Sustainable cofiring of biomass with coal - ScienceDirect

1/6/2003 · Biomass is an attractive renewable fuel to supplement coal combustion in utility boilers. Coal cofiring was successful with up to a 20% biomass mix. Results of extensive applications have shown that cofiring of biomass with coal have accomplished the following: (1) increased boiler efficiency, (2) reduced fuel costs and (3) reduced emissions of NO x and fossil CO 2 .
