Bubbling Fluidized-Bed Boilers

 DOWNLOAD

Since 1867, industries worldwide have benefited from The Babcock & Wilcox Company’s (B&W) engineering expertise, manufacturing technology and operating experience as a major supplier of steam generating equipment. We continue this tradition as a leader in reliable steam generation with our bubbling fluidized-bed (BFB) boiler.

B&W’s involvement with fluid-bed technology began in the 1950s with the first combustor at its state-of-the-art research center in Alliance, Ohio. Now, with an experience base of more than 30 BFB units, these facilities are helping the world realize the promise of clean energy from a wide variety of fuels.

B&W’s bubbling fluidized-bed boilers can burn a wide range of low-cost opportunity fuels.

The ability to utilize various fuel sources and types provides owners with the flexibility to take advantage of changing cost and availability.

B&W’s BFB boiler is designed with a very large operating window to allow a wide range of fuels to be burned, separately or in combination.

This is necessary because fuel properties vary widely. For example, biomass fuels have a wide range of moisture and heating values depending upon their source and the time of year.

Our BFB boilers are designed with a high degree of flexibility to facilitate air movement between the bubbling bed and the overfire air system, to vary the gas recirculation volumes, and to adjust the fuel delivery to the bed. This operational flexibility allows owners to burn cheaper opportunity fuels and control fuel costs.

Whether you’re considering a new BFB boiler, or a conversion of your recovery, stoker-fired power or small utility boiler, fluidized-bed combustion offers significant operational advantages:

• Fuel flexibility

• High efficiency

• Low environmental emissions

• Reduced capital costs and operating expenses
