Emerging Trends in Multi-fuel CFBs

Topics presented in the webinar will include:

• The broad range of biofuels that may be efficiently burned in a CFB, from solid biomass to biosludge and from agro waste to residential and commercial waste products.

• The low sensitivity of the CFB to fuel quality excursions when using opportunity and other low quality yet economic fuels.

• How the CFB avoids ash, fouling, and corrosion issues by incorporating step grids and an INTREX superheat/reheat heat exchanger

In this informative webinar, Timo Jantti will discuss how Sumitomo SHI FW’s advanced CFB multifuel technologies can provide highly reliable power and combined power and heat generation burning a wide-range of organic fuels while producing extremely low emissions.

Below are some of the questions discussed during the webinar:

• Do all your CFB designs use the compact design with a shared wall between the separator and the furnace?

• Is the Jyvaskyla unit the largest biomass CFB you have supplied?What is the net plant efficiency for the Jyvaskyla plant?

• Can you elaborate on the NPV number for CFB technology vs. other PV boilers?

• What about SOx and NOx emission levels? Is any special treatment required before releasing to the atmosphere?

• Is the CFB boiler efficiency lower when fired with biomass compared to coal? What is the maximum efficiency for a CFB boiler when firing with biomass?

• What is the recommendation for SOx reduction between limestone scrubbing vs. Cansolve-type solution? NOx reduction by SCR vs. SNCR?

• What is the unburnt content (TOC or Loss on Ignition) in bottom ash in the CFB when burning clean biomass?

• What percentage of carbon is present in ash?Can you elaborate on limestone particle size versus SOx removal efficiency?Could the CFBC reach choking due to excessive material feed?

• Is your boiler efficiency calculated using LHV or HHV with this combination of fuel?
