Ecofluid BFB boilers (5-100 MWel):
In addition to typical biomass fuels such as wood (chips, bark, forest residues, and sawdust), more recently short-rotation energy crops, sludges, rejects, agricultural wastes, and refuse-derived fuels (RDF) are being introduced as fuel sources. Common characteristics for these fuels are that they are high in volatile matter and have a high variance in moisture content. These alternative fuels require certain considerations in design as well as in the steam output parameters. ANDRITZ has technical solutions for a broad range of fuels that can be burned in an EcoFluid boiler.
Scalable and reliable
EcoFluid boilers can be either top- or bottom- supported, depending on the desired capacity and site conditions. Scalability and ease of construction are enhanced since the main boiler components are designed as modules. The arrangement of all heating surfaces is tailored to the customer’s requirements. The boilers are conservatively designed with regard to materials of construction, location and spacing of heat surfaces, etc. to ensure high plant availability and low maintenance requirements
PowerFluid CFB boilers (20-300 MWel):
Freedom of choice: multi-fuel design
This enables the PowerFluid boiler to employ fuels of differing quality and source – giving plant operators the freedom to take advantage of changing market conditions and fuel supplies. The modular CFB design of an ANDRITZ PowerFluid boiler enables the boiler to utilize conventional and alternative fuels. The core components are standardized to deliver efficient, reliable performance. In addition, many features can be customtailored for optimal performance in each installation. In addition to firing conventional fuels (coal, lignite, and biomass), PowerFluid boilers have proven reliable in firing such fuels as biogenous residues, sludge, and rejects or waste fractions with high calorific value (RDF). These can be fired as the primary fuel or in combination with others.
