrial water-tube boiler designs to meet targeted, challenging, long-lasting operational and performance goals for power and process applications.
Our industrial water-tube package boilers, Stirling® and Towerpak® power boilers, and fluidized-bed boilers are custom engineered to each project’s unique specifications for varying inputs and desired outputs.
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.
B&W’s Stirling® boiler has provided dependable steam to industry for more than 100 years. A proven and flexible design has made the Stirling power boiler adaptable for applications in a variety of industries using a wide range of fuels
