Biomass boilers

Pulverized fired

Our boiler solutions use proven technologies that draw on decades of development and experience

We offer a wide range of biomass boilers for a variety of bio fuels, either as part of a turnkey EPC contract or as only a boiler or boiler island.

Our boilers range from 15-70 MWe and are optimized for power production. Elevated steam parameters combined with state-of-the art combustion systems guarantee reliable solutions and high plant efficiency.

Our boilers offer high fuel flexibility and solutions are available for all virgin fuels. Traditional wood chips or agricultural waste products with high chlorine / high alkali content can be used.

Pulverized-fired boilers

We can build pulverized-fired boilers with a heat input range of 50-800 MW. 


The boiler design ranges from bottom supported, naturally circulated drum type boilers in the lower capacity range to hanging once-through boilers (tower type) with ultra, super-critical steam parameters in the high capacity range. The pulverized biomass is burned in suspension by multifuel, low NOx burners in a front, boxer or tangential arrangement. The combustion is controlled by an advanced four 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 designs for high chlorine fuels
