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.
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 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 CFB gasifiers produce combustible fuel gases in a capacity range of up to 150 MWfuel for 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 delivers high-quality, proven technology gasifiers for lime kilns and boilers with auxiliary systems and biomass fuel handling.
