The eq]uipment is made up of piping, valves, electrical conduit, and electrical <br />controls that conneel the entire system. External support supplies include natural <br />gas, la~flfil] gas, water (ponable)~ electric power, telephones, and supply gases. <br />The e~ernal supplies would be provided by Kahec on a temporar)., basis for the <br />len~h i0fthe demonstration. <br /> <br />Deliveries <br /> <br />Materi$1s and supplies required to support the demonstration will be delivered by <br />truck t0 the facility. Trucks will enter the site usinG~ the existing landfill entrance <br />off Sur~ish Lake t}oulevard. Personnel assigned to the project and visitors will use <br />the sarfie entrance. <br /> <br />Demonstration Process <br /> <br />A fuel _Ceil is an electrochemical power generator like a batter3.,. It converts the <br />chemical energ.,y of a fuel to e}ectrical energs' without requiring an intermediate <br />conver!ion to heat and mechanical ener~,. Because of their inherently high <br />efficienicy, fuel cells have been utilized for U.S. Space missions since the 1960's. <br /> <br />A typi '.~ fuel ceil power plant for utiliW applications consists of the following: <br />Fuel. s~ch as tandfiI1 gas is converted to a hydrogen-rich stream in a fuel <br />processor, and fed to the fuel cell which produces DC power and heat. The DC <br />power !sconverted to AC in a power conditioner. The heat produced in the fuel <br />cell is supplied to the fuel processor, to meet the heat requirements of fuel <br />processing reactions. Power plants of this type based on fuel cells have been <br />demon.dtrated in Japan,. Europe and the U.S. . <br /> ~ - <br /> <br />The molten carbonate fuel cell 0vlCFC) to be tested at Anoka Re~onal Landfill is <br />a direct, fuel cell. A direct fuel cell is a unique type of fuel cell that eliminates the <br />need fo~' a fuel processor and the associated heat transfer loop. Landfill zas fuel <br />can be directly supplied to an internal reforming MCFC, where it is converted to a <br />hvoroo~n-nch stream and subsequently to electricity. The intimacy of the heat and <br />n~ass (r sfer arrangement within this ~el cell results in a highly e~cient, simple <br />and relilable power plant. <br /> <br />Noise · <br /> <br />Fuel ce~ systems have a higher reliability than combustion turbine-combined <br />system~ or internal combustion en~nes because they contain fewer moving parts. <br />Fuel cel~s will not experience catastrophic failure as a combustion turbine or <br />internallcombustion en~ne will when rotating parts fail; they experience only a <br />~adual[loss of efficiency. The noise factor associated with the operational <br />characteristics of the landfill gas/fuel cell system will be lower than the noise level <br />of the existing blowers located at the site. The quiet, electrochemical nature of <br /> <br /> <br />
