1/3/2003 · For FORTUM, the main arguments in favour of co-firing biomass and coal in their PC boilers are: •. Pressure to reduce CO 2 emissions in the existing coal-fired power plants→ Directives and measures of support for the use of biomass → High taxation of fossil fuels for energy production. •.

Co-firing coal with biomass is a potentially valuable tool to help decrease greenhouse gas and other emissions in coal-fueled boilers. Use of biomass at low to moderate biomass to coal ratios appears to produce the best performance enhancements and can result in overall life-cycle energy consumption reductions, as well as reduced solid waste generation.
