In this informative webinar, Marko Natunen, Senior Project Manager will review the design features and performance characteristics of Amec Foster Wheeler’s advanced bio CFB technology utilized at the Polaniec Power Station. The following topics will be addressed:

  • How to achieve high plant efficiency with biomass fuels

  • How to mitigate boiler agglomeration, fouling and corrosion with biomass fuels

  • Quantifying fuel risks for agglomeration, fouling, and corrosion for specific agro biofuels (sunflower husks, wheat straw, olive waste, palm kernel shells, etc.)

  • Reduction in boiler fouling, corrosion, and maintenance by preventing ash melting

Below are some of the questions discussed during the webinar:

  • Can different biofuels be used in a unit without mechanical modifications to equipment and pressure parts?

  • What are the additives used in multi-solid biofuel applications?

  • Do you have experience in the construction of steam generators? Do you know anything about the construction of 300 MW biomass boilers?

  • What is the auxiliary electricity consumption for maintaining the fluidized condition in the CFB? What is the percentage of this with respect to the gross electricity generation?

  • What is the particle size of biomass needed to be fed into the CFB?What is the lowest capacity CFB provided?

  • In plants burning 100% wood chips and/or pellets operating with a "high dust slip catalyst," what is typically the guaranteed/expected lifetime of the catalyst? Is there any risk of poisoning (e.g., from alkaline metals or phosphorus)?

  • What is your target for furnace temperature to avoid agglomeration with the Polaniec fuels mixture?

  • Could you explain why there is no addition of specific additives while burning agro-fuels with a high risk of agglomeration in the Konin project?

  • What is the INTREX section of the boiler? Why is it important and what difference does it make to install the latest stages of the RH/SH at the INTREX?

  • Could you clarify how it would be possible to burn sticky particles? Do you need to change anything in your design?

  • Is the CFB design able to follow cycling mode operation with regular shutdowns, for instance during the weekend?

  • Has rice husk and sugarcane bagasse been tried as feed in CFB? How was the efficiency in case it was tried?

  • What is the maximum electrical net/gross efficiency you intend to achieve with the advanced ABC CFB operating on "clean" biomass, e.g., wood pellets?
