Power project developers are demanding significantly increased fuel flexibility in order to allow maximum utilization of local renewable biomass and recycled fuels. These multi-fuel projects are becoming more common for several reasons. First, power producers are able to take advantage of locally available and much less expensive fuel sources. Second, many nations offer feed-in-tariffs that guarantee power sale revenue at often attractive rates. Also, regional biomass plants may solve other environmental problems, such as recycling waste products into a fuel source. Finally, burning biomass with near-net-zero carbon emissions encourages many owners to retire old power or CHP systems. Taken together, these plants serving towns and communities provide reliable regional power and CHP as well as increased economic and fuel security utilizing local, indigenous fuel sources.

Europe, in particular, is now experiencing an upswing in multifuel projects, where many new plants are capable of burning a range of fuels from coal, demolition wood waste, biomass, RDF, biosludge, and even some trashes, all in the same combustion unit. The common thread is these new units are relatively small power or CHP plants that serve one or more municipalities or regions as an independent “micro-solution” that use economic local fuels to produce both heat and power. These projects were not possible with a conventional PC boiler, which is inherently limited in the amount and type of fuels that can be fired in a single unit. However, fuel-flexible circulating fluidized bed (CFB) technology empower “micro-solutions” because of its scalable size, low capital cost and its ability to take full advantage of local and diversified fuel mixes.
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.
Specific topics 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
- How the CFB is easily modified for ammonia and limestone injection for enhanced NOx and SO2control
Also presented will be case studies on several projects that promote comprehensive local energy solutions while reducing regional CO2 emissions.
- Design and performance of a 200MWe /240 MWth Jyväskylän Energia CHP plant, Finland, 100% fueled mainly by locally sourced biomass and Peat
- Design and performance of a 105MWe Multifuel CFB plant, South-Korea, fueled by PKS, Wood pellets and coal.
- Design and performance of Igelsta CHP plant, Sweden, producing 200 MWth of district heating and 85 MWe when burning a wide range of biomass and waste fuels
- Design and performance of a 75 MWe/145 MWth Multifuel CHP plant in Zabrze, Poland to be fueled by local coal, biomass and RDF
- Design and projected performance of Lahti Energia Oy’s new Kymijärvi III 190-WMth Multifuel CHP plant, Finland, capable of burning of biomass, peat, coal and REF waste
