Biomass fired boilers

Competitive solutions and proven technologies based on decades of development and experience

 


BWE offers a wide range of biomass boilers for a variety of bio fuels. The boiler designs are based on proven technology and optimized for power production. Elevated steam parameters combined with state-of-the art combustion systems is your guarantee for reliable solutions and high plant efficiency.

BWE boilers have high fuel flexibility and solutions are available for all virgin fuels – from traditional wood chips to agricultural residues with high chlorine / high alkali content such as cereal straw.

Grate fired boilers

BWE grate fired boilers are available in the range of 50 to 132 MW heat input. The boiler is a bottom supported, natural circulated drum type boiler, with membrane walls and hanging super-heaters. The combustion takes place on a water-cooled vibrating grate, controlled by a 3-zone combustion air system. A special designed heat displacement system eliminates corrosion in the boiler cold end.

Additional features:

  • Wet bottom ash conveyor system
  • Integrated SNCR system for NOx reduction (optional)
  • Stoker feeding for straw (up to 40% supplementary firing of e.g. wood chips)
  • Spreader feeding for chips

Pulverized fired boilers

BWE PF fired boilers are available in the range of 50 to 800 MW heat input. The boiler design ranges from bottom supported natural circulated drum type boilers in the lower capacity range, up to hanging once-through boilers (tower type) with ultra super critical steam parameters in the high capacity range. The pulverized biomass are burned in suspension by multifuel Low NOx burners in a front, boxer or tangential arrangement. The combustion is controlled by an advanced 4 zone combustion air system.

Additional features:

  • Wet or dry bottom ash conveyor system
  • Rotating air pre-heater arrangement
  • High fuel flexibility and 100% back-up load by gas/oil
  • Special design available for high chlorine fuels
