PowerFluid circulating fluidized bed boilers

Unmatched fuel flexibility – from biomass to alternative fuels and waste products. CFB technology is the state-of-the art technology for multi-fuel combustion.

ANDRITZ PowerFluid boilers are based on Circulating Fluidized Bed (CFB) technology to produce steam and electricity from nearly all solid fuels from 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.

PowerFluid CFB solutions

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.

Benefits of the PowerFluid boiler

Power boilers

Technologies for producing steam and electricity from renewable fuels as well as for the efficient use of traditional fossil fuels.

EcoFluid BFB boilers

Based on Bubbling Fluidized Bed (BFB) technology for producing steam and electricity from solid fuels such as renewable biomass and alternate fuels such as sludge, Refuse-Derived Fuel (RDF) and residues.

Air- and water-cooled reciprocating step grate

Most modern power plants for the production of energy from waste (EfW) use the proven technology of heat treatment on mixed municipal waste, RDF and SRF. Air- and water-cooled combustion grates and tailor-made boilers, which are manufactured in our European facilities, are the core components of most current EfW plants.
