Municipal Solid Waste as an Energy Source by Roller-Grate Incineration
MetadataShow full item record
The Grumman/VKW (Duesseldorf) Roller-Grate System was developed specifically to mass-burn municipal solid wastes achieving efficient combustion by a rolling and mixing action of the fuel bed, and independent control of primary air and roller speed. Since 1965, water wall boilers equipped with roller-grates have been transforming a variety of municipal wastes into energy in Europe and Japan. The system and its capabilities are explained. Application of this technology to a United States site is considered. The factors of population size, waste input, energy output, energy customer requirements and the potential benefits to municipalities and industry are discussed. Firm agreements covering waste and energy revenues are essential, as is the ability of the plant to constantly receive refuse and produce power for its customers Methods of achieving this reliability are explained The conservation of conventional fuels through the incineration of municipal wastes holds promise when the combination exists of a municipality willing to make a long-term commitment of its refuse and an industrial customer seeking a source of energy. Bringing these parties together is a challenge which refuse power advocates face with cautious optimism.
