• Woody commerce stream materials such as discarded pallets, logging or milling by-products, and forest slash. The biomass would be chipped in the fields so that at least 90 percent of the biomass would be no more than three inches in nominal size. It is expected to have a moisture content of 35 to 50 percent by weight (see Table 2.2) . To avoid odors due to decomposition, putrescible feedstocks such as fruit, manure, and municipal solid waste would not be accepted. The briquetting/pelletizing system equipment is designed for a maximum input rate of 30 tons per hour (50 percent moisture content - wet basis) . To obtain the desired ten-day supply, a total volume equivalent to a single pile 500 feet by 250 feet and 15 feet in height would be required. However, this volume would be segmented into at least four and as many as twelve separate piles, depending on the type of biomass avail - able at any given time during the year. Segmentation of the pile is also required for pile management and fire control . Feedstock pile management (by front end loaders) would be on a first-in/first-out basis to elimi- nate the potential for decomposition, hence eliminating odor and energy loss. The raw biomass would be loaded into a Reclaim Hopper and conveyed to the primary classification station. A single-deck classifying screen (shaker screen) would be used to separate out oversized chips (i .e. , greater than one-half inch in diameter) . The oversize material would be reduced to the appropriate size by a Hammer Hog. A Magnet would remove tramp metal which might damage the hog. A belt-type Outfeed Conveyor would lift the classified biomass to a Splitter that can direct material to the Dryer Distribution Flight Conveyor at the intake to the Dryers, or bypass the Dryer and go directly to the Briquetter Feed Hopper. The Distribution Conveyor would be designed to maintain the Dryer Feed Hoppers full at all times. At the base of each Dryer Feed Hopper, a Rotary Airlock Feeder meters the classified biomass into the dryer intake chute. The Dryers are triple pass, direct heating, rotary drum type. Induced draft convey- ing air moves the feedstock the length of the Dryer as the drum rotates. 2-12 I01-46.R5 4/13/89
