fuel cells eliminates many of the sources of noise associated with conventional <br />steam-powered systems, thus easib' compl~ng with OSHA standards. <br /> <br />Odor Control <br /> <br />Landfills are becoming a national environmental problem due to concerns for gas <br />explosion, odor and release of emissions into the atmosphere. As the gas is <br />formed and pressure builds, i~ can migrate to the surface and can explode if ignited <br />bv a spark. The presence of sulfur in the refuse cremes mercaptans which have a <br />distinct rotten-egg smell. The Anoka Regional Landfill has implemented an active <br />control system to include the installation of horizontal and vertical gas extraction <br />wells. The riow of landfill gas mixture is maintained by creating a slight vacuum so <br />as to induce a pressure ~adient toward the extraction well. The extracted gas is <br />fuhrer processed through controlled burning (flaring) which diminishes the toxic <br />odor. <br /> <br />The demonstration project plans to utilize the landfill gas flow prior to the existing <br />flaring process. The landfill gas will be introduced into a clean-up processing <br />system removing the contaminates, including sulfur prior to the final processing to <br />the fuel cell. Since the fuel cell processing system is a closed vessel ail gases are <br />controlled and managed. Because of the system design, the presence of odors <br />would be less than current existing odors at the sire. <br /> <br />Finished Product <br /> <br />Under normal operational conditions the output of the fuel cell system would be <br />the generation of AC power. This demonstration goals are specifically to show the <br />potential of using landfill gas as a fuel supply. The output of this demonstration <br />will be DC power from the fuel cell to the load bank and further processed as <br />generated heat rather than electricity,. <br /> <br />6. Present Zoning District <br /> <br />The proposed location of the facility is zoned for industrial purposes by the City of <br />Rarnsev. The facility,' is considered industrial in nature and meets the zoning <br />reouirements for this location. <br /> <br />7. Site Map <br /> <br />A site map and facility layout is included in Attachment 1. <br /> <br /> <br />
