pelletizing. Pelletizing is the compression of "fluff" RDF into dense pellets generally <br />to be fired along with lump coal. The pellet size depends on the size of the coal used <br />in existing power plants. <br />RDF production is a distinct process; therefore, it is not necessary to be co-located <br />with the combustion plant. In Figure B-4, RDF in blown into the furnace from the <br />left, -above the grate. What does not burn in suspension (above the grate) will burn <br />on the, grate, and the hot gases generated will pass through a wabenwa|| section and <br />then a boiler section. This system is similar to the mass-burn wahanwa|| facility <br />except in the nature of waste changing and burnout. <br />VEAM <br />FOR INMN'nty <br />� <br />and MAIIOC�: <br />Nirf <br />arkI <br />Figure B-4. TypicaURDF CommbustiomFacila�v <br />The unique feature of RDF systems is in the pre-processing of waste. As seen in the <br />diagram of typical RDF processing facility in Figure B-5, MSVV enters the facility and <br />then passes through a tnornnne|, where bags of waste are broken open and large <br />material is removed. The snna|| nnataha| dropping out of the firsttrornnne| pauses <br />through second trammel to remove fine noncombustible material. The majority of <br />waste goes through a shredder for size reduction. A magnetic separator removes <br />ferrous metals and the balance of the material is fired in the furnace. <br />»Source: Energy Answers Corporation. <br />GBB/C08027-01 B-7 August 15, 2008 <br />
