The bubbling fluidized bed (BFB) technology employed by ANDRITZ Carbona for biomass gasifiers can be operated at any reasonable pressure and is a valuable technology to mitigate climate change. The technology was originally licensed from the Gas Technology Institute (GTI) in the United States (U-gas and Renu-gas processes). ECOFLUID bubbling fluidized bed boilers form an important part of ANDRITZ bio-energy solutions and are used for steam and power generation from biomass and different alternative fuels, such as sludges, RDF, and residues. The scale-up of bubbling fluidized bed reactors to commercial size is a complex and troublesome endeavor. In particular, the proper scale-up of the hydrodynamic.
Valmet’s boiler solution utilizing bubbling fluidized bed (BFB) combustion technology is called HYBEX. Wide fuel flexibility, high combustion efficiency, high reliability, excellent controllability and low emissions have turned it into a real winner, with over 200 deliveries and boiler conversions around the world. FSE Energy offers utility and industrial grade Bubbling Fluidized Bed (BFB) boilers capable of producing 35K PPH to 650K PPH of superheated steam.
