In this informative webinar, Timo Jantti, Head of Global Technology for Amec Foster Wheeler, will review each of these biomass CFB projects as well as the advances in CFB technology which make these projects possible. 

This webinar can help you make informed decisions about CFB boiler selection and fuel utilization options for new biomass firing applications. 

Below are some of the questions discussed during the webinar:

  • Do all your biomass CFBs use the INTREX to protect the high-temperature superheater coils from the corrosive flue gases?

  • Can you give advice on fuel flexibility vs. boiler cost? Which fuels cause you to move away from your "standard" design to more expensive robust designs?

  • What are the criteria to select gasifier vs. CFB technology? What are the fuels used in AFW gasifiers?

  • What is the typical CAPEX per MW for small, mid, and large-scale biomass CFB boilers?

  • Which international codes and standards do you follow in your boiler design?

  • What are the fuel preparation requirements, especially when using multifuels?

  • What was the driver to select CFB over grate technology for your South Korean plant?

  • What type of pre-treatment is required for biomass fuel before introducing it in the CFB boiler?

  • What is the maximum moisture content in the biomass fuel that a CFB boiler can tolerate without adversely affecting combustion and emissions?

  • What is the minimum calorific value of biomass required for CFB technology?

  • Is there a significant change in material selection for designing flue gas ducts and downstream equipment for a biomass-fired CFB?

  • For coal and biomass co-combustion CFB, should the biomass fuel be stored and fed into the furnace separately or blended with coal and stored in the same fuel silo before feeding into the furnace?

  • Given the integral cyclone furnace design eliminates the need for maintenance-intensive expansion joints at the cyclone inlet, how is thermal expansion and thermal gradients handled?

  • What solutions do you have to avoid high-temperature chlorine corrosion for fuels like recycled wood and waste? Do you have something similar to Valmet's double-tube system for high-temperature corrosion protection? What materials are used in steam temperatures of 500°C? What dioxin levels can Foster Wheeler guarantee, or have studies been conducted on this issue? Increased heat absorption in INTREX cascade reheaters—do you have this in your new plants?
