Thermal - MSW and RDF
Direct Combustion Mass Burn and Refuse Derived Fuel
Mass Burn facilities have been in existence for decades and as the technology reflects it literally burns/combusts everything, leaving only noncombustible material. There are over 100 of these facilities operating in the U.S. and considerably more in Europe and Asia. Refuse Derived Fuel (RDF) is the process of removing the recyclable and noncombustible from the municipal solid waste (MSW) and producing a combustible material, by shredding or pelletizing the remaining waste. There are only 19 RDF facilities in the U.S., but as energy prices climb and landfill permitting gets more difficult there may be an increase in the number of these facilities. Figure 2 and 3 are B&W’s rendition of typical Mass Burn and RDF technologies.
