Co-firing Biomass with Coal - energy.psu.edu

2012-5-11 · Co-firing biomass is a good option for coal-fired combustors in Pennsylvania because • the solid biomass fuel can be added to the fuel stream, • the addition of biomass to the fuel reduces emissions of sulfur, and • biomass fuel is essentially carbon neutral. However, there are some challenges associated with biomass co-firing, including
