Abstract:
Basic technological challenges related to biomass combustion and co-firing have been presented and discussed. The most significant differences concerning biomass combustion behaviour comparing to coal have been identified. Influence of biomass addition on the energy efficiency of the utility boiler has also been discussed. As biomass ash composition is strongly different from the one of coal, the influence of the individual compounds (alkalis) on the risk of boiler fouling and slagging has been evaluated, in terms of different biomass sorts. Ash composition as well as emission of gaseous pollutants from biomass combustion have been assessed along with the discussion of fuel additives which are used to change the ash fusion temperatures and reduce the risk of the defluidization of the bed material in CFB and BFB biomass co-firing boilers.
