Abstract

This chapter overviews direct co-firing applications of agricultural and forestry residues with coal in fluidized bed combustion (FBC) systems, which is the most promising technology due to its fuel flexibility and high efficiency. Similarities and differences in characteristics of biomass and coal are summarized. Issues on operational problems and their possible solutions in FBC systems firing biomass only are identified. Among the available solutions to these problems, co-firing biomass with coal is the most effective and simple option. Experiences obtained from several biomass/coal blends in FBC systems, ranging from laboratory rigs to large-scale utility boilers, are presented to emphasize the impact of co-firing on combustion efficiency, emissions and ash-related operational problems.
