    Co-firing of wood and coal has been demonstrated in sev-eral pulverised fuel plants in Europe and the United States. The results have been promising - boiler efficiencies have not suffered considerably. However, the maximum share of wood in the fuel blend has been small, only about 5-10%. The properties of wood biomass set demanding requirementsLearn More

  • Biomass Cofiring in Coal-Fired Boilers

    Cofiring biomass and coal is a time-tested fuel-switching strategy that is particularly well suited to a stoker boiler, the type most often found at coal-fired federal facili-ties. However, cofiring has been successfully demonstrated and practiced in all types of coal boilers, including pulverized-coal boilers, cyclones, stokers, and fluidized Learn More
