ANDRITZ PowerFluid boilers are based on Circulating Fluidized Bed (CFB) technology to produce steam and electricity from nearly all solid fuels from coal and biomass to alternative fuels and wastes. PowerFluid boilers employ proven, yet modern combustion technology to efficiently produce power while keeping emissions within environmentally safe limits.
A major challenge for power generators is how to balance the variations in fuel pricing and availability in order to profitably generate power while producing minimal emissions. To meet this challenge, plants need the flexibility to utilize a wide range of different fuels in order to ensure supply stability at the lowest possible cost.
CFB technology is best for multi-fuel combustion and the ability to use diverse fuels of differing quality. The diversity of fuels ranges from conventional (coal, oil), to biomass, to alternative (biogenous residues, sludge, rejects, and refuse-derived waste fractions with high calorific value). The high heat capacity of the fluidized bed evens out the fluctuations caused by fuel quality variations and effectively maintains combustion.

PowerFluid boilers combine standardized modules which can be flexibly configured with strongly custom-tailored features for optimum performance. PowerFluid boilers have unequaled fuel flexibility (including fuels which are difficult to burn), high efficiency, and the ability maintain almost complete combustion with the lowest emissions of nitric and sulphur oxides.
