Cofiring Steam Boiler Related Information

  • Cofiring high ratios of biomass with coal

    biomass by weight or 10% by energy output. Cofiring can be direct, where the biomass and the coal are fired in the same boiler or indirect, where the combustion or gasification of the biomass occurs in a separate unit. Direct cofiring is the simplest and most widely applied technology for cofiring biomass.Learn More
