Solid Fuel Boilers Circulating Fluidized Bed Combustion

Circulating Fluidized Bed

FSE Energy offers utility and industrial grade Circulating Fluidized Bed (CFB) boilers in the output range of 150K PPH to 1000K PPH. FSE Energy can provide the full scope of engagement to deliver a turn-key power or cogeneration plant including engineering, design, fabrication, procurement, construction, balance of plant work and aftermarket services.


  • Low Operating Costs – the CFB has the absolute greatest range of fuel flexibility of any combustion technology available with the ability to utilize extreme high and low moisture content fuels and mid-level containing alkali fuels not viable on other combustion technologies. The CFB protects the owner against future fluctuations in fuel prices by allowing the owner to change fuels at any given time. This allows for significantly reduced fuel costs.
  • Low Capital Costs – FSE Energy has the reputation for offering the highest quality equipment at the best possible value.
  • Lowest Overall Uncontrolled Emissions – CFB systems offer the industry’s lowest emissions from NOx, SO2, CO, VOC’s and PM.
  • Highest Efficiencies – CFB technology offers the industry’s highest efficiency in terms of the combustion process, thereby reducing the overall amount of fuel used, and lowering long term operating costs.

The FSE Energy experts bring over 75 years of experience and unparalleled value and quality to the boiler marketplace.
