Bubbling Fluidized-Bed Boilers

Bubbling Fluidized-Bed (BFB) Boilers

B&W’s BFB boilers are designed to allow a wide range of fuels to be burned, separately or in combination. The ability to utilize various fuel sources and types provides owners with the flexibility to take advantage of opportunity fuels and control fuel costs.

B&W’s advantage

B&W’s BFB boiler is designed with reliability in mind. Several features combine to provide low maintenance costs, high availability and long-term reliability:

  • An open bottom design permits easy removal of oversized or foreign material.
  • A water-cooled, gas-tight lower furnace eliminates the potential for gas leaks caused from refractory damage.
  • Bottom-supported hoppers remove load from the boiler, reduce capital requirements, and reduce potential mechanical stresses between water-cooled and non-cooled components.

University of Missouri

Project / Case Feature Items

University of Missouri
Missouri, USA

B&W designed, engineered and supplied a biomass-fueled bubbling fluidized bed (BFB) boiler to replace the University of Missouri’s existing coal-fired boiler, and to provide the university campus with electricity and steam for heating and other uses. Designed to burn chipped hardwoods and various local opportunity fuels near the university campus, the boiler will produce lower sulfur dioxide emissions and less ash than a typical coal-fired boiler.
