ANDRITZ Circulating Fluidized Bed (CFB) gasifier

Atmospheric systems for producing fuel gas

The basic fluidization principles are the same for fluidized bed boilers and gasifiers. For this reason, CFB gasification technology can be scaled up to very large sizes compared to most biomass gasification technologies. Read about biomass gasification in the article A major step to reduce carbon footprint in pulp mills in SPECTRUM NOW.

A CFB gasifier is fuel-flexible and can process a great variety of low-grade fuels – wood-based biomass, other biomass with sufficient gasification properties, and certain waste-derived rejects from industrial processes.

ANDRITZ CFB gasifier system

ANDRITZ has extensive experience in gasification technology and our CFB gasifiers have been in operation since the 1980s. The technology has been upgraded over the years to satisfy today’s demands for reliability, safety, and efficiency. ANDRITZ is able to provide the whole solution chain, from biomass handling to lime kiln, with the benefit of a complete warranty and customization to your specific needs.

ANDRITZ CFB gasifiers produce combustible fuel gases in a capacity range of up to 150 MW_fuel for lime kilns (lime reburning kilns in pulp mills) and for the power industry. The lime kiln gasification system can replace 100% of lime kiln oil / natural gas consumption by utilizing biomass fuels available at the pulp mills. 

Coal-fired power boilers can be converted, at least partially, to use gasifier gas from biomass. Using the existing power generation capacity to reduce CO₂ emissions is an economically viable way to burn local biomass. 

ANDRITZ provides gasification technology for new lime kiln projects as well as existing lime kilns for efforts in the defossilization of pulp mills. Our experts will support you on every step of the way from project launch to ongoing life-cycle services.
