pelletizing. Pelletizing is the compression of "fluff" RDF into dense pellets generally <br />to be fired along <br />with |unnp coal. The pellet size depends on the size of the coal used <br />in existing power plants. <br />RDF production is distinct process; therefore, it is not necessary to be co-located <br />with the combustion plant. In Figure B-4, RDF is blown into the furnace from the <br />left, above the grate. What does not burn in suspension (above the grate) will burn <br />"' <br />on ~ e grate, nd the hot gases generated will pass through a wabanwa|| section and <br />then a boiler ` section. . This system is similar to the mass-burn vvatanwa|| facility <br />except in the nature of waste charging and burnout. <br />Figure B_4^ Typical RDF Combustion FaclDeys <br />The unique feature of RDF systems is in the of waste. As seen in the <br />diagram of a typical RDF processing facility in Figure B-5, MSW enters the facility and <br />then passes through a trommel, where bags of waste are broken open and large <br />material is removed. The small material dropping out of the first trommel passes <br />through a 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 />^Sourca: Energy Answers Corporation. <br />GBB/C08027-01 B-7 August 15, 2008 <br />
