Abstract:

Biomass co­firing in fluidized bed represents among other technologies one of the most cost effective and efficient means of producing bio­energy and reducing air pollution and greenhouse gas emissions. Biomass fuels are considered environmentally friendly energy sources for several reasons: (i) there is no net increase in CO2 as a result of biomass combustion; (ii) the emissions of SO2 can be reduced by co­firing since most biomass fuels have significantly lower sulfur content compared to coal; and (iii) co­firing biomass with coal can also result in lower NOx levels. In addition, biomass co­firing mitigates the emissions of CH4 (a more harmful greenhouse gas than CO2 in terms of global warming impact) which would be otherwise released from the landfilled biomass residues. The paper presents the results, achieved in our 40 kWth BFBC facility, concerning the effect of biomass share in the fuel mix on emissions behavior as well as the measures for reducing the emissions of SO2, NOx and CO2.
